摘要
为实现栖霞地区金矿找矿突破,在毕郭地区开展1∶50 000水系沉积物测量的基础上,进行Au、Ag等为主的16种元素分析。对元素分布特征、富集离散特征及异常特征进行研究,并进行各元素的R形聚类分析和因子分析。结果表明,研究区内以Au为主的成矿各元素异常强度高,规模大,套合性好的异常,主要分布在与区内主成矿及其次级断裂带。结合区内地质、物探及矿产特征,圈定5处金找矿预测区:笏山金矿的深部及外围A级预测区1处、台前金矿深部B级预测区1处、孙疃-大河崖、三宿夼和大花园地区C级预测区各1处。
In order to achieve a breakthrough in gold prospecting in Qixia area,16 elements mainly including Au and Ag which were on the basic of the stream sediment survey in 1∶50000 scale of the Biguo area was analyzed.The distribution characteristics,enrichment and dispersion characteristics and abnormal characteristics of elements were studied,and the R-type clustering analysis and factor analysis of each element were carried out.The results show that the anomalies of Au dominated metallogenic elements in the study area are of high intensity,large scale and good coincidence,which are mainly distributed in the main metallogenic and secondary fault zones in the area.In combination with the geological,geophysical and mineral characteristics in the area,five gold prospecting prediction areas are delineated.There is one deep and peripheral A-level prediction area of Hushan gold mine,One deep B-level prediction area of Taiqian gold mine,and three C-level prediction area in Suntuan daheya,sansukuang and Dahuayuan area.
