地球化学方法在福安堡钨钼矿床的应用

吉林省中部大面积森林覆盖区,分布着大面积华力西期、印支期花岗岩类,受传统成矿理论的束缚,这一地区成为有色金属矿产勘查的"处女地"。1:20万化探扫面之后,相继开展了不同方法的地球化学异常查证工作,发现了很有前景的福安堡钨钼矿床。结果表明,在东北森林覆盖区化探找矿方法十分有效。

THE APPLICATION OF GEOCHEMICAL EXPLORATION METHOD TO THE FUANBU W-Mo DEPOSIT

The Variscan-Indosinian granites are distributed in a large area covered with forests in central Jinlin Province.Fettered by traditional geological theory, geologists have regarded the area as "virgin land" in search for nonferrous metals.However, the new generation of geochemical reconnaissance at a scale of 1:200 000 led to the discovery of the Fuanbu W-Mo deposit, which is of great potential. The results of the geochemical reconnaissance show that the method used is effective in ore prospecting and also has such merits as reduction of vegetation damage in mineral exploration and protection of environment.
