Title of Project

Apatite as an indicator mineral in mineral exploration studies

Project details

Apatite is a common accessory mineral in both magmatic rocks and many types of base metal deposit.  It has strong potential as an indicator mineral in mineral exploration studies due to its widespread occurrence, its ability to accept a wide variety of trace elements into its crystal structure and its ability to provide reliable U-Pb and fission-track age information.  However the lack of a comprehensive database on apatite compositions in potential source rocks remains a stumbling block to the routine application of apatite geochemistry as an indicator mineral in mineral exploration studies.  This project will develop the link between apatite trace-element chemistry and parent-rock composition by analysing apatite - parent rock pairs sampled from both ore deposits and igneous rocks of diverse compositions.

Postgraduate personal details

Graduated in Geology and M.Sc. in Geochemistry by UFRGS – Federal University of Rio Grande do Sul – Brazil. From 2004 to 2006 I participated on the project “Genetic and prospective models of the Pitinga mine” as a scholarship undergraduate. Also as an undergraduate I did research on the galena hydrothermal deposits in the city of Amaral Ferrador - Brazil. From 2008 to 2010 I worked as an intern at the CPRM – Geological Survey of Brazil, on the project “Geochemical Prospecting in the East Dom Feliciano Belt – Brazil”. My master’s research was focused on the characterization of hydrothermal Au Porphyry Deposits in Yarumalito, Colombia.
