Clay Mineral Interactions and Organic Matter Dynamics
Summary
Clay minerals play a central role in the fate of organic matter across terrestrial and marine systems. Their layered structures and high specific surface areas enable adsorption, intercalation and complexation of organic molecules, thereby governing the preservation, transformation and mobilisation of carbon compounds. Surface charges and interlayer spacing control sorption kinetics, influencing both labile and recalcitrant pools of organic matter. Organomineral associations regulate hydrocarbon generation in shales by stabilising or releasing organic matter during diagenesis, while in marine sediments they enhance long-term carbon burial as organomineral nanocomposites. Advances in spectroscopic imaging and surface analysis have revealed how mineralogy, pore architecture and environmental conditions drive these interactions. Understanding clay–organic dynamics has critical implications for soil fertility, carbon sequestration, water quality and the exploration of unconventional energy resources.

Clay Mineral Interactions and Organic Matter Dynamics publication trend
The graph below shows the total number of articles in clay mineral interactions and organic matter dynamics across all publications each year (not limited to Nature Index journals).
Technical terms
Interlayer adsorption: Uptake of organic molecules into the space between clay mineral sheets, affecting stability and release of organic carbon.
Organoclay complex: A composite formed by physical or chemical association of organic compounds with clay minerals.
Illitization: Diagenetic transformation of smectite or mixed-layer clays into illite, altering pore networks and organic matter release.
Specific surface area (BET): Total surface area per unit mass of a mineral as measured by the Brunauer–Emmett–Teller method, which governs adsorption capacity.

About these summaries
This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
