High pressure and HP-HT behaviour of lizardite and chlorite

Layered minerals such as lizardite and chlorite are believed to be possible water-carrier in the deep Earth crust. However, the high-pressure behaviour of layered minerals is still poorly constrained. This is due to several factors, including the layered nature of these minerals that often result in the acquisition of low-quality single crystal data. Because of that, we selected several single crystal of both specimens, collected from renowned outcrops. The main target of this proposal is to investigate the structure evolution and the high-pressure behaviour of lizardite and chlorite in order to better constrain their PT stability range.
