Hybrids of carbonate and terrigenous sediments Carbonate with terrigenous sediments are of characteristic from Emsian to Eifelian in stable shallow-sea faciesregion in Longmenshan area, and they can be classified evidently into hybrid Ⅰ and hybrid Ⅱ(Jingbaoshi-type). Type Ⅰ produced in mud shelf setting occupied hundreds of tempestite beds in which bottom cast、 hummocky cross bedding sandstones、 coquina were inter-beddded with shales that beared a great deal of verm traces、 bioturbations、 benthic communities dominative of brachiopods. Type Ⅱ in sand-mud-marl shelf was characterized by high-energy foreshore sandbeach facies and shelly bank facies.
