The accumulation of oxygen is one of the most important characteristics that distinguish
Earth from other planets in the solar system, which is also considered to be the key factor …

The study of well-preserved organic matter (OM) within mineral concretions has provided
key insights into depositional and environmental conditions in deep time. Concretions of …

The relationship between oxygen and evolution of early eukaryotes including algae and
primitive animals in geological history has been debated, partly due to the varying estimates …

摘要碳循环是生命改造地球的最主要途径. 海洋是地球上最大的活跃碳库, 其储碳-
释碳的异常波动对地球表层系统演化具有革命性影响. 然而, 中元古代无机碳同位素的相对稳定 …

Marine carbonate fabrics are intrinsically related to ocean chemistry, physical processes and
biological activity. Molar tooth structure (MTS), a globally distributed structure in Proterozoic …

Organic matter (OM) in shales occurs as nanometer-sized intercalations with clay minerals
that are termed as clay-organic nanocomposites; however, the OM occurrence in …

Early diagenesis of marine organic matter dramatically impacts Earth's surface chemistry by
changing the burial potential of carbon and promoting the formation of authigenic mineral …

Oxygen availability is crucial for the evolution of eukaryotes in geological history. However,
the evolution of mid-Proterozoic oceanic–atmospheric redox conditions remains heavily …

Marine red beds (MRBs) are common in sedimentary records, but their genesis and
environmental implications remain controversial. Genetic models proposed for MRBs …

Current research on diagenesis and its evolution focuses mainly on sandstone reservoirs.
