华北陆块晋冀成矿带十八盘金矿地质特征与找矿标志研究

Research on geological characteristics and prospecting marks of Shibapan Gold Deposit in Shanxi-Hebei Metallogenic Belt of North China Block

河北省迁西十八盘金矿位于华北陆块晋冀成矿带上,该带为我国重要的金属资源基地之一,带内矿床类型多样、复杂,以铁、金、铅、锌、金、银等矿产资源为主。矿床成因多样,明显受地层、构造、岩浆岩等多系统控制、具多期成矿特点。以十八盘金矿为研究对象,在大比例尺专项地质测量、老硐清理编录的基础上,采用槽探、坑探、钻探等山地工程和分析测试等技术手段和综合研究,查明了区内金矿脉分布情况,矿体特征、金的赋存状态等,表明综合地质调查方法在区内能够取得较好的找矿效果,丰富了成矿带内找矿成果,提出区内具有寻找斑岩型—低温热液型矿床系统条件,可为研究区进一步工作提供参考。

The Shibapan gold deposit in Qianxi,Hebei Province is located in the Shanxi Hebei metallogenic belt of the North China landmass.This belt is one of the important metal resource bases in China.The types of deposits in the belt are diverse and complex,mainly including iron,gold,lead,zinc,gold,silver and other mineral resources.The genesis of the deposit is diverse,obviously controlled by strata,structures,magmatic rocks and other systems,and has the characteristics of multistage mineralization.Taking Shibapan Gold Mine as the research object,on the basis of large-scale special geological survey,old cave cleaning and cataloging,using trenching,pit exploration,drilling and other mountain projects,analysis and testing and other technical means and comprehensive research,the distribution of gold veins,ore body characteristics,gold occurrence state,etc in the area had been found out,indicating that the comprehensive geological survey method could achieve good ore prospecting results in the area,and enrich the ore prospecting results in the metallogenic belt.It was suggested that there were systematic conditions for searching porphyry-low-temperature hydrothermal deposits in the area,which could provide reference for further work in the study area.
