浅覆盖区矿产勘查中原生晕轴向分带序列研究及深部预测
|
摘要
我国在基岩出露区的矿产勘查程度较高,而在大面积的浅覆盖区因基岩出露较少,覆盖层以下的基岩和构造分布不容易查明,尤其是贵金属矿、有色金属矿等较其他矿种规模小,物、化探勘查方法使用范围有限,所以未形成有效的矿产勘查方法。文章通过对下黑山金矿点3号主矿脉钻孔的岩石化探样品进行多元统计分析和原生晕轴向分带序列的研究,得出3号主矿脉的原生晕分带序列为Zn-Hg-Sn-Sb-Cu-BiAu-As-Mo-W-Ag-Pb。分带序列出现头尾晕的叠加,即"反分带"的特征,推测深部存在盲矿体的可能性比较大。
In China,most of mineral exploration has been done in the bedrock exposed areas,and a little has been done in the large shallow covered areas due to less exposed bedrocks over there.It is not easy to identify the bedrock and tectonic distribution in the overburden areas,specially in where precious and nonferrous metal deposits exist.Generally the precious and nonferrous metals deposits are much smaller than other mineral resources. Given the limitation of using geophysical and geochemical exploration method in these shallow covered areas,there are no effective mineral exploration methods has been proven. In this paper,we take Heishanjin No. 3 gold point as example and have do some study on the primary halo-zonal sequence to provide a way of conducting mineral exploration in the shallow covered area. Xiaheishan gold mine point is located in the southeastern part of Inner Mongolia Ongniud Bannar,the regional geomorphology is a shallow coverage area,the rock outcrop is less,the structure is not obvious,combined with the geochemical exploration work of this area is relatively small,bring great difficulties to mineral survey; The study of the primary halo zonation sequence of the gold ore body will help to guide the deep prospecting and predict the mineralization prospect. Based on the multivariate statistical analysis and the calculation of the primary halo zonal sequence,it has been found that the primary halo-zonal sequence of the main vein of No.3 gold point is Zn-Hg-Sn-Sb-Cu-Bi-Au-As-Mo-W-Ag-Pb,and there is superposition happened for the head and tail of halo-zonal sequence called as "reverse zoning",and accorringly which it is predicted that there probably exsits a large blind ore deposit in the depth.
