地球化学勘查，主要是利用先进的微量元素测定技术，系统地研究各种天然物质（如岩石、疏松沉积物、水系沉积物、水、气体、生物等）中元素的分布和分配特征，从而获得找矿信息的一种找矿方法。在我国，从五十年代初期至今三十多年来，化探工作从无到有，化探队伍由小到大，建立了一支有一定基础的专业队伍，初步形成了我国自己的方法技术体系，获得了丰硕的地质—找矿成果。 Geochemical exploration, mainly the use of advanced trace element determination techniques, systematic study of the distribution and distribution of elements in a variety of natural substances (such as rocks, unconsolidated sediments, sediments, water, gases, organisms, etc.) to obtain A prospecting method for prospecting information. In our country, from the early 1950s up to the present more than 30 years ago, geochemical exploration work has grown from nothing to as large as the number of geochemical exploration teams, establishing a contingent of professionals with a certain foundation and initially forming our own method and technology System, access to a rich geological - prospecting results.
