Great Deposits of the World Mount Isa Zn Pb Ag; Cu

Size and ScaleFormation and GeologyReferences and Further ReadingMt Isa is the largest example of a Sedimentary Exhalative or SEDEX deposit. These are formed as hot, metal rich brines percolate through sea floor sediments.160;The figure below demonstrates the scale of Mt Isa in comparison to other SEDEX deposits and the distribution of known Lead Zinc deposits over time. Note that Mt Isa (represented by the blue bar) contains an estimated of 90,000,000 tonnes combined lead zinc (Pb Zn) metaSee more on geologyforinvestorsOnline Service

Primary geochemical anomalies in the Caijiaying Pb Zn Ag

Abstract. The Caijiaying Pb Zn Ag deposits consist of five zones of mineralization occurring in hornblende plagioclase granulite. A lithogeochemical survey was carried out within the area of the ore deposits; very strong primary anomalies of Pb, Zn, Ag, Cd, As, Sb, Hg and B, and weak anomalies of I, Cu, Co and Bi were found.
