一○五队所屬普查队,于1957年在辽西圍繞某矿区进行了面积达600多平方公里的1:25000的区域地質测量。其目的是想通过此次工作系統的解决区域内的成矿作用、火成活动、地层的詳細划分、構造变动和揭露与研究已知或新发现的矿化点,肯定其价值,以解决后备勘探基地问题。这兩个目的都是为了給某矿区的远景評价提供充分的根据。具体工作的要求和作法,一律采取经纬仪定点,每平方公里16个点,主要岩层及構造都进行槽探揭露并实測于图上,对标准地层要求有实測的标准剖面。
One hundred and fifty-five census-owned census teams conducted a 1: 25000 regional geological survey covering an area of over 600 square kilometers in 1957 in a mining area in western Liaoning. Its purpose is to affirm its value by systematically addressing the mineralization within the region, the volcanic activity, the detailed stratigraphic division, structural changes and the revelation and study of known or newly discovered mineralization sites systematically through this work Exploration base problems. Both of these aims are to provide ample evidence of the long-term evaluation of a mine. Specific requirements and practices of work, all to be sent to the theodolite fixed point, 16 points per square kilometer, the main rock formations and structures are exposed by trenching and measured in the map, the standard stratum requires a measured standard profile.
