摘要
The first member of the Qingshankou Formation recovered by CCSD-SK-Is borehole (China Cretaceous Continental Scientific Drilling-Songke-the south borehole) is oft-com:office:smarttags" />81.41 m long and 100% of cores recovery. The age of the member corresponds approximately to the Turonian. The sequence and process of lithology-lithofacies and cyclic stratigraphy were revealed by a detailed core description. Six rock types（mudstone, dolostone, marl, limestone, ostracode limestone and volcanic ash）comprise the sedimentary strata. Deposition occurred in a deep lake, including six sedimentary microfacies: dolostone, marl, limestone, deep lake turbidite
