SIN ACHIEVEMENT ASO PROGRESS OF THE BASIC GEOLOGICAL RESEARCH OVER LAST TEN YEARS IN EASTERN SHANDONG REGION

摘要:

十多年来，鲁东地区先后开展并全面完成了新一轮１：２０万区调修测工作，１∶５万区调覆盖面积已达６０％以上。与此同时，还开展了一系列的专题研究和成果总结．由于广泛应用了区调工作新理论、新方法和新的技术手段，因此使得该区基础地质研究程度大大提高，地质图件面貌发生了重大改观。本文依据这些新成果，对鲁东地区十多年来基础地质研究取得的主要进展作一初步总结。内容涉及前寒武纪变质地层及中生代陆相地层的划分、变质变形花岗质片麻岩（体）及玲珑复式岩体、区域变形构造及鲁东碰撞带研究等几个方面。
