1. No. 1 Institute of Geological and Mineral ��esources Survey��Henan Bureau of Geo- exploration �� Mineral Development�� Luoyang 471000��Henan��China; 2. Department of Land and ��esources of Henan Province��Zhengzhou 450007��China
Previously��the stratigraphic unit of clastic and carbonate rocks overlying the Xiong'er Group had been divided into the Gaoshanhe Group and the Longjiayuan Formation of Guandaokou Group�� Through the profiling and regional correlation��the authors found that the unit actually consists of the Yunmengshan- Luoyukou formations of ��uyang Group of Changcheng System��the Huanglianduo Formation of Jixian System��and the Luoquan- ��Xinji- �� Zhushadong- �� Mantou formations of Cambrian System�� Meanwhile�� Gymnosolen and Cabbage type stromatolites have been found in the Huanglianduo Formation��which can be compared with the stromatolites of Longjiayuan- Xunjiansi formations of Guandaokou Group�� The fact confirms that the Guandaokou Group and Huanglianduo Group belong to the same set of carbonate sediments in the southern margin of the North China Craton formed in the Jixianian Pe- riod��
