近几年来,我們在地质測量与找矿工作上,已获得了一定的成績,直接找到了許多矿产地或有望地区,查清了若干矿点做出了评价,并在地質理論和技术水平上获得了很大的提高。但是不能否認,在我們过去的找矿工作中还存在着很多的缺点。特別是在一九五五年以前,我們的地质測量与普查找矿工作配合得不够密切,在工作中一方面是孤立的进行矿点檢查,忽視对区域地質及成矿条件的了解,另一方面虽然进行了正规地質測量,但忽視对每一矿化现象的檢查和研究,未能达到找矿的目的,或者是檢查工作做得不彻底,做出了片面的結論。为了克服这一缺点,东北分局普查队及各勘探队的小型普查队在近二、三年以来,在各矿区外圍以正规区域地質測量結合檢查找矿的方法,开展了普查找矿工作。实踐結果証明这
In recent years, we have obtained some achievements in geological surveying and prospecting work, directly found many mineral or prospective areas, identified a number of mine sites to make an assessment, and in the geological theory and technical level Got a lot of improvement. However, we can not deny that there are still many shortcomings in our prospecting work. In particular, before 1955, our geological survey and census prospecting work did not work closely enough. On the one hand, we carried out mine site inspections in isolation on the one hand, ignoring the understanding of regional geology and metallogenic conditions and the other Despite formal geological surveys, they ignored the inspection and study of each mineralization, failed to reach the purpose of prospecting, or did not thoroughly inspect the work and made a one-sided conclusion. In order to overcome this shortcoming, the census team of Northeast Branch and the small census team of each exploration team have carried out census and prospecting work in the past two or three years with the method of prospecting and prospecting combined with the regular regional geological survey in the periphery of each mine area. Practical results prove this
