摘要

•The Lavra Velha deposit represents a new gold-rich IOCG mineralization at the São Francisco Craton.•The gold mineralization is associated with a hydrothermal breccia system with co-existing iron oxides and sulfides.•IOCG mineralization is related to the Rhyacian period of the northern São Francisco Craton.•Mineralization is marked by decreasing temperatures from the bottom to the top of the deposit.
