Title: Analysis of Geological Characteristics and Mineralization of Gold Deposits in Eastern Jilin
Abstract: It has been discovered that there are about 39 gold ore deposits at the east of Jilin province(Yanbian area),including several type of deposits,such as big-type deposits,middle-type deposits and small-type deposits.This area is the classic area of volcanic hydrothermal type gold deposit of mesozoic.According to the analysis of geological characteristics and ore-forming in this ore-field,we find that the ore deposit of this area is related with mesozoic volcanic rocks and sub-volcanic rocks.The ore containing wall-rock includes the late jurassic-early cretaceous volcanic rocks,which have been deep altered,and diorite porphyrite,quartz diorite porphyrite(or granitic porphyry),which are controlled by regional structures.Most of the ore-forming material in this gold deposit is from upper-mantle,the ore-forming solution is the mixed fluid of magmatic hydrothermal and atmospheric precipitationr.
