Geochemistry is the bridge between geology and chemistryThis is why geochemistry is the bridge between chemistry and geology. The study of the properties and reserves of the world's mineral materials, geochemistry, combined with crystallography, not only reveals the structure of crystals but also sets the course for industrial development. Thus, from geology to geochemistry, from geochemistry to physics and chemistry, these disciplines are linked in a chain. The ultimate purpose of these sciences is not only to develop natural science, but also to improve people's living standards.So how to create new valuable materials and control the raw materials needed by the national economy -- that is the biggest and most important stimulus today. Geochemistry and technology are closely combined to study the properties of salts and ores, clarify the distribution of rare elements in ores and salts, and find out the best way to use underground "enrichment".
