Comunidades microbianas endoevaporíticas relacionadas con la precipitación de dolomita en ambiente lacustre salino: Mioceno de la Cuenca de Madrid

Microbial endoevaporite comunities thrivied in a Miocene saline lake where gypsum crystals were precipitate. As a result of both the survival strategies and the metabolic activities carried out by those communities, the gypsum crystals embedding them were intensely corroded and became, in some cases...
