Geology and gravity modeling of the Logrosán Sn–(W) ore deposits (Central Iberian Zone, Spain)

Sn–(W) granite-hosted ore deposits are characterized by the occurrence of pegmatites, stockworks and quartz veins within a granitic cupola and its surrounding host-rocks. A regional exploration tool for these deposits consists of targeting syn- to late-orogenic specialized S-type hidden shallow granites by geophysical methods. However, gravity as a tool for “brownfield type” exploration in a mature granite-related ore setting has not been widely...
