O papel da Zona de Cisalhamento Juzbado: Penalva do Castelo na intrusão de granitos variscos tardi-pós- D3 da região de Viseu (Zona Centro-Ibérica)

Abstract

A intrusão do maciço de Cota-Viseu teve lugar numa área tectónicamente complexa, onde tem lugar a terminação ocidental da Zona de Cisalhamento de Juzbado - Penalva do Castelo (ZCJPC). O granito inclui-se no grupo dos granitóides variscos tardi- pós- D3 e faz parte de um batólito zonado que ocupa uma grande extensão na Zona Centro-Ibérica. O granito de Cota-Viseu corta a ZCJPC e não apresenta evidências de deformação no estado sólido. Contudo, os dados obtidos através do estudo da anisotropia de susceptibilidade magnética e a interpretação estrutural regional, indicam que a ZCJPC parece ter exercido um forte controlo na localização das vias de ascensão do magma e na criação do espaço necessário para a instalação do corpo intrusivo.

The Cota-Viseu massif is part of a late-post-tectonic composite batholith that occupies a large area in the Central Iberian Zone. It is emplaced in a tectonically complex area located at the western termination of the Juzbado - Penalva do Castelo Shear Zone (JPCSZ). The Cota-Viseu granite intrudes the JPCSZ and shows no evidence of solid-state deformation. However, the measurements of magnetic fabrics in the granite and the structural regional interpretation suggest that the JPCSZ controlled the location of the magma feeders and opened space for granite emplacement.
