- Pluton emplacement in a releasing bend in a transpressive regime: the arrozal granite in the Paraíba do Sul shear belt, Rio de Janeiro Alexis R. Nummer Rômulo Machado Nolan M. Dehler Multidisciplinaria (Ciencias Naturales y Exactas) bend releasing emplacement transpression Arrozal Granite The Arrozal Granite, situated in the southwestern region of the State of Rio de Janeiro, has a granitic to granodioriticcomposition. It contains a strong mylonitic foliation along its border, passing gradually to a well-developed magmaticfoliation towards its center. Structural analysis indicates that the Arrozal Granite was emplaced along the Além-ParaíbaShear Zone in a dextral transpressive tectonic regime. A regional shift of the trend along this shear zone from NESWto EW, observed in the area, is interpreted to be casually related to the creation of space for the emplacement of thegranite. Our data indicate that releasing bends may have played an important role for space generation during theemplacement of the Arrozal Granite and other plutons 2007 artículo científico 0001-3765 https://www.redalyc.org/articulo.oa?id=32779211 en http://www.redalyc.org/revista.oa?id=327 Anais da Academia Brasileira de Ciências application/pdf Academia Brasileira de Ciências Anais da Academia Brasileira de Ciências (Brasil) Num.2 Vol.79
