1988年10月,苏联召开了“现代条件下地球化学找矿的理论与实践”会议. 会议肯定了地质勘探过程中各个阶段地球化学方法日益增长的作用.在1982～1988年期间,岩石化学、水化学、生物地球化学以及原子化学和地电化学找矿方法的科学原理得到进一步发展.建立了根据地球化学数据(P_3,P_2,P_1)评价预测资源 In October 1988, the Soviet Union convened a conference entitled “Theory and Practice of Geochemical Prospecting in Modern Conditions.” The conference affirmed the growing role of geochemical methods at various stages in the geological prospecting process. During 1982-1988, petrochemical, The scientific principles of water chemistry, biogeochemistry and atomic and electrochemical methods have been further developed, and a set of prediction resources based on geochemical data (P 3, P 2, P 1)
