01 | THEME 01: SOLAR SYSTEM AND PLANETS

Submissions Closed
Geochemical, geodynamical, and astrophysical studies have led to major advances in understanding the origin(s) and evolution of our and other planetary systems. The goal of this theme is to bring together inter-disciplinary contributions that address key questions about how solar systems form and evolve through time. Topics of interest include protoplanetary disks, planetary accretion and planetesimal growth, planetary collisions and volatile transfer, planetary differentiation and crust formation, as well as impact and magmatic processes on rocky bodies. We seek sessions that bring together different methodologies, including analysis of extraterrestrial materials, experiments and numerical modeling, observations of exoplanetary systems, and results from surface missions and remote observations of planetary bodies.

02 | THEME 02: MANTLE AND CORE

Submissions Closed
The mantle and core make up most of the Earth’s mass, and shape its long-term evolution and present-day surface conditions. Convection in the mantle drives plate tectonics and accommodates large-scale material cycles that stabilize clement surface conditions over billions of years. Convection in the core sets up the Earth’s magnetic field that protects the atmosphere and surface from solar particles. Nevertheless, the deep interior of our planet remains poorly understood as not being directly accessible. The study of the mantle and core is restricted to indirect methods such as observational and theoretical geophysics, geodynamics, experimental petrology and mineral physics, as well as geochemical analyses of natural mantle-derived magmas and rocks (massifs, xenoliths and xenocrysts). Accordingly, recent progress in our understanding of the deep Earth has often come from interdisciplinary and synergetic efforts across the Earth Sciences. In this theme, we invite contributions to further understand the physical and chemical processes that shape the evolution and present state of the mantle and core of the Earth and terrestrial planets on various temporal and spatial scales. This call includes but is not limited to topics such as the structure, composition, formation and evolution of the core; core-mantle interaction; the oxidation state of the mantle over time; deep-mantle mineralogy; mantle melting; large-scale cycling of heat, rock and volatiles; mantle outgassing and ingassing; as well as the origin, evolution and detection of mantle heterogeneity using geophysical, geodynamic, and geochemical methods.

03 | THEME 03: EARTH'S LITHOSPHERE THROUGH TIME: FROM HADEAN TO MODERN

Submissions Closed
Earth’s lithosphere preserves an integrated, fragmentary record of the evolution of mantle–crust–hydrosphere–atmosphere interactions through time, from the Hadean to the Phanerozoic. This theme invites broad and interdisciplinary sessions that address the evolutionary history of the lithosphere, from the scale of minerals to continents. Potential topics of interest include: the formation and the evolution of the lithosphere and mantle reservoirs from the Hadean/Archaean to the Phanerozoic; the growth of the continental crust and its impact on the depleted upper mantle; multi-scale evidence of the early functioning of plate tectonics, and of the global onset of plate tectonics; the timing and rates of mantle melting and lithosphere-mantle coupling processes, and the origin of mantle heterogeneities; the record of processes and timescales in the evolution of the continental and oceanic crust; changes in the thermal state and the oxidation state of the mantle through time; paleo-geographic/magnetic reconstructions of the continental lithosphere; interrelationships among internal (crust and mantle) and external (atmosphere and hydrosphere) reservoirs, and their impact on the evolution of the biosphere; innovative tools applied to lithospheric processes and their evolution through time. We encourage geochemists, mineralogists, petrologists, geophysicists, (geo)biologists and field geologists to submit sessions that address these topics through investigations of natural samples, experiments, and modelling.

04 | THEME 04: PRESENT-DAY CRUSTAL PROCESSES, FROM FORMATION TO DESTRUCTION

Submissions Closed
Today, the crust is formed and destroyed due to plate tectonic processes. The bimodal surface elevation of the high-standing continental crust and low-lying oceanic crust reflects different physical-chemical properties and crustal thickness. How the mass balance of the whole crustal volume is maintained remains mysterious. Oceanic lithosphere is created by magmatism at divergent boundaries and the present-day continental crust is mainly formed through magmatism at convergent margins, either in island arcs or continental arcs. Additionally, intra-plate volcanism and underplating generates new crust in both oceanic and continental areas. The crust in convergent boundaries is modified by deformation and metamorphism and destroyed by subduction and delamination. Erosion and weathering affect exhumation of crustal materials and cause preservational bias in different tectonic settings. The coupling between deep dynamics and surface processes control mountain building, basin formation, element cycles, landform evolution as well as global climate change. This theme aims to organize multidisciplinary sessions. Topics of interest include, but are not limited to: the formation of oceanic crust at divergent plate boundaries; subduction zone processes; intra-plate magmatism and processes in the present-day oceanic and continental crust; reworking and formation of continental crust in arcs and collisional orogens; interaction between crustal processes and surface processes. We encourage the submission of sessions that bring together field observations, geophysical data and modelling, analytical and experimental geochemistry, petrology, structural geology as well as geodynamics to address the multitude of processes that shape, form, modify and destroy the present-day Earth’s crust.

