摘要
穿透性地球化学勘查技术通过获取覆盖层不同介质中的穿透性信息,以此达到指示隐伏矿体的目的。系统总结了活动态金属离子测量、酶提取测量、金属元素活动态测量、地电化学技术、植物地球化学技术、地气测量等几种穿透性地球化学勘查方法的理论基础和实际应用效果。指出今后应该加强元素迁移机理、元素卸载机制及元素卸载后在地表表现出的异常模式等异常形成机理研究,并进一步总结和研究穿透性地球化学勘查技术的矿种和景观适用性问题,从经济适用性角度出发,各种勘查技术要向着简化采样、分析流程和提高方法技术的稳定性努力,以便更加高效经济地开展覆盖区找矿工作。
It is a worldwide challenge to explore the deeply buried deposits. Deep-penetrating geochemical exploration methods were developed to solve the problems of how to get the information of the buried deposits in the covered layer. The methods were successfully used to indicate some buried deposits, but not all kinds of deposits. What is more, a method cannot be used in all kinds of landscapes. In this paper, theories and case studies of deep-penetrating geochemical exploration methods, including mobile metal ions, enzyme leach, leaching of mobile forms of metals in overburden, electro-geochemical extraction method, biogeochemical exploration, nano-metal in geogas were reviewed. Elements migration, unloading mechanism and anomaly models are the most important parts for deep-penetrating geochemistry and need to be further investigated. From the perspective of economic efficiency and applicability, sampling and analyzing procedures should be simplified to improve the stability of all methods.
