Geochemical Characteristics of Primary Halos and Prospecting Significance of the Qulong Porphyry Copper–Molybdenum Deposit in Tibet

The Qulong porphyry copper deposit in Tibet is located the Tethis–Himalaya metallogenic domain, one of three major domains world. At present, mining area mainly used for surface mining. depth revealed by drilling project less than 2 km. potential deep resources unknown. Based on an analysis geochemical characteristics primary halos around No. 16 prospecting line, extension discussed this paper. Studies show that elements are Cu and Mo; near-ore halo Co, Au, Ag, W; supra-ore Pb, Zn, Mn, As; sub-ore Sn Bi. According to Gregorian’s zoning index barycenter method, exploration line from shallow Mn–P–Pb–Ni–Zn–V–As–Hg–Co–Au–Cu–W–Ag–Mo–Sb–Sr–Cd–Sn–Ti–Bi. This sequence has a distinct “reverse” feature, indicating there may be blind ore body mine. parameter evaluation based element content contrast coefficient suggests hidden deep. relative hydrothermal mineralization center position section below north side borehole ZK1601-1 middle section. erosion model shows bottom engineering control tail body, certain amount part. ideal superimposed reflects trend 16th inclined as whole; fluid flows southern side, part northern downward trend.
