WebLithocaps are subsurface, broadly stratabound alteration domains that are laterally and vertically extensive. They form when acidic magmatic-hydrothermal fluids react with wallrocks during ascent towards the … Web1 jan. 2010 · Abstract. Porphyry Cu systems host some of the most widely distributed mineralization types at convergent plate boundaries, including porphyry deposits centered on intrusions; skarn, carbonate-replacement, and sediment-hosted Au deposits in increasingly peripheral locations; and superjacent high- and intermediate-sulfidation …

Ar-gentite, the principal hypogene silver mineral, inverted to acanthite and is associated spatially with disseminated barite (Steele 1996).
