摘要:
在20世纪的找矿实践中,水系沉积物、土壤和岩石地球化学测量等传统化探方法发挥了令矿产资源勘查界瞩目的重要作用。随着深部找矿，特别是覆盖区找矿工作的日益增多，传统化探方法已不完全适应这种找矿条件，急需有新的方法技术予以补充。20世纪诞生的一套非传统化探方法，如选择性提取法、生物地球化学测量、地下水地球化学测量、地下气体测量等，重又受到青睐。在现代化学分析技术的支撑下，选择性提取技术成为当前化探界研究的热点，试点性研究显示了其找寻隐伏矿的有效性；生物地球化学找矿方法在植物积累元素的控制条件、分析测试方面均取得了较大进展，已经从幼年期进入成熟的早期阶段；地下水地球化学测量方法在地下水中矿物饱和度与物质计算、高质量的物理化学数据的获取和不同矿床类型的元素化合物指示标志的研究与评价方面做了大量的工作。同时，数据处理技术、重矿物地球化学找矿标志和同位素地球化学示踪技术的研究近年来也受到了极大关注。实验性研究表明，尽管这些非传统技术在找寻隐伏矿方面显示了良好的应用前景，但仍有许多问题需要深入研究。
Abstract:
Nowadays, there are more and more need of deep ore-prospecting especially in those covered areas, however, traditional geochemical prospecting methods are not enough under these conditions. Therefore, new supplementary technical approaches are badly needed. A series of non-traditional geochemical prospecting methods such as selective extraction, biogeochemical survey, groundwater geochemical survey and underground gas survey have recovered to be favorable again. Supported by modern analytical technology, selective extraction is now becoming the focus of the frontier, and its efficiency in hidden ore-prospecting has been proved by trial research. For biogeochemical technology, much achievement has been made in terms of controlling condition and analysis test of element enriched in plants, which indicates a transforming from infant stage to more mature early stage. Besides, much work has been done using groundwater geochemical survey technology in mineral saturation and substance calculation, and in high-quality physical and chemical data acquired and mineral compound indicator of different deposit types. Meanwhile, data processing technology, heavy mineral geochemistry prospecting indicator and isotope geochemical tracing technology has also attracted much attention in recent years. Still, according to experimental test, although the application of these non-traditional geochemical prospecting methods is promising, there is a lot of further work to do.
