Aplicación de los isótopos estables en el estudio de los dipósitos minerales (Application of stable isotopes in the study of ore deposits).

Lecturer:Dr. Esteve Cardellach López

Date: Thursday  March the 5^th, 15:00-17:30h

Place:Room 4

Abstract: The talk began with a brief overview, as a reminder, on the theory of isotopic equilibrium systems most frequently applied to the study of mineral deposits, namely isotopes of S, C, O and H. Dr. Cardellach pointed out the particularities and the information that provides each of these isotopes and isotopic pairs, focusing on its application for the identification of the origin of mineral fluids.

In addition to theoretical considerations, Cardellach exposed a number of real examples applied to the study of deposits. Some of these examples included: wolframite deposits of Panasqueira (Portugal), Pb-Zn deposits associated to diapirs in the Basque-Cantabrian Basin, Pb-Zn deposit MVT type of San Vicente (Peru), Zn-Pb-Ag deposit Sedex type of HYC McArthur River  (Australia) and veins of Ba-F-Pb-Zn of Atrevida vein (NE of the Iberian Peninsula, Spain).

Biografical summary:Dr. Cardellach is former professor and researcher of Mineralogy and Mineral Deposits at the Geology Department (Universitat Autònoma de Barcelona (UAB)). Great part of his research has been focused on the origin and evolution of mineral fluids. During his professional career has made research stays to Durham University and Yale University, where he worked on the geochemistry of stable isotopes.

Recently he has been principal investigator on several research projects, the latest of which dealt with the study of epithermal Au deposit at Cerro Quema, Panama. Currently, Cardellach is involved as researcher in a project led by the Universidad de Huelva (Spain) on Black Shales and massive sulfide deposits.
