Fluid Inclusion and Isotopic Characteristics of Molybdenum Deposit in Hexi Village,Weichang County,Hebei Province
摘要
Abstract
Hexi village molybdenum deposit is a porphyry molybdenum deposit newly discovered in recent years.The ore body occurs in quartz monzonite porphyry bodies.Its formation age is 136.6 Ma.The alkali feldspar granite porphyry invaded and destroyed the rock and ore body characteristics of the ore-bearing quartz monzonite porphyry,and its formation age is 129.8 Ma.The mineralization age of the porphyry molybdenum deposit in the study area ranges from 129.8 to 136.6 Ma.The mineralization age of the porphyry molybdenum deposit in the study area ranges from 129.8 to 136.6 Ma.Fluid inclusion studies show that the inclusions are mainly liquid-rich two-phase aqueous solu-tion inclusions.The homogenization temperature ranges from 244.7 to 388.1℃,the salinity ranges from 0.33%to 4.55%,the fluid density ranges from 0.48～0.83 g/cm3,and the homogenization transient pressure ranges from 3.2～24 MPa.The ore-bearing quartz vein is D vein.It was formed in the late stage of quartz monzonite porphyry magmatism.关键词
