Research and Technical Experience:

Igor Figueiredo is a geologist with a specialization in geochemistry, focusing on trace elements, Sr-isotopes, and the geochronology of Rb-Sr using LA-ICP-MS. He completed his MSc at the Federal University of Ouro Preto, where he developed new tools for data reduction, specifically TE Saturn and Sr Saturn as part of the Saturn Project. These tools have been instrumental in refining the analysis of trace elements and Sr-isotopes obtained through LA-ICP-MS.

During his MSc research, Igor applied these data reduction tools to investigate the origin of diagenetic and hydrothermal fluids influencing the formation and diagenesis of Pre-salt carbonates. His work provided new insights into the role of these fluids during the rifting of West Gondwana and the subsequent opening of the Central South Atlantic, advancing the understanding of early Atlantic Ocean formation.

Skills and Interests:

Igor is highly skilled in developing software for data reduction and in the application of geochemical methods to solve complex geological problems. His strong foundation in Sr-isotope analysis and trace element geochemistry is complemented by his analytical precision and ability to innovate in laboratory settings. Igor is passionate about advancing methods in isotope geochemistry, particularly in refining analytical approaches that enhance the reliability of geochronological data.

Current Research:

Igor is pursuing his PhD at the Open University in the UK, where he is focused on advancing the Rb-Sr dating method in micas using LA-ICP-MS. His research tackles key challenges related to the precision and accuracy of in situ Rb-Sr geochronology, including validating community-agreed reference materials, understanding crystallographic effects on data quality, and optimizing analytical protocols.

Through his work, Igor aims to establish a new framework that effectively links mica ages to geological processes within shear zones. This framework promises to improve the understanding of deformation events and the thermal history of geological formations. Igor’s technical expertise in geochemistry, combined with his innovative approach to data reduction and his ongoing PhD research, positions him as a valuable contributor to the fields of Rb-Sr geochronology, isotope geochemistry, and the study of fluid-rock interactions in complex geological systems.
