摘要
甘肃白龙江某金汞矿带的7个化探次生晕异常经灰色关联分析,得出其找矿优势排序为:2号—3号—1号—4号—5号—6号—7号。广西贵县某金银锑多金属矿区的灰色系统建模预测表明:寒武系有利于Au,Ag,As,Pb富集;泥盆系则有利于Zn。
Through grey correlation analysis on seven geochemical secondary haloanomalies in a certain Au-Hg mineral best of Bailong river, Gansu, correlationpredominant ordering of their exploration is No.2-No.3-No.1-No.4-No.5-No.6-No.7. Grey system modelling prediction of a certain Au-Ag-Sbpolymetallic mining area in Guixian county, Guangxi shows that mineralization-concentration layers of Cambrian system are favourable for Au, Ag, As andPb, and ones of Devonian system are favourable for Zn and Sb.
