Research activities:
Most of my research has focused on solving geochemical problems, following different lines of research related to sedimentary materials and also of igneous origin.

Regard to sedimentary materials, studies in El Soplao cave (Cantabria), enabled us to describe a new type of rock (espeleo-manganese stromatolites), unknown so far. Moreover, within these new rocks we have found the best fossilized microbes in the manganese oxides of the world and also a new mineral species (zacaggnaite-3R). We have recently published the results of geomorphological study of the El Soplao cave, supported by paleomagnetic and geochronology data of these same espeleo-manganese stromatolites. The last publication establishes chemical patterns in formation of aragonite and / or calcite in the cave, necessary for paleoenvironmental reconstructions based on speleothems. Using elemental and isotopic chemistry, we have published the paleoenvironmental results of microbialites in microbialites that cover bivalve from continental jurassic materials of Asturias (Spain).

Regard to igneous materials, the study of meteorites has expanded the knowledge of some specimens fallen in Spain, such as Reliegos and Villabeto de la Peña. In 2013 we classify the last spanish iron meteorite (IAB complex: Retuerta del Bullaque). The geochemical study of Torre de Moncorbo (Portugal) fulgurite (rock formed from a lightning strike) establishes guidelines in fusion of granitic materials from lightning strikes.

Much of the work time have dedicated to the dissemination of the main scientific results obtained during the investigation. For this I used different means both written (articles and books), and audiovisual (documentaries), participating in various proposals for popularizing science (Science Week, Science Fair, Researchers' Night, Geolodía, etc.), the creation of workshops, exhibitions and development of excursions, courses and seminars, within the framework of the Mining Museum.
