西藏自治区措勤县日阿布洗铜多金属矿床地质特征及成因类型
Geological characteristics and genetic type of Riabuxi copper-polymetallic deposit in Coqen county,Tibet
摘要
Abstract
The Riabuxi copper-polymetallic deposit in Coqen county,Tibet,is located in the northern margin of the Gangdise porphyry-type copper metallogenetic belt.The host rocks is the late Himalayan granitic-porphyries which are wholly mineralized.The copper-polymetallic deposit is occured at the contact zones of the porphyries and structural altered rocks.Our study reveals that the ore-bearing porphyries exposed at the surface are only apophyses and dikes,an intense erosion did not take place,indicating a benefit potential for discovering deep-seated porphyry deposits.Verified by deep drilling and surface trenching,it is found that the variation coefficients of grades and thicknesses along strikes and dips of ore bodies are small and associated component contents are relatively great.A preliminary estimate shows that metallogenic materials were originated from the late Himalayan first stage granite-porphyry intrusions,and the deposit belonging to a porphyry-type copper deposit.关键词
