吉林省的金属矿产和煤炭资源,主要分布在东部山区。其中玄武岩覆盖区的面积为26000km~2。一九八一年以来,在玄武岩覆盖区找到煤,这个可喜的信息,为我们地质工作者揭开玄武岩覆盖区的秘密指明了广阔的前景。长期以来,在大面积玄武岩盖层下找矿工作一直没有重大突破,因此我局将该项工作列为地质工作三大攻关课题之一。其目的是应用物探方法,确定玄武岩厚度,揭去盖层,了解下伏地层和地质构造,填出基岩地质图,打开找矿局面。
Jilin Province’s metal mines and coal resources are mainly distributed in the eastern mountainous areas. The basalt area covers an area of 26000km ~ 2. The welcome message of finding coal in the basalt area since 1981 is a clear indication of the secrecy of the geological coverage of our basins by our geologists. For a long time, there has been no major breakthrough in the prospecting work for large-area basaltic cover. Therefore, the Bureau has listed this work as one of the three key topics of geological work. Its purpose is to use geophysical methods to determine basaltic thickness, remove cap rocks, understand underlying formations and geological formations, fill in bedrock geologic maps, and open prospecting scenarios.
