Lake Pannon covered the area of the Pannonian Basin during the Late Miocene. Because of its wide-range distribution, economic importance and unique, mostly “caspi-brackish” endemic biota, its lacustrine deposits have attracted much scientific attention in the past hundred years. According to the latest stratigraphic division accepted for the area and bioprovince of the Western or Central Parate...

The fossil remains of euryhaline organisms in the Mesozoic±Cenozoic, non-marine sedimentary records of eastern China may have resulted from either marine transgressions or inland hypersaline lacustrine environments. Paleontological and organic geochemical results of this study have provided new evidence for marine transgressional events in the gigantic freshwater lake Songliao during the late C...

The organic-rich shale of the Upper Cretaceous Qingshankou Formation is an important hydrocarbon source rock in Northeast China. In this study, taking lacustrine as example, geochemical analysis, including total organic carbon (TOC), Rock-Eval pyrolysis, maceral compositions, X-ray diffraction (XRD), and biomarker analyses, were carried out on twenty-four samples to evaluate geochemistry enviro...
