However, little research workhas been done on the contents, variation characteristics and significance of halogens in solid ores(rocks). It is found in the study of the Danzhai Hg-Au deposit that (i) variations in the contents ofhalogens and their distribution regularities in solid rocks and ores can shed light on the formation of thedeposit; and (ii) halogens can serve the function of indicator elements in search of buried orebodies. 1 Main characteristics of the ore展开更多
