The Monte San Nicola section (Sicily) revisited: A potential unit-stratotype of the Gelasian Stage
2022
The Monte San Nicola area (Southern Sicily) offers a spectacular exposure of open-marine sediments that were employed in 1998 for defining the Global Stratotype Section and Point (GSSP) of the Gelasian Stage (Upper Pliocene). After the lowering of the Pliocene/Pleistocene boundary to ca. 2.6 Ma in 2010, the Gelasian GSSP has been redefined as the base of both the Pleistocene Series and the Quaternary Period, which increased its importance and visibility within the scientific community. However, documentation on the Monte San Nicola reference section is still sparse. In the light of its renewed status, we decided to undertake a complete revision of the Gelasian Stage in its type area, in ord…
GIS-based methodology for mapping and modeling microbialite deposits in high mountain lakes and wetlands of Central Andes (Catamarca, Northwestern Ar…
2022
Modern microbialites in Argentina's Puna (Central Andes) are considered a reliable tool for understanding the evolution of early life on our planet and developing strategies for detecting life on Mars. The morphological, structural and geochemical variations in these deposits, together with their distribution and architecture, are some of the most important parameters for understanding and characterising them. However, the lack of appropriate cartography and/or the high price to access it, added to the complex geological and geomorphological context in this region, complicate a traditional mapping on a good scale of detail. This paper presents a GIS-based methodology for a detailed mapping …
Caracterización Geoquímica y Petrográfica del 'Gabro de La Corona', Municipio de La Victoria, Boyacá - Colombia
2004
Se denomina "Gabro de La Corona" al cuerpo ígneo básico conocido en la literatura como Intrusión de La Corona (Quebrada El Cedro), de acuerdo con la litología dominante y su localización geográfica en las cercanias del caserío de La Corona en el Municipio de La Victoria Departamento de Boyacá. La sucesión arcillosas del Grupo La Palma, considerada equivalente a la Formación Simití, en la estratigrafía del Valle Medio del Magdalena, se encuentra intruída por el cuerpo básico que regionalmente se puede considerar como un silo, compuesto por rocas clasificadas petrograficamente como leucogabros, leucogabros hornblendicos, gabros, gabros horbléndicos y gabros piroxénico-horbléndicos. Geoquímica…

Confirming Human Antiquity: Spain and the Beginnings of Prehistoric Archaeology
2013
During his first visit to Spain in 1862, Louis Lartet together with Edouard de Verneuil and the Spanish mining engineer Casiano de Prado visited the San Isidro archeological site in Madrid. There they obtained a worked silex tool, which the former two then described and illustrated in the Bulletin de la Société Géologique de France. Three years later, Edouard Lartet together with Henry Christy and Hugh Falconer designed a project to extend the exploration in the field of prehistoric and archaeological works to the Iberian Peninsula. After Christy¿s death at the beginning of 1865, and Edouard¿s illness, it was Louis Lartet who undertook the research program of Prehistoric Archaeology South o…
