摘要
Neoproterozoic Xiamaling Formation reservoir of Qingbaikou System in Zhaojiashan area, Huailai County, Hebei Provence is a set of clastic rock depositions and the main lithology is grey green-gray black shale and iron-containing siltstone-fine sandstone. The geochemical characteristics are obvious in the formation and its value indicates a regular change as the sedimentary facies change. Based on the field observation and measurement, and combined with the slice data and geochemical analysis, it is considered that the sedimentary facies of Xiamaling Formation in Zhaojiashan area can be divided into shoreline facies and shallow-sea continental shelf facies, which can be further classified as three subfacies: onshore zone, transitional zone and offshore shelf. The sedimentary facies modes of Xiamaling Formation are summarized.
