吉林省大黑山条垒北东段金、银成矿系列的划分

The division of mineralized series of gold,silver in the northeastern section of Da Hei Shan Striped Rampart

大黑山条垒北东段划分为三个金、银矿化集中区，各集中区内成矿地质条件各有特色，矿床成因类型大致可分三种：北部机房沟区以变质热液型为主；南部放牛沟区以火山沉积－热液叠加改造型为主；中部兰家—八台岭区以矽卡岩－岩浆热液型为主。从而，相应地建立起三个成矿系列，为矿产预测提供理论依据。

The northeastern section of Da Hei Shan Striped Rampart is divided into three mineralized concentration areas of gold and silver.The geological conditions of each concentration area has its own characteristics.There are roughly three genetic types of ore deposit,namely ① mainly metamorphic hydrothermal type which concentrates in Ji Fang Gou District in the north part ② mainly reformation type of volcanic sedimentation hydrothermal overprint which concentrates in Fang Niu Gou District in the south part ③mainly skarn magmatic hydrothermal type which concentrates in Lanjia Batailing District in the central part,thus the three mineralized series are established which provide theoretical basis for prognosis of ore prospecting.