05 | THEME 05: MAGMATISM AND VOLCANISM

Submissions Closed
Magmatism and volcanism shape the long-term evolution of planets, including the formation of crust, the development of life, and present-day surface conditions. Volcanism, the ultimate expression of mass transfer from the interior, also presents a significant hazard to large and vulnerable populations. Studying magmatic processes is therefore of crucial interest to both fundamental understanding of the planetary evolution and the mitigation of volcanic risks. This theme will convene multidisciplinary sessions dealing with both fundamental and applied geochemical advances in studying magmas and volcanoes.Acquisition of new samples, new experiments, and new observations, coupled with developments in analytical and modeling techniques, are providing us with greater insight into modern and ancient magmatic and volcanic processes. We thus welcome sessions that explore magmas and volcanoes from numerous perspectives – laboratory, field, numeric – to arrive at greater integrated understanding of igneous processes and their consequences for both the planet and people.

06 | THEME 06: NANO TO MICROSCALE PROCESSES

Submissions Closed
The study of all natural processes on Earth and other extra-terrestrial bodies eventually leads us to the micro- to nanoscale. This theme welcomes contributions across all sub-disciplines of Earth and planetary sciences, exploring how the macroscopic physical and chemical properties of rocks and minerals are ultimately controlled by processes occurring at the atomic scale upwards. New experimental and modelling techniques enable the behaviour of Earth and planetary materials to be predicted, observed, quantified and correlated across multiple length scales, leading to new understanding of equilibrium and non-equilibrium processes driven by changes in extrinsic system variables (e.g., temperature, pressure, stress, fluids). This theme embraces all aspects of how microstructures, including interfaces, grain boundaries, mineral surfaces and other defects, control a broad range of mineral properties and processes, from magnetism and rheology to mineral formation and weathering.

09 | THEME 09: EARTH SURFACE PROCESSES FROM WEATHERING TO CLIMATE CHANGE

Submissions Closed
Processes that operate at Earth’s surface are inherently intertwined, creating complex feedbacks between weathering, biogeochemical cycling, hydrology, and sediment production. Direct connection to the atmosphere also couples Earth surface processes to short-term weather patterns and long-term climate change. Both a deep understanding of individual processes and the connections between them are important to advance our knowledge of how Earth’s surface operates and responds to or influences climate change. In this theme, we encourage sessions that explore the fundamental controls and coupling of various aspects of Earth surface processes and/or climate change across disciplines, scales, and systems. For example, sessions might focus on (i) observational records of Earth surface processes or paleoclimate that shed light on coupled processes, (ii) integration of data and numerical simulation that elucidate connections between Earth surface processes and climate change, (iii) advances in predictions of rates of Earth surface processes or impacts of climate change, (iv) experimental approaches that test hypotheses related to driving mechanisms or large-scale implications, and (v) connections between Earth surface processes and society. Sessions related to predicting the impact of changing climate on Earth surface processes and ecosystems and vice-versa are of particular interest. As Earth surface processes and impacts of climate change operate across a range of temporal scales (from geologic time to milliseconds) and spatial scales (from continents to pores or mineral surfaces), we encourage sessions aimed to connect studies of behavior and mechanisms across scales.

10 | THEME 10: GEOBIOLOGY: LIFE IN GEOLOGICAL PROCESSES

Submissions Closed
Biological processes exert such a strong influence on the Earth system that life itself could be considered a geological agent that redistributes elements, minerals and rocks around the planet. These interactions stretch from the Earth’s surface down to the specialized communities that persist in the depths of the continents and oceans, and occur on a huge range of time scales. This theme invites contributions that use biological, palaeontological, geochemical or geological approaches to probe the impact of life on the geosphere. This includes, but is not limited to: the origins of life, the functioning and evolution of biogeochemical element cycles, major transitions or extinctions in Earth’s history, the preservation of biosignatures, the proliferation and impact of life in the subsurface, microbe-mineral interactions, and life in extreme environments or on other planetary bodies. We also seek sessions highlighting novel tools or approaches that expand our capabilities to work at the intersection of biology and geology.

11 | THEME 11: METALS AND NUTRIENTS IN TERRESTRIAL AND FRESHWATER SYSTEMS

Submissions Closed
The availability of metals, metalloids and nutrients in natural systems is critical to the survival of all life on Earth and are intimately linked via biogeochemical cycling. Such cycles are relevant at both the nano- (e.g. molecular) and macroscale (e.g. continental); affecting water quality, ecosystem functioning, human health and climate. The aim of this theme is to provoke discussion on the geochemical and biological processes that control the cycling of metals, nutrients and metalloids in terrestrial and freshwater systems. The discussion includes the underlying mechanisms and fluxes of the cycles, but also the coupling of cycles, anthropogenic perturbations, or their implications for climate change and human health. We encourage submission of sessions with a clear emphasis on one of the following aspects (1) process (e.g. redox reactions, mineral (trans)formation, plant uptake), (2) systems (e.g. soils, wetlands, aquifers, watersheds), (3) element or type of element (e.g. nutrient, metalloid, metal, phosphorus), (4) context (e.g. climate change, anthropogenic influence, human health), or (5) approach (isotope analysis, modelling, spectroscopy).

