Our group focusses on the study and characterization on the geological processes that occur in continental environments, in some cases under extreme conditions. These environments which include lakes, caves, soils, springs, wetlands and deserts are very sensible to environmental changes (climate, volcanism, tectonic...) and so their deposits constitute a unique record of the history of the continental areas of our planet. We compare the deposits and processes that occur at present with those archived in the geologic record. Of special interest are some of the carbonate deposits formed very recently in the Canary Island induce for human activity, which are then considered as antropogenic. The research has application to better understand the global change, sinks of CO2 and also some deposits and environments may be used as Mars analogues. The area of work is worldwide (Spain, Chile, Argentine, China...). We have a wide numbers of national and international collaborations. At present we have financial support from MINECO. Our group is also very active in divulgation of science, participating actively in Geolodia and in interviews in the media.
