Main Minerogenetic Epoch, Determine and Exploratory Direction of Jiapigou Gold Deposit, Jilin
吉林夹皮沟金矿床主成矿时代的确定及找矿方向

Main minerogenetic epoch in Jiapigou gold deposit had not been determined before,which results in ore area and field exploratory to have been in wavering stage, and is now determined by the authors as Yanshan Epoch by synthesizing geological analysis of tectonics, magmatic rocks, vein rocks and typomorphic minerals, combining K_Ar statistics in 44 vein rock, determining Rb_Sr isotopic epoch in quartz aerohydrons, gold_quartz vein. Yanshan Epoch is the best epoch of subduction of Pacific plate to Eurasian continental crust, leading to intense magmatic activity in the East of North China platform and formation of deep fault and circum_Pacific minerogenetic belt. Metallogenic prognosis province should be mainly selected in the Mesozoic tectonic systems and nearby vein rocks by both sides of Jiapigou_Dalazi deep fault.
