Terrestrial Scientific Drilling Project of the Cretaceous Songliao Basin

 

Description

Songliao MapFigure: Location of Songliao Basin in tectonic framework of the northern China- Mongolia tract (NCMT). The NCMT, separated from Siberia by the Mongolia- Okhotsk suture zone, consists primarily of eastern and south-central Mongolia and northern and northeastern China, and is marked by the Yinshan-Yanshan belt on the south and by the Daxingganling belt on the east. YYF =Yilan-Yitong fault; DMF= Dunhua-Mishan fault; HSZ = Honam Shear Zone; B= basin; F = fault. (© Chengshan Wang)


Specific studies of the continuous borehole core (SK-I, II, and III) include:

  1. Biostratigraphy, chemostratigraphy and magnetostratigraphy and radiometric dating, to set up a high precision/resolution terrestrial stratigraphic framework (uppermost Jurassic-lowermost Paleogene) that can be correlated with global standard sequences.
  2. Temporal and climatic constraints on the evolution of Jehole Biota, tied to well document terrestrial signatures of the Cretaceous greenhouse.
  3. Biostratigraphic, isotope chemostratigraphic and magnetostratigraphic analyses (among others) to identify the terrestrial Jurassic/Cretaceous boundary, and to correlate with marine sequences in order to improve global stratigraphic correlation.
  4. Documentation of the terrestrial sedimentation response to major geological events and climate change from the beginning of Cretaceous, in order to identify potential causes of those changes and events.
  5. Investigation of the relationship between paleoclimate changes and deposition of major terrestrial hydrocarbon source rock intervals during the Cretaceous. As one of the world's most significant terrestrial oil-bearing basins, the Songliao Basin should be a good recorder of major carbon cycle events, such as those associated with Cretaceous oceanic anoxic events. The objective is to illustrate the relation between hydrocarbon precursor formation and the carbon cycle in terrestrial settings.
  6. Undertaking integrated study of the major Cretaceous geological events and greenhouse climate change in order to reconstruct paleoclimate during important periods of the Cretaceous in Asia.
