This work seeks to characterize the Capinha granite (CG), understand its spatial and genetic relationship with the host Peroviseu\u2013Seia (PS), Belmonte\u2013Covilh\u00e3 (BC) and F\u00e1guas granites, and evaluate its metallogenic potential. To achieve these goals, a multidisciplinary approach was undertaken, including field work and identification of the petrography and microstructures, whole rock geochemistry and anisotropy of magnetic susceptibility. Four distinct and independent differentiation trends were identified in the granites, namely, PS, BC, Fr\u00e1guas and CG. The PS and BC played a role as host rocks for the W and Sn mineralizations. The Fr\u00e1guas granite is anomalous in Sn and spatially related to the Sn\u2013Li mineralizations, while the CG is anomalous in W and spatially related to W\u2013Sn mineralizations. The post-tectonic CG is a peraluminous ilmenite-type whose ascent and emplacement were tectonically controlled. The Capinha magma used the intersection between the 25\u00b0 N and 155\u00b0 N strike\u2013slip crustal scale faults for passive ascent and emplacement during the late-Variscan extensional phases. The magnetic fabric was drawn using an asymmetric tongue-shaped laccolith for CG. CG experienced two brittle deformation stages that marked the maximum compressive rotation from NE\u2013SW to NNW\u2013SSE.<\/span><\/div>\n<div><span style=\"font-family: arial, helvetica, sans-serif;\">Read the full article <a href=\"https:\/\/doi.org\/10.3390\/min10060557\">here<\/a>.<\/span><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Ana Gon\u00e7alves, Helena Sant\u2019Ovaia, Fernando Noronha The Fund\u00e3o\u2013Serra da Estrela\u2013Capinha (FSEC) region is characterized by peraluminous to metaluminous Variscan granites intrusive in a complex and thick metasedimentary sequence.
