... of platinum deposit which is broadly comparable with some epithermal gold deposits. The ore fluid was highly oxidized with a low salinity and generated extensive replacement of feldspar in the wall rocks. Increase in pH generated by wall-rock reactions is seen as an important mechanism in Pt precipitation...
