Magnetotelluric images of Paleoproterozoic accretion and Mesoproterozoic to Neoproterozoic reworking processes in the northern São Francisco Craton, central-eastern Brazil
Precambrian Research(2019)
摘要
•Electrical structure of the northern São Francisco Craton derived from MT soundings.•Resistive and conductive crustal blocks indicate a Paleoproterozoic accretion system.•Mesoproterozoic to Neoproterozoic fluids and melts reworked the craton lithosphere.
