Phanerozoic Onset of Massive Continental Weathering

Geophysical Research Letters, Volume 52, Issue 17, 16 September 2025.
Abstract Continental weathering acts as a nexus of global biogeochemical cycles yet its long‐term evolution remains unclear. Here we show that continental weathering may not have operated on a massive scale until the early Paleozoic based on a large‐number data compilation of mudstone geochemistry.

1.38 Ga Four‐Layer Tuff Marker Horizon in North China black Shales as a Chronostratigraphic Boundary for the Pre‐Ediacaran Geological Timescale

Geophysical Research Letters, Volume 52, Issue 17, 16 September 2025.
Abstract Boundaries in the Phanerozoic chronostratigraphic scale are mainly precisely defined and dated, and many correspond to environmental catastrophes induced by the emplacement of LIPs. The pre‐Ediacaran geological timescale is currently subdivided by approximate absolute ages.
