Abstract The Cambrian Period is the first period of the Phanerozoic Eon and witnessed the
explosive appearance of the metazoans, representing the beginning of the modern earth-life …

The ocean‐atmosphere system is typically envisioned to have gone through a unidirectional
oxygenation with significant oxygen increases in the earliest (ca. 635 Ma), middle (ca. 580 …

Abstract The Early Cambrian Late Stage 2 to Stage 3 (526–514 Ma) was characterized by
the peak of the Cambrian Explosion and a large-scale global transgression that resulted in …

Pore structure is of great importance in the occurrence of shale gas. In this study, pores in
shale samples from the Lower Silurian Longmaxi and Lower Cambrian Niutitang shales in …

Oil and gas discoveries within Proterozoic-Cambrian strata and the majority of shale gas
production occurs in relatively stable tectonic regions and characterised by moderate …

Abstract The Ediacaran–Cambrian transition is a critical interval marking drastic biological,
oceanic and geochemical co‐evolutions in geological history, but it is poorly constrained …

Given the high oxygen demands of complex metazoans, a sound understanding of marine
redox conditions is essential to reconstruct the factors that lead to the dramatic increases in …

Oceanic redox changes may be a key environmental trigger for the “Cambrian explosion”.
However, a hypothesized predominantly oxygenated early Cambrian ocean, inferred from …

The origin of widespread organic-rich shales on the early Cambrian Yangtze Platform of
Nanhua Basin (South China) has been attributed to high primary productivity. To test this …

The organic-rich sediments were widely deposited over the entire Yangtze Block during the
Early Cambrian (late Nemakit-Daldynian to Botomian). In the mid-upper Yangtze region …
