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.
