一、緒言 箇旧錫矿是一个具有悠久的开采历史的矿区,据汉書記載,汉代已知有錫。据文史舘考据,箇旧各矿田之开采当早于1465年(明成化元年)。解放以前曾有多数地質人員进行地質調查工作,由于当时缺乏計划性和目的性,調查方法亦无系统,質量又低劣,更无所謂地質勘探,故所获成績显然不多。 I. Introduction 箇 old tin mine is a mine with a long history of mining, according to Han records, known to the Han Dynasty tin. According to the examination of the Museum of Literature and History, the mining of the old mining fields was as early as 1465 (the first year of Ming Chenghua). Before the liberation, most of the geologists carried out geological investigations. Due to the lack of planning and purpose at that time and the lack of systematic, poor quality and even more geophysical investigations, there were obviously not many achievements.
