河北陈小铺金矿矿床特征及找矿标志

Hebei Chenxiaopu characteristics and prospecting criteria of gold deposits

陈小铺金矿位于内蒙古高原的东南缘兰城子-闫巨沟-蔡家营铅锌金银多金属成矿带,在本区古元古代裂谷活动中,发生了海底火山的喷发和沉积作用,除喷出大量的基性岩浆外,形成了红旗营子群火山-沉积岩地层,还有大量成矿物质的堆积。随后,又受到中生代构造岩浆热事件的叠加,使矿体再次经受了活化改造,有可能又有新的成矿物质加入,使矿体最后定位。区内共圈定金矿体2个。本文阐述了成矿地质背景、矿床地质特征、矿体特征、矿石质量特征,探讨了矿床成因类型,总结了区内找矿标志。

The Chen Xiaopu gold deposit is located in the southeast edge of the Inner Mongolia plateau LAN Cheng Zi-Yan Ju Gou-Caijiaying Pb Zn Au polymetallic metallogenic belt in the area of Paleoproterozoic rift activity, occurred eruption and sedimentation of submarine volcano, the basaltic magma spewed, forming a red flag camp volcano sedimentary subgroup rock, there are a large number of mineral deposits. Subsequently, it was superimposed by the Mesozoic tectonic magmatic thermal events, which made the ore bodies undergo the activation and reconstruction again. It is possible that new ore forming materials will be added to make the ore bodies finally locate. There are 2 ore deposits in the area. This paper expounds the metallogenic geological background, the geological features of the deposit, the characteristics of the ore bodies and the quality characteristics of the ore, and probes into the genetic types of the deposits, and summarizes the prospecting marks in the area.
