    Folding of the middle-upper Proterozoic Jianshan Formation of Baiyunebo Group is very complex in Huaguoshan area of southeast Baiyunebo, northern margin of North China Platform. In order to study the shapes of folds and their deformation mechanism, 1/2000 scale geological mapping has been made in an area of 1 km 2. Two stages of folding have been defined based on distribution of metamorphic feldspathic quartz sandstone.
