DOI: 10.1016/j.gca.2020.04.018
Abstract: Abstract The behavior of molybdenum (Mo) isotopes during chemical weathering was investigated through analysis of saprolite and soil samples from two weathering profiles developed on Neogene basalts of Hainan Island in southern China. The Penglai… read more here.

DOI: 10.1016/j.jasrep.2017.11.025
Abstract: Abstract Subaerial weathering is a taphonomic process that affects many archaeological and paleontological bone assemblages and is characterized by surface bleaching, loss of organic component, and progressive cracking and splintering of the bones. Although the… read more here.

DOI: 10.1029/2020pa003909
Abstract: The development of the South Asian monsoon (SAM) and Himalaya‐Tibetan Plateau uplift were closely intertwined with some studies suggesting that uplift initiated the monsoon whereas others link tectonics with monsoon‐controlled exhumation. Silicate weathering controls atmospheric… read more here.

DOI: 10.1038/s41598-019-40819-9
Abstract: As bedrock weathers to regolith – defined here as weathered rock, saprolite, and soil – porosity grows, guides fluid flow, and liberates nutrients from minerals. Though vital to terrestrial life, the processes that transform bedrock… read more here.

DOI: 10.1073/pnas.1711862115
Abstract: Significance Estimates of seawater Li isotopic composition at the Permian–Triassic boundary (PTB) reveal extremely light seawater Li isotopic signatures accompanying the most severe mass extinction in the history of animal life. Theoretical modeling indicates a… read more here.

DOI: 10.1126/science.add2922
Abstract: Earth’s climate may be stabilized over millennia by solubilization of atmospheric carbon dioxide (CO2) as minerals weather, but the temperature sensitivity of this thermostat is poorly understood. We discovered that the temperature dependence of weathering… read more here.
