The Holocene volcanism at El Hierro consists of basaltic monogenetic volcanic fields associated with the three rift systems present on this island. In this work, we report preliminary petrological and geochemical data of Holocene lava flows belonging to the WNW-striking rift. Sampling was focused in three zones: Orchilla, Verodal-Sabinosa, and Tang...
The Neoproterozoic Bou Azzer ophiolite in the Moroccan Anti-Atlas Panafrican belt hosts numerous chromitite orebodies within the peridotite section of the oceanic mantle. The chromitites are strongly affected by serpentinization and metamorphism, although they still preserve igneous relicts amenable for petrogenetic interpretation. The major, minor...
Ultramafic-hosted volcanogenic massive sulfide deposits (UM-VMS) located in the Havana-Matanzas ophiolite (Cuba) are the only known example of this type of mineralization in the Caribbean realm. UM-VMS from Havana-Matanzas are enriched in Cu, Ni, Co, Au, and Ag. The mineralization consists of massive sulfide bodies mostly composed of pyrrhotite and...
The Habana-Matanzas ophiolites (western Cuba) host several hydrothermal ultramafic-hosted Cu-Au-Co rich massive sulfide deposits (e.g. Loma Majana and Salomón). The ore mineralogy of these deposits consists of pyrrhotite, pyrite, and chalcopyrite, with minor Co-Fe-Ni arsenides/sulfarsenides (mainly safflorite and cobaltite), gold (electrum), and re...
We are a research group of earth scientists, with the ultimate goal to develop research and teaching in mineralogy and ore deposit models.
Skarn formation results from the interaction between silicate melts or high-temperature hydrothermal fluids and carbonate host rocks. Skarns consist of calc-silicates and commonly host economic Cu, Zn-Pb-Ag, Au, Sn, W or Mo mineralization. Skarn deposits formed in the vicinity of the causative magmatic bodies are called proximal. In the contrary, if there is no clear relationship with an intrusive body, the skarns are called distal. Distal skarns are dominantly Zn or Pb-Zn-Ag and in particular cases may host Fe mineralization. This project is focused on the understanding of the geological and fluid processes leading to the formation of distal skarn deposits, studying a suite of three systems with different metal endowment but sharing common geological features – the Madan Pb-Zn ore field (central Rhodopes, Bulgaria), the Calamita Fe-skarn (Elba Island, Italy), and the Megalo Livadi Fe ± Pb-Zn-Cu skarn (Serifos Island, Greece).
http://caribbeanlithos.ub.edu/ CALOR is an international research group whose investigation focuses on a multidisciplinary approach to the understanding of the processes and environments in which the Caribbean plate formed and evolved. We investigate the magmatic, metamorphic and ore-deposit records of the region. They are key for the understanding of Caribbean-North America and -South America plate interactions. The geological development of the Caribbean region is largely controlled by a number of subduction zones that formed along its margins after Pangea's break-up during the Jurassic.
