| Outline of Final Research Achievements |
We explored quartz composed of sand particles from the upper Cretaceous Djadokhta Formation in Mongolia, and poached dinosaur skeletons from Gobi desert. During 2015-2018, four dinosaur localities of the formation were researched, the geological mapping of these area was almost completed, and stratigraphy too. We focus on the variation in cathodoluminescence (CL) features of quartz grains extensively collected from the formation and poached dinosaur specimens, which can characterize each unit of the sediments by a spectral deconvolution method. Poached dinosaur skeletons stored in Institute of Paleontology and Geology, Mongolian Academy of Science can be estimated to occur in the formation. Therefore, this method employed by CL spectral analysis of quartz grains is expected for the provenance study of the fossils as well as stratigraphic investigation.
