人类发现和利用金,已有很久的历史,我国又是找金、采金和应用金的古老国家之一.从我国的地质条件看,完全可能找到更多的金来为四化服务.因此,加强对金矿的研究,尤其是对金在自然界中的性状-分布、分配、迁移、富集规律的研究,是十分必要的.本文试图对金的若干地球化学问题作一综述和讨论,供同志们参考. 金在地壳中的分布量Au的原子序数为79,自然界只有其唯一的同位素Au~(197).奇数原子序数,奇偶型的原子核,49+1型的核,原子序数很大,平均结合能很小.这些特点决定了金在自然界中的分布量很少.又
It has been a long time since mankind discovered and used gold, and our country is one of the ancient countries that sought gold, gold mining and gold application. From the geological conditions in our country, it is entirely possible to find more gold to serve the four modernizations. , It is very necessary to strengthen the study of gold deposits, especially the research on the characters, distribution, distribution, migration and enrichment of gold in nature.This paper attempts to review and discuss some of the gold geochemical problems, For Comrades reference Gold Distribution in the Earth’s crust The atomic number of Au is 79, only its only isotope Au ~ (197) in nature. Odd, odd and even nuclei, 49 + 1 type of nuclear atomic number is very Large, average binding energy is very small. These characteristics determine the distribution of gold in nature is very small.
