河南桐柏地区石墨矿地质特征与找矿方向
Geological Characteristics and Prospecting Direction of Graphite Deposits in Tongbai Area,Henan Province
摘要
Abstract
The research area has good prospects for graphite ore exploration,with 1 large graphite deposit,2 medium-sized deposits,and 1 small deposit delineated.The graphite ore body mainly occurs in the contact area between quartz schist(or gneiss type)and marble in the Yanlinggou formation of the Paleoproterozoic Qinling rock group.The genetic type is regional sedimentary metamorphic type,and the ore type is mainly quartz schist(or gneiss type),supplemented by marble type.The thickness of the graphite ore body varies steadily,and its strike is consistent with the main structural line of the region,with a banded distribution.Comprehensive research shows that the graphite ore body and the host strata are produced in a complex anticline pattern under the later tectonic compression,and the distribution area of the Yanlinggou formation is an important direction for future exploration.Adopting appropriate geophysical methods can help to quickly locate the prospecting target area.In mineral exploration,boreholes should be arranged at favorable fold structures based on the anticlinal fold morphology of the graphite ore body,which can achieve twice the result with half the effort.关键词
