Preliminary Analysis for Ore-Controlling Conditions of Shuangyangshu Molybdenum in Huadian, Jilin Province
详细信息   
摘要


     Huadian Shuangyangshu molybdenum mineralization associated with intermediate-acid magmatic rock bodies of Indosinian to Yanshanian.Magmatic rock of Yanshanian intruded several times,it provided space and ore fluid source for mineralization.Fault zone,emplacement contact zone provided space location for the deposit.Ore bodies occurred in the porphyry and granodiorite veins,regional basement fault in NNW irection was ore–bringing structure,and NNE direction fracture formed in the later as the host structure;magma intrusion with tectonic process was precondition for formation of Shuangyangshu molybdenum deposit.Structures of NNE direction controlled deposit are more common in the central area of Jilin Province.
