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

Zhang Wenbo (Jilin Geological Prospecting Bureau of Non Ferrous Metals)  
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.
