一、基础地质研究方面1.第二代青海省地质图(1:100万);系统地总结和反映了自1972年第一代青海省地质图(1:100万)出版后的区城地质调查、矿产普查和专题研究成果。由于采用了新编的1:100万地理底图,提高了地质内容的表现精度;根据1:100万地质路线资料并结合卫星照片解译成果,填补了我省北部、西部和南部边缘地区地质工作空白区;对地层分区、地层单位、构造内容和岩体形态作了部分补充修订;应用同位素年龄数据等资料,为划分古老地层和侵入岩分期提供了较充分的依据。地质图图面清晰,结构合理,内容丰富,是一综合性较强的基础性地质图件。该图附有说明书,对全省地层、岩浆岩、构造等基本特征及研究现状,作了较全面系统的论述。第二代青海省地质图(1:100万)及说明书出版后,可提供地质生产、科研、教学等部门广泛使用。
I. Basic Geological Research 1. The second generation of geological map of Qinghai Province (1: 1 million); systematically summarizes and reflects the geology of the district city since the first generation of geological map of Qinghai Province (1: 1 million) was published in 1972 Investigation, mineral survey and special research results. Due to the newly compiled 1: 1 million geographic basemaps, the accuracy of the geological contents has been improved. According to the geological route data of 1: 1 million and interpretation of satellite photos, the geology of the northern, western and southern margins of the province has been filled Blank area of work; some revisions were made to the stratigraphic division, strata units, structural contents and rock mass morphology; the application of isotopic age data and other data provided more sufficient basis for dividing the stratum of ancient and intrusive rocks. Geological map clear, reasonable structure, rich in content, is a comprehensive strong basic geological map. Attached to the map with the instructions, the province’s strata, magmatic rocks, the basic characteristics of the structure and research status, made a more comprehensive and systematic exposition. The second generation of Qinghai Province geological map (1: 1 million) and the specification is published, it can provide geological production, research, teaching and other departments widely used.
