摘要

Based on the detailed description on the cores from the second member bottom of Nenjiang Formation to the third member top of Quantou Formation in CCSD-SKⅡ, the core profile was established, and five common lithology (mudstone, silty mudstone, mudy siltstone, siltstone and sandstone) and eight special lithology(dolomite, volcanic ash, oil shale, lime mudstone, marlite, recrystalline limestone, ostracode clastic limestone and ostracode limestone) were identified. 172 layers of special lithology in CCSD-SKⅡ were recognized with a total thickness of 14.516m.
