...Andrea Brogi; Giovanna Giorgetti Abstract This paper deals with a structural and petrographic study carried out on key outcrops belonging to the Tuscan Nappe exposed in the Colline Metallifere region (Montieri-Poggio Prugnoli). Here, the Tuscan Nappe was affected by polyphase deformation...

... of the Colline Metallifere region (Tuscany). A particular aim of this study was to constrain the deformation pattern accompanying the genesis and the emplacement of the Pliocene (4.9-4.4 Ma) Gavorrano monzogranite intrusion. A N-S trending right-lateral strike-slip fault zone, constituted by an array...

... in the coastal area, Sassetta in the Toscana marittima, Poggio Ritrovoli in the Colline Metallifere, and Rigomagno south to the Chianti Mountains. Because of the quality of the exposures, the research methodologies provided two levels of detail. First, geological surveys, based on S/M ratio lithofacies, produced...

..., Ba–Hg enrichment is a feature common in alteration in VMS throughout the Tally Pond belt (e.g., Collins 1989 1 ). Metalliferous mudstones and detrital shales from the Tally Pond belt outside Lemarchant have Ba values that are up to 3792 ppm and Hg contents up to 8790 ppb ( Fig. 14C ). The Bell...

...) and iron later ( Tylecote, 1987 ). Close to the VIII century B.C., Tuscany (central Italy) became an important mining and metal processing site of the western Mediterranean basin. Economically important concentrations of Cu-Pb-Ag sulphides were present in the mainland (Colline Metallifere mining district...

In particular, we examine the requirement for the flow of a large volume of metalliferous brine to transport...
