RE:DecarbonatizationTo make it very simple: Intensely decarbonatized rock is commonly black, carbonaceous, powdery, low density, no reaction to HCl and most characteristics of the host lithology is destroyed. Medium to strong decarbonatization is confined to within the orezones. Here is the exert from the news release, "The bottom 230 metres of SGVC006 encountered black, carbonaceous, debris flows with significant diagentic pyrite exhibiting intense silicification, brecciation and high levels of secondary pyrite." At the end of the day this means....GOLD. Realty
