1973年新中国编制出版了第一部全国地质、矿产图集，并推动了若干省区地质图集和若干专业地质图集的出版。近30多年来，在改革开放的春风里，全国1：100万区域地质调查已完成国土面积98．6％，1：20万己完成95．8％。截止上世纪80年代，全国与分省地质图编制和地质总结相继完成；在矿产普查勘探、矿床、水文、海洋、深部、地震、灾害、环境等诸多地质领域，许多重要基础问题有所突破，科学积累极大丰富，重新编制新版地质图集是非常及时的(张宏仁，1996，总序)，大体和国际地图集的更新周期相近似。 相似文献

Preliminary Study on the Isotopic Age of Metamorphism and Anatexis of the Fuping Group of the Environs of Xiaojue, Pingshan County, Hebei Province CHENG Yuqi, WAN Yusheng and GAO Jifeng(Geological Institute, Chinese Academy Geological Sciences, Beijing, 100037) Part of the metamorphic rocks of the Early Precambrian Fuping Group of the study area have been subjected to differential anatexis shortly after the climax of regional metamorphism. Isotopic age studies of the zircons from both the metamorphic rocks and their anatectic derivatives by the single crystal U-Pb method have been carried out by the authors. The upper intercept age of the U-Pb concordia has been interpreted as the age of metamorphism or anatexis of the samples concerned. The results of the isotopic determination of zircons from the samples of three different rock types collected near Xiaojue and in the area further east(Fig. 1) give the age of regional metamor- 相似文献
