摘要

西藏努日矽卡岩-斑岩铜多金属热液矿床位于西藏冈底斯东段南缘,具有较大的成矿规模和独特的铜钨钼矿化组合。通过在地表利用便携式光谱仪采集岩石矿物的可见光-短波红外波段光谱,分析认为主要存在蚀变矿物绢云母、绿泥石、绿帘石、高岭石、蒙脱石、黑云母、硬石膏、方解石和地开石等。根据蚀变矿物光谱在2200nm和2250nm吸收波段的迁移趋势,确定了绢云母和绿泥石分布规律及矿区中部近北北东向为热液中心位置,对于进一步的矿产勘查具有重要的意义。
Nuri Cu polymetallic ore locates in south rim of Eastern of Gangdise in Tibet. It is presented for larger metallogenic scale and special mineralized combination. From measuring the spectral of rock and mineral using SVC portable spectrograph, some main altered minerals, such as muscovite, chlorite, epidote, kaolinite, montmorillonite, biotite, anhydrite, calcite and dickite and so on. According to altered mineral spectral wavelength changes in 2200 nm and 2250 nm position, distribution of muscovite and chlorite is display and the epithermal center of NNE in the deposit center is considered. The result is very important meaning for mineral prospecting.