12 | THEME 12: ENVIRONMENTAL GEOCHEMISTRY AND HUMAN HEALTH

Submissions Closed
The geochemistry of air, soils, surface water and groundwater mediates exposures to many metals and metalloids that affect human health. Exposures to such elements can be exacerbated by anthropogenic perturbations such as mining, agriculture, land development and manufacturing. Many adverse health effects such as cancer, neurotoxicity, metabolic disruption, endocrine effects and immunotoxicity have been linked to exposures of trace metals and metalloids such as arsenic, cadmium and lead, radionuclides, and organic pollutants. Conversely, deficiencies of elements such as such as iodine, selenium and zinc in soils can lead to a variety of health problems and increased morbidity. The diverse array of interactions between humans and the geochemical environment are particularly pertinent to the health of communities where an intimate relationship with the land has endured, and are accentuated by external factors such as population growth, climate change and our growing exploitation of geochemical resources. This is especially the case in low- and middle- income countries, which tend to be heavily invested in primary industry sectors, where untreated groundwater may be used for drinking and where subsistence crops often form a large part of the diet. This theme will focus on the geochemical processes and parameters that underpin human health, covering aspects such as causation, behaviour, impact and mitigation. Topics could include, but will not be limited to: contaminant emissions from anthropogenic and geogenic sources; contaminant fate and transport within the environment; human exposure and health effects; monitoring, measurement and modelling; remediation and intervention.

13 | THEME 13: CHEMISTRY OF THE OCEANS AND ATMOSPHERE: NOW AND THROUGH TIME

Submissions Closed
The fluid envelopes surrounding the solid Earth play a fundamental role in our planet’s habitability. The chemistry of the ocean and atmosphere has evolved dramatically over Earth’s ~4.5 Ga history, while anthropogenic perturbations are driving equally remarkable changes on the timescale of a human lifetime. This theme focusses on the chemical evolution of the ocean and atmosphere in the past, present and future. We welcome sessions investigating the distribution and transformation of chemical substances in the ocean and atmosphere. This includes processes internal to the ocean (e.g., biogeochemistry, ocean circulation), chemical cycling in the atmosphere (e.g., chemical reactions and transport) and fluxes between the ocean, atmosphere, terrestrial biosphere, cryosphere, sediments, and geological reservoirs. We encourage sessions inviting the use of geochemical records to extract information about the evolving ocean-atmosphere system (i.e. paleo studies and proxy development), the development and application of modelling approaches, and the utilization of experimental techniques to constrain the (bio)(geo)chemical cycling of elements throughout the environment.

14 | THEME 14: GEOCHEMISTRY IN THE CLASSROOM AND SOCIETY: PAST, PRESENT AND FUTURE OF THE FIELD

Submissions Closed
Geochemistry, by its very nature, is interdisciplinary and thus has a key role in demonstrating the interconnectedness of science. This theme includes the topics such as (i) communicating the results of geochemists’ endeavors to students as the scientists of the future and (ii) engaging key stakeholder groups including cross-disciplinary collaborators, the wider public, funders, and policy-makers. Throughout the session, we welcome thoughtful discussion of how these initiatives consider issues of diversity, equity, inclusion, and accessibility, which should be a priority for anyone looking to engage a wide range of stakeholder groups. Specifically, i) building students’ capacity to make connections between the sub-disciplines of geoscience, and with other relevant disciplines, is seen as crucial preparation for the challenges they will face in the workplace. This part of the theme includes the nature and impact of undergraduate research projects, interdisciplinary work-based learning projects, and field-based learning. All initiatives that seek to help students make meaningful connections and that address the question “How are we preparing students to work in interdisciplinary and international teams to address current and uncertain future global challenges?” are welcome. ii) The work of geochemists has huge societal impact, yet many in society would be hard pressed to explain why. We are interested in effective inreach and community building; effective strategies for bringing together geoscience and other disciplines, such as chemistry, astronomy, biology, and data science. We invite sessions that address engaging public audiences in geochemistry, including but not limited to citizen science campaigns, narrative building/storytelling, formal or informal life-long learning initiatives, and the deployment of novel media (e.g., smartphone apps). Sessions also are welcome that address national projects to advise industry or policy-makers, the virtual dissemination of topical issues or publications via the local, national, or global news media.

In order to support broad participation, all abstracts submitted to this Theme are free of charge, and can be in addition to another abstract from the same presenting author in another Theme.
