Porphyry Metallogenic Regularity and Prospecting Direction in Chigou Region of Shanyang County, Shaanxi Province
摘要
Abstract
There exist many small intrusions in Chigou region, Shanyang county, Shaanxi province.The magmatic rocks distribute to North-East direction in little rock plants or branches, belong to Yanshan epoch, high levels of potassium and calcium alkaline series Ⅰ-typed granite, with porphyritic structure.There have porphyry copper deposit, porphyry molybdenum, skarn type copper, tectonic altered rock type gold deposit of four kinds of mineralization, which related to magmatic activity of Yanshan period in Chigou region.Alteration, geochemical anomalies and mineralized body show zonal distribution surrounding porphyry intrusion.It developed molybdenium, copper, and gold mineralization in turn from intrusion to outside, that composed of porphyry-typed, skarn-typed, and hydrothermal solution-typed copper, gold, and molybdenium metallogenic series, rock-forming and ore-forming happened simultaneously, and appears obvious regularity of porphyry metallogenesis.No.Ⅰ rockbody among these 7 rockbody groups is the main intrusion, Inside and at the edge of the No.Ⅰ rock mass is main position of molybdenum mineralization, outward emerges copper mineralization and the golden mineralization,meanwhile, the zoning of mineralization is the same as that of intrusion lithology, wallrock alteration, and metallogenic geochemistry.It concluded that the west and south periphery of No.Ⅰ rockbody should be another place for copper enriching.Through deep drilling control, it is expected to find copper orebody with certain industrial value in the site.关键词
