The principle, application, and prospect of using the uranium comminution age to indicate the catchment erosion depth
Catchment erosion not only shapes various landforms of the earth’s surface but also affects the rates of chemical weathering and CO2 absorption by controlling the exposure of rock fragments, and thus acts as a re...

The hydrogen and oxygen isotopic compositions of hydroxyl in clay mineral from a weathering profile: New proxies for paleo-climate change?
Recent studies suggest that the hydrogen and oxygen isotopic compositions of clay minerals can indicate paleoclimate. Here, we report mineralogy and stable isotopic records (δD and δ18OOH) of a weathering profile...
