| 摘 要： | 我国西北部一些戈壁荒漠区经历长期的风化侵蚀作用而形成准平原,景观演化过程改变了元素的分散模式,对地球化学勘查是很大的难题.为了研究戈壁覆盖区元素在准平原化过程中的分散与迁移情况,选择新疆金窝子金矿,并运用空气动力反循环钻开展了采样研究工作.结果表明:金倾向于在矿体上方垂向剖面的顶层和底层土壤中富集;地表或近地表富粘土层... |

| Abstract: | Some Gobi desert terrains in northwestern China are peneplains formed by a long period of erosion.Dispersion pattern of elements is changed under this kind of landscape evolution.Jinwozi gold deposit was selected for study of element dispersion and migration in the process of pediplanation by using overburden drilling sampling.The results show that(1) gold tends to concentrate in the top and bottom of the vertical profile over the ore body;(2) gold is enriched in the fine-grained fractions of soils with cla... |
