古马岭—大红胡子金矿区地质特征及资源潜力分析

Analysis on geological characteristic and resource potential of Gumaling-Dahonghuzi gold deposit

古马岭—大红胡子金矿床是近几年在吉林省南部新发现的大型低品位蚀变岩型金矿床,已提交金资源/储量近20 t。矿床以受层位控制、易采易选、品位低、规模大为其特点。重点阐述了矿区的地质特征,总结了成矿规律,并对该区的资源潜力进行了分析,结果认为,古马岭—大红胡子金矿床有望达到大型—超大型矿床的规模。

Gumaling-Dahonghuzi gold deposit is a large low-grade altered rock gold deposit newly recovered in south Jilin.The gold resources（or reserves） submitted is nearly 20 t.The deposit is controlled by horizontal layers,and is easy to stope and process.The ore grade is low and the deposit scale is large.The geological characteristics of the ore district are introduced and the metallogenic regularities are concluded.The paper analyzes the resource potential of the district,as well.It is believed that the deposit may be a large to super large one.
