Mexico
Field Context :
There are many alkaline lakes hosting microbialites in the Trans-Mexican volcanic belt. These lakes have varying chemistries and therefore we can study the links between lake chemistry, microbial diversity and microbialite chemistry and mineralogy.

Field Goals :
We aim at assessing the links between the chemistry of lakes, the mineralogical and chemical composition of microbialites and their microbial diversity. We also work on microbialites forming in seasonally anoxic water.

Implemented actions :
In collaboration with scientists at UNAM, Paris-Saclay, IPGP and Université de Bourgogne, we travel to Mexico once a year or every two years. We sample water, sediments, microbialites. Currently, this research is performed in the frame of the ANR Microbialite. Moreover, Jeanne Caumartin received a PhD grant by the Sorbonne University program Interface pour le vivant to work on these microbialites.
