一、概述我国是世界上最早使用黄金的国家之一。早在秦汉时代，陕西等地就有采掘黄金的记载，到清代光绪年间，我国产金量已达43.2万两，为世界黄金产量的7％，居世界第五位。建国以后国家对黄金生产愈来愈重视，金矿资源的勘查也日益提到重要位置上来。我国黄金地质工作大体分为四个阶段：第一阶段，1949～1957年，是金矿地质起步时期，只做了一些初步勘查工作，探明储量很少；第二阶段1958—1975年，是发展前进和倒退交织的时期，1962年探矿队伍在胶东半岛上钻、1964年十多台钻机在小秦岭勘查金矿，短短几年取得了很大成效，发现了胶东花岗岩内破碎带蚀变岩型岩金矿、小秦岭石英脉型岩金矿。找矿工
I. Overview China is one of the earliest countries in the world to use gold. As early as the Qin and Han Dynasties, Shaanxi and other places had records of gold mining. By the Qing dynasty, the gold production in our country reached 432,000 taels, accounting for 7% of the world’s gold production and ranking the fifth in the world. Since the founding of the People’s Republic of China, more and more attention has been paid to gold production. Exploration of gold resources has also increasingly mentioned the important position. The gold geological work in our country can be roughly divided into four stages: The first stage, from 1949 to 1957, is the gold geological start-up period, only some preliminary exploration work was done, and the reserves proved to be few. During the second stage from 1958 to 1975, During the period of development and retrogression, the exploration team drilled in Jiaodong Peninsula in 1962. In 1964, more than 10 drilling rigs explored gold mines in the small Qinling Mountains. In just a few years, great achievements have been made and the alteration of the crushing zone in the Jiaodong granite was discovered Rock type gold deposit, small Qinling quartz vein type gold deposit.
