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 …

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 …

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 …

The theoretical framework of Unconventional Petroleum Geology has been gradually
established along with the rapid progresses in exploration and development of …

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 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 …

Reconstructing historical atmospheric oxygen (O2) levels at finer temporal resolution is a top
priority for exploring the evolution of life on Earth. This goal, however, is challenged by gaps …

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 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 …
