| 中文摘要: |
| 文章通过冲积平原区(山东王家庄铜矿区)的地气试验研究及其与常规土壤测量结果的对比,总结了冲积平原区隐伏金属矿矿床上方地气元素的分布特征。研究结果认为:①在不同覆盖条件、常规土壤测量无效的情况下,地气测量均可发现清晰的金属元素异常,异常强度高,且与矿体空间位置相吻合;显示出地气法在厚覆盖条件下对隐伏金属矿的独特作用;②液体捕集剂和ICP-MS分析方法提高了地气法捕集效率和分析测试数据的可靠性,为地气法的标准化和工程化提供了技术支持,为隐伏金属矿的勘查提供了有效地球化学手段。 |
| 英文摘要: |
| Distribution characteristics of geogas elements over metallic deposits concealed by alluvial plain are sumarized on basis of geogas test and research on Wangjiazhuang Cu deposit in Shandong province and comparison between the geogas survey and conventional soil geochemical survey.The results show that: ① the geogas survey displays clear metal element anomalies that are not displayed by conventional soil gochemical survey under various cover conditions and the geogas anomaly is strong and well coincided spatially with the ore bodies thus geogas survey is unique to discover concealed metallic deposit;② the liquid trapping agent and ICP-MS technique improves trapping efficiency and reliability of geogas data and provides technical support of standarization and engineering apllication for the geogas technique and the geogas technique provides a geochemical tool for concealed metallic deposits. |
