五台山区,从19世紀初期起,先后有不少中外学者进行过地質調查,但所著論文,仅对前震旦紀变質岩系做了很宝貴的論述,而对該区矿产分佈的調查,似乎提到的較少。特別是对于五台东冶鎮附近所产之矽石矿,往往易被人所忽視。五台县所产之矽石矿,在敌伪时期虽曾进行过調查开采,但因系掠夺性質,故仅对矽石矿之埋藏儲量做了粗略估計。直至解放后,随着国家工业建設的发展需要,才在此区进行了詳細的地質勘探工作。1954年底原华北地質分局刘長龄同志对五台矽石进行显微鏡研究,并提出“这种矽質岩是由于原先沉积之燧石
Since the beginning of the 19th century, many Chinese and foreign scholars have carried out geological surveys. However, the dissertation only makes a valuable exposition of the Pre-Sinian metamorphic rocks, and the survey on the mineral distribution in this area Seems to mention less. Especially for the production of silica near the town of Wutai East, often easily overlooked. Silica mines produced in Wutai County have been surveyed and exploited during the period of the enemy and puppet. However, due to the predatory nature, only a rough estimate of the burial reserves of the silicic mines has been made. Until the liberation, with the development of national industrial construction needs, only in this area conducted a detailed geological exploration work. At the end of 1954, Comrade Liu Changling, formerly from North China Bureau of Geology, conducted a microscopic study of Wutai Silica and proposed that "this kind of chert is due to the original chert
