Geochemical Anomaly and Metallogenic Prospect Analysis of Buzicun Area in Gerze County, Tibet
摘要
Abstract
The Bangong Co-Nujiang metallogenic belt is one of the most important metallogenic belts in Tibet.Its geochemical characteristics of Longbakangdong-Kangjia section at Buzicun village are analyzed based on the result of 1∶50 000 stream sediment survey, including distribution and anomaly characteris-tics of ore-forming elements on the surface, and the characteristics of anomaly element combination.The results show that metal anomaly occur in combination of multiple metal elements, and the highest anomaly is Au-Cu combination, the second is front elements combination of As-Sb-Ag-Cd-Pb, then rear element combination of Bi-W-Mo.The anomaly areas of front elements, ore-forming elements, and rear elements are distributed from west to east, and the halos have good zonation, suggesting that there may be a por-phyritic type Cu-Au deposit in study area, and Longbakangdong-Kangjia anomaly area may be a potential area for prospecting large copper-gold deposit.关键词
