吉林省杜荒岭金矿床地质特征及成矿规律浅析

杜荒岭金矿床赋存于燕山晚期的石英闪长(斑)岩中。矿体严格受NEE向断裂构造破碎带和隐爆角砾岩筒控制。从矿体形态、产状、规模及品位，矿石类型、组成及组构，矿化期次、矿化阶段的划分，围岩蚀变，金的富集规律等方面论述了矿床的地质特征，并对矿床成因进行了初步探讨，认为其属燕山晚期与次火山岩有关的中低温热液蚀变岩型金矿床。在总结本区找矿标志的基础上，指出了深部及外围找矿方向。

Geological Features and Prospecting Direction of Duhuangling Gold Deposit, Jilin

Duhuangling gold deposit occurred within the quartz diorite of Late Yanshan Epoch. The ore-bodies are directly controlled by NEE-trending fault structure zone and the eryptoexplosion beceia pipes. According to the morphotype, occurrence, size and grade of the orebody, ore types, mineral association and fabric, division of the mineralization periods and stages, wall rock alteration, enriched law of gold, the geological features of eaepiabu gold deposit are illustrated and the genesis of the deposit is preliminary discussed. This is a meso-epithermal alteration type gold deposit which related with subvoleanie rock of Late Yanshan Epoch. Based on the prospecting criteria in the area, the exploration direction in the deep and peripheral deposit is pointed out.
