| 摘 要： | 内蒙古中东部半干旱荒漠草原景观区选择B层-5～+40目粗粒级段的风化岩屑样品可以有效地排除风成沙的干扰,突出成矿及指示元素的地球化学异常特征.文中介绍了该景观条件下开展岩屑地球化学测量的方法技术,分析了白音查干矿区、油房西矿区和小东沟矿区的化探异常特征和找矿成果.认为在半干旱荒漠草原景观区开展岩屑地球化学测量是行之有效的找矿方法,已取得了明显的化探异常圈定和地质找矿效果. |
| 关 键 词： | 半干旱荒漠草原景观区 岩屑地球化学测量 找矿效果 内蒙古中东部 |

| Abstract: | In the semi-arid desert and grassland area,geochemical debris survey sampling tests show that grain size(-5 ~ +40 mesh)of sampling medium clastic materials from B layer of soil can effectively remove the interference of aeolian sand and show high geochemical anomalous values.Based on the analysis of geochemical anomalous features and its exploration effects in the Baiyinchagan,Youfangxi and Xiaodonggou ore fields,it is demonstrated that geochemical debris exploration method is effective,and has outlined som... |
