Geochemistry of Organic Sediments

Geochemistry of organic sediments refers to the study of the chemical composition, distribution, and transformations of organic matter within sedimentary environments, focusing on the interactions between biological processes and geological factors that influence the accumulation and alteration of organic materials over time. This field examines the molecular characteristics of organic compounds and their role in biogeochemical cycles, particularly in relation to nutrient cycling and energy flow in ecosystems.
