Abstract

Arenitos e conglomerados foram encontrados intimamente associados a rochas vulcânicas alcalinas, em contato direto com o embasamento cristalino, a cerca de 12 km ao nortedo Maciço Alcalino de Poços de Caldas. As observações petrográficas e de campo indicaramque os sedimentos conglo meráticos estão geneticamente relacionados ao tectonismo que afetou o referido Maciço.
