    The determination of the middle Jurassic strata in Xiushui area, northern Liaoning Province, and its geological significance

    • Through basic geological investigation of oil and natural gas, the authors studied the data of drill holes, lithologic assembly and paleontology fossils for a coal-bearing rock formation distributed along the Xiushui River. The result indicates that the geological age of the coal-bearing rock formation is Middle Jurassic, and the stratigraphic horizon is correlated with Haifanggou Formation in western Liaoning Province. The confirmation of the geological age of this coal-bearing rock formation offers important information for studying tectonic evolution and searching for the bed of source rock in the prospecting for oil and natural gas.
