七十年代以来,由于理解到早前寒武纪的花岗质岩石在地壳生长和演化过程中的重要作用而对其进行日益深入的研究。其中许多研究工作,都集中在西格陵兰、北美、南部非洲、西澳大利亚及芬兰的太古代克拉通上。迁安英云闪长岩-花岗闪长岩质片麻岩,出露在河北省迁安县的蟒山、龙虎山、塔山、石佛寺和青山院大贤庄一带,构成迁安断块隆起的核心。它的出现,标志着冀东太古代早元古代地壳演化中的大的地质阶段,因而引起研究者的注意(张贻侠等,1979)。
Since the 1970s, its understanding has been further studied because of its understanding of the important role played by the granitic rocks of the Precambrian during the crustal growth and evolution. Many of these research efforts are focused on the Pacific Kraton in West Greenland, North and South Africa, Western Australia and Finland. Qian’an-Ying diorite-granodiorite gneiss show in Qianshan, Longhushan, Tashan, Shifosi and Qianshanyuan Daxianzhuang, Qian’an County, Hebei Province, Core. Its appearance marked the great geologic stage in the Early Eastern Paleoproterozoic crustal evolution in the eastern part of Jidong, which attracted researchers’ attention (Zhang Yixia et al., 1979).
