| 中文摘要: |
| 鲁西铜石地区是上世纪末期新发现的金矿聚集区。文章在已有找矿模型的基础上,对预测模型的三大类找矿信息进行量化及运算;采用了不同权重求和方案,根据经验分别赋予地质信息、地球物理信息和地球化学信息的权重系数,使这三大类信息图层成为带权重累加的综合信息图层,并分别圈定一、二、三级预测找矿靶区,其中圈定一级靶区4个。对靶区进行的野外检查发现,一级预测区矿化蚀变较强,三级预测区相对较弱,并且在一级预测区发现金矿点一处。 |
| 英文摘要: |
| Tongshi area is a newly discovered Au-deposits-clustered area in western Shandong province in the last century. Based on the prospecting model three types of (geological, geophysical and geochemical) information for the prognosis model is quantified and calculated. Different weight sum scheme are adopted and empirical weight coefficient are given to the three information and the information are plotted into three layers integrated with accumulative evidence weight by which targets of class I, II and III are delineated. There are 4 class I targets. Field check shows that strong alteration-mineralization occur at class I target and weak at class III targets. An Au ore occurrence is discovered at a class I target. |
