The long history of life on Earth has unfolded as a cause-and-effect relationship with the
evolving amount of oxygen (O2) in the oceans and atmosphere. Oxygen deficiency …

Redox-sensitive trace metals have been used extensively as geochemical proxies to infer
the redox-status of marine sediments at the time of their deposition, and by extension, the …

随着非常规油气资源工业化勘探开发的快速发展, 非常规油气地质学理论体系逐步建立,
迫切需要创新构建非常规油气沉积学理论. 通过简要概述非常规油气沉积学的基本内涵 …

Eukaryotic life appears to have flourished surprisingly late in the history of our planet. This
view is based on the low diversity of diagnostic eukaryotic fossils in marine sediments of mid …

Deep and ancient strata are significant successor fields for future oil and gas exploration.
Recently, a unit of thick high-quality interglacial black rock series was discovered between …

Mapping the history of atmospheric O2 during the late Precambrian is vital for evaluating
potential links to animal evolution. Ancient O2 levels are often inferred from geochemical …

The emergence and expansion of animal life on Earth represents a dramatic shift in the
structure and complexity of the biosphere. A lack of firm constraints on surface oxygen levels …

The secular trend of seawater strontium isotope ratio (87 Sr/86 Sr) reflects changes in the
relative contributions of continental versus mantle reservoirs to ocean composition, and …

The emergence and expansion of complex eukaryotic life on Earth is linked at a basic level
to the secular evolution of surface oxygen levels. However, the role that planetary redox …

The global biosphere is commonly assumed to have been less productive before the rise of
complex eukaryotic ecosystems than it is today. However, direct evidence for this assertion …
