去年,在矿床模式化、贵金属勘查、水文地球化学、气体地球化学、数据处理和解释以及岩性地球化学方面都取得了显著的进展和成就。 地球化学在发展各类矿床的成因/工作模式方面起着不可缺少的作用。而那些关系又可用来修正地球化学勘查方法。斑岩型钼矿系统(Economic Geology,1981)、密西西比流域型矿床和贵金属矿床的修正模式及其勘查意义,都是去年值得一提的成果。 这一年贵金属勘查十分活跃。金的高度化学稳定性、低的天然丰度以及不均匀分布,给野外采样和室内分析都带来了困难。这年四月在温哥华举行了《科
Last year, significant progress and achievements have been made in the area of deposit modeling, precious metal exploration, hydrogeochemistry, gas geochemistry, data processing and interpretation, and lithology geochemistry. Geochemistry plays an indispensable role in developing the causes / modes of work for all types of deposits. And those relations can be used to revise the geochemical exploration method. The porphyry molybdenum system (Economic Geology, 1981), the correctional model of the Mississippi Valley deposits and precious metal deposits, and their implications for exploration are all noteworthy achievements of last year. This year, precious metals exploration is very active. The high chemical stability of gold, its low natural abundance and its uneven distribution have caused difficulties in both field sampling and in-house analysis. In April this year, held in Vancouver "Section
