| Abstract: | The Luohanci rock group lies in the Shangxian Danfeng structural belt within the major suture zone between the North China Plate and the Yangzi Plate. Regionally, it is clipped as structural microlithon within the Shangxian Danfeng structural belt, with an extension about 100 km from the east to the west continually. The special structural location of the group has indicated that determination of the group age has a great significance for researches of the regional tectonics. The geological characteristics, the age and the geological significance of the rock group are discussed in this paper from the aspects of lithostratigraphy, lithology, geochemistry and isotopic ages. |
