| 摘 要： | 本文选择被风化物覆盖(4米至几十米厚)的金窝子金矿作为研究对象。分析矿体上方风化层和非矿上方的垂直剖面中的各种金属元素的总量及活动态含量,以获得金属元素在风化层中的活动规律,为化探找矿提供方法依据。结果发现金等的某种活动态的分布模式在矿体上方呈现双层分布,即他们趋向于在垂直剖面的底部与顶部富集,而在中部降低。可以解释为元素在剖面底部风化层中的富集是由于金继承了矿体的风化产物,而在地表或近地表的富集是由于从矿体迁移至地表的元素被粘土物质和铁锰氧化物膜所吸附。 |

| Abstract: | Desert terrains in the northwestern China are widely covered by regolith sediments,which mask geochemical signals of ore bodies and are a main obstacle to mineral exploration.It is needed imminently to study the vertical geochemical variation of metal elements and the potential transfer mechanism from the ore body to its regolith cover and to the ground surface in order to find proper samples in the field and to choose proper analytical methods in the laboratory.The Jinwozi gold deposit which is covered by ... |
