在辽东成矿带找寻层控型金矿床靶区

Looking for Strata Bound Type Gold Deposit in Liaodong Metallogenic Belt

辽东成矿带是武警黄金第四支队重点勘查的区带之一,已发现小佟家堡子、猫岭等层控型大型金矿床。在塔子岭—青城子14号1∶5万哑铃状金异常区(大异常)的右半部已发现小佟家堡子超大型金矿床,高家堡子大型银矿床、白云、青城子金矿床、青城子大型铅—锌矿床;左半部异常区成矿条件与右半部基本类似,目前仅发现一些金矿(化)点,尚无成形金矿床,因此左半部成为首选调查区。通过与有大型金矿床的9号异常相对比,确定As-2,As-3,As-4,As-5,As-8号异常是今后地质勘查的主要工作对象。确定了集安七宝沟—恒仁仙人洞、凤城三家子—青城子、盖县猫岭—新甸3处金找矿靶区。

Liaodong metallogenic belt is one of the important prospecting areas of No.4 Gold Geological Party of CAPF,where have been found stratabound gold deposits,like Xiaotongjiapuzi,Maoling and so on,and which shows a fine prospecting potential in this area.Xiaotongjiapuzi super large-scale gold deposit,Gaojiapuzi large scale silver deposit,Baiyun gold deposit,Qingchengzi gold deposit and Qingchengzi large-scale Pb-Zn gold deposit have been found in the right part of No.14 1∶50 000 dumbbell-shaped gold anomaly area in Taziling-Qingchengzi.Left part of anomaly area has similar metallogenic conditions as right part,and several gold mineralized points have been found in the area.So left part become prior choice of prospecting.Compared with No.9 anomaly area of large scale gold deposit,make anomaly As-2,As-3,As-4,As-5,As-8 as the main objects in the future geological prospecting.We fixed three gold prospecting targets,there are Ji’anqibaogou-Hengrenxianrendong,Fengchengsanjiazi-Qingchengzi and Gaixianmaoling-Xindian.
