Prediction of parameters of cassiterite-sulfide ore bodies based on the results of sampling of cryogenic oxidation zone

Four morphological types of outcrops on the surface of oxidized sulfide ores, caused by four types of processes of cryogenic and pre-cryogenic oxidation, are described. The main features of these processes that lead to changes in the contents of inert components (such as cassiterite) and in the thickness of vein ore bodies are described. The coefficients allowing to predict the values of parameters of unoxidized ore bodies on the basis of known parameters of the upper part of the oxidation zone are given.
