Fluid Inclusion Study on the Aikengdelesite Mo (Cu)Ore Deposit,Eastern Kunlun
摘要
Abstract
Aikenglesite Mo (Cu)deposit,a porphyry molybdenum (copper)deposit newly found in Eastern Kunlun in recent years,is located in the east of Kunnan compound splicing belt.The ore bodies are found in the granite porphyry as well as the outside broken monzonitic granite.The research of fluid inclusion in veined ore-bearing quartz and metallogenic characteristics show that the mineralization process can be divided into 4 stages:oxide stage (Ⅰ),pyrite-pyrrhotite-quartz stage (Ⅱ),molybdenite-polymetallic sulfide stage (Ⅲ)and carbonatite stage (Ⅳ).The types of fluid inclusions mainly include gas-liquid two-phase inclusions and halite-bearing three-phase inclusions.The fluid belongs to H 2 O-NaCl system and the range of homogeneous temperature, salinity and density are 150-280 ℃,2-30 wt% NaCl and 0.76-1.1 6g/cm3 .The major metal sulfides are formed in low temperature (mainly concentrated on 200 ℃).After all,it is calculated that the metallogenic depth from middle to late mineralization stage is 1.2-3 km,and the ore-bodies are well preserved.关键词
