PhD project title:

Examining the role of estuarine particles in silicate weathering

Project description:

This project aims to find out the profile of Lithium isotopes in Yellow River estuary and understand silicate weathering in estuarine areas. Continental chemical weathering is an important process of moderating the global climate on geological timescales.

Chemical weathering of silicates converts atmospheric carbon dioxide (CO2) to hydrogen carbonate ions, which are transported by rivers into oceans where they precipitate as carbonates. This process leads a negative feedback to global temperature. Thus, investigation of the weathering signal is essential for a better understanding of global carbon cycle and its climatic impact.
