Members of the team also have ongoing work on the benthic macro- and micro-fossil palaeoecology prior, during and after a major period of ocean de-oxygenation that occurred about Ma ago in the Jurassic (see also ocean deoxygenation theme). The macrofossil benthic assemblages changed drastically during the event with only extreme. In the present study dinoflagellate cyst events (first and last occurrences) combined with changes in organic-carbon-isotope (δ 13 C org) stratigraphy are demonstrated to be good indicators for assessing the mid-Cretaceous Stage and Substage boundaries in by: 7.
(first and last occurrences) can even be traced globally (Leereveld, ; Oosting et al., in prep.; Chapters 2, 3, and 4). Moreover, quantitative dinocyst records register palaeoenvironmental and climatic changes, because they are sensitive to changes in the marine environment, like in sea-. Scope and outline of the thesis: With the aim set for this study, the European sequence chosen as reference for global correlation is the Barremian type section at Angles, SE France (Birkelund et al., ). Various studies on this section, which contains a Barremian-Aptian transition interval, have already described its ammonite stratigraphy (Delanoy, ), δ13C isotope stratigraphy Cited by: 7.
Neanderthals and Modern Humans develops the theme of the close relationship between climate change, ecological change and biogeographical patterns in humans during the Pleistocene. In particular, it challenges the view that Modern Human 'superiority' caused the extinction of the Neanderthals between 40 and 30 thousand years by: Tibet sediments reveal climate patterns from late Miocene, six million years ago More information: Dominant ,year precipitation cyclicity in a late Miocene lake from northeast Tibet.

Members of the team based at the Open University who research palaeoenvironmental change have a long-standing reputation for the reconstruction of past environments from biological, chemical and physical measurements in sedimentary deposits and other natural archives.
We are using these measurements and archives to advance our knowledge of. The Huguang maar lake (21°9′N, °17′E, Fig. 1) is situated in a zone with seasonal climate, dominated by the East Asian summer monsoon, but also within reach of northern cold waves during winter which originate from the Siberian anti-cyclone (Domrös and Peng, ).It is influenced by both the Asian SW and SE summer monsoon and receives precipitation from the pre-summer position of Cited by: High-resolution Last Glacial Maximum to Holocene palaeoenvironmental changes corresponding to a time interval between and years are examined in the Myrtoon basin in the SW Aegean Sea, using the abundance variation in foraminifera and pollen in relation to accelerator mass spectrometry 14 C dating and limited oxygen isotope data.

Asia - Asia - Geologic history: Asia is not only Earth’s largest continent but also its youngest and structurally most-complicated one. Although Asia’s evolution began almost four billion years ago, more than half of the continent remains seismically active, and new continental material is currently being produced in the island arc systems that surround it to the east and southeast.
