| 中文摘要: |
| 内蒙古东部成矿地质条件有利,找矿前景巨大。由于风成砂土等的影响,地球化学勘查方法的使用受到限制,通常表现是异常弱,矿化指示作用不强。针对这一问题,选择金达莱钼矿为试验区,通过分析数据统计参数、地球化学异常特征等手段,开展了土壤测量样品加工粒级对比试验,目的是优选出更有效的分析测试物质组分和元素,起到强化异常的作用。结果表明,金达莱试验区-20～+60目土壤粒级组分较-120目粒级组分中元素含量变化程度大,元素异常更明显,有效的指示元素有Mo、Cu、Zn、Ag等。 |
| 英文摘要: |
| Despite the fact that the geologic condition of eastern Inner Mogolia is advantageous for the mineralization,geochemical exploration is disturbed by the aeolian sand so that the geochemistry anomaly is too weak to indicate mineralized zone. There is a focus on this challenge. To strengthen anomalies by means of choosing effectual indicators,comparative study of soil survey sampling grain size grade is done through analysing statistics parameters and the characteristics of anomalies in Jindalai molybdenum mine. Comparative study demonstrates the coarsegrained (-20～+60 mesh) is prior to the fine-grained (-120 mesh) in the field of exhibiting anomalies. And our studies provide some effectual referential elements such as Mo,Cu,Zn,Ag and so on. |
