摘要
通过河南桐柏马道地区1∶5万水系沉积物测量和元素地球化学特征分析研究认为,Au、Ag、Cu、Pb、Zn、Cr、Ni、Fe 8种元素为区内主要成矿元素,共圈出单元素异常831个、综合异常27个,地球化学异常严格受地层、大河断裂带及其次级断裂、岩浆岩等因素联合控制。结合综合异常特征以及成矿地质条件,圈定了围山城金银多金属矿找矿远景区、刘山岩铜锌多金属矿找矿远景区、月儿湾金银多金属矿找矿远景区、老和尚帽银多金属矿找矿远景区4处。通过对远景区综合异常查证,在围山城5-甲_(1-1)和11-甲_(1-1)、刘山岩14-甲_(3-1)、月儿湾2-甲_(3-1)、老和尚帽24-甲_(2-2)综合异常区发现与异常相关的矿化信息,为下一步地质找矿工作指明了方向。
Based on the 1∶50000 stream sediment survey and element geochemical characteristics analysis of Maodao area in Tongbai,Henan Province,the paper believes that Au,Ag,Cu,Pb,Zn,Cr,Ni and Fe are the main metallogenic elements in the area.It delineated 831 single element anomalies and 27 comprehensive anomalies.The geochemical anomalies are strictly controlled by strata,Dahe fault zone and its secondary faults,magmatic rocks,and other factors.Combined with the comprehensive anomaly characteristics and metallogenic geological conditions,four prospecting areas of Weishancheng gold silver polymetallic deposit,Liushanyan copper zinc polymetallic deposit,Yueerwan gold silver polymetallic deposit and Laoheshangmao silver polymetallic deposit were delineated.Through the comprehensive anomaly verification of the prospecting areas,the mineralization information related to anomaly was found in Weishancheng 5-A_(1-1),11-A_(1-1),Liushanyan 14-A_(3-1) and Yueerwan 2-A_(3-1),and Laoheshangmao 24-A_(2-2) comprehensive anomaly areas,which indicates the direction for the next geological prospecting work.
