Abstract
The Aguapei Mobile Belt in the Southwestern portion of the Amazon Craton, Pontes e Lacerda region, state of Mato Grosso, Brazil, forms an approximately 200km long NW trending regional structure that is made of folded metasedimentary rocks of the Aguapei Group, which cover basic-ultrabasic rocks with chemical sedimentary rocks of the Rio Alegre Terrane, and granitic rocks of the Santa Helena Terrane. Based on tectonic regime, predominant kinematics, and associated structures, the Aguapei Mobile Belt has been divided in four domains. From SE to NW they were named: transcorrent tectonic domain, low-angle contractional tectonic domain, symmetric folded domain, and brittle and tilted domain. Important gold mineralizations are associated with rocks from the Fortuna Formation in some of these domains. The most important are: the Sao Vicente Mine in the symmetric folded domain, Lavrinha Region deposits in the low-angle contractional tectonic domain, and Pau-a-Pique Deposit in the transcorrent tectonic domain.
