摘　　要：吉林南部老岭群中产出的金矿分为三种类型,其中以荒沟山和南岔金矿为代表的微细浸染型和金硫化物浸染型最具规模。地球化学研究表明,该类矿床是与岩浆热液活动有关的中高温热液矿床。主要控矿因素是韧性剪切带和闪长岩脉的侵入,以及成矿热液的温度和容矿空间。The gold deposits of the Laoling Group, southern Jilin province are divided into three types, among them, the Huanggoushan and Nancha gold deposits with the fine impregnation type have quite large sizes. By the study on geochemistry shows that this kind of deposit is a meso—hypothermal deposit related to the magmatic hydrothermalactivities; main ore—control factors are ductile shear zone and the intrusion of the diorite vein, the hydrothermal temperature and host space.
