Manto style mineralisation
WebDuring early Permian time, the continental blocks moved together producing subduction zones with associated magmatic arcs. Numerous porphyry style mineralisation … WebManto-style mineralisation is generally structurally controlled and stratabound within permeable host rock. In the example modelled here, a thrust fault has superimposed prospective lithologies against younger, barren rocks. Mineralisation was modelled as a stack of stratabound lenses against the fault.
