Abstract

The latitudinal distribution of continental masses and mountain chains is a key element in the paleoenvironmental reconstruction of the Ediacaran-Cambrian times. However, there is a scant paleomagnetic database for this time interval, and the few poles available are ambiguous providing completely different directions for similar ages. Besides the unconstrained latitude of the blocks, the age and evolution of the mountain chains is also undetermined along most of the Brasiliano-Panafrican belts. In this project we intend to better define the position and evolution of part of the Araçuai orogeny combining paleomagnetic data in the post-collisional intrusions, SIG-based paleogeographic reconstructions and a compilation of geochronological and thermochronological data from SE Brazil. This project is part of the Fapesp Thematic Project 2016/06114-6. (AU)
