  1. 1. Climate and vegetation during the Miocene - evidence from Danish palynological assemblages

    Författare :Linda Larsson; Berggrundsgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; palaeoenvironment; pollen; climate; Denmark; palynology; Miocene;

    Sammanfattning : Several Danish exposures and one drill core spanning the upper Oligocene-upper Miocene interval of the Cenozoic (i.e., 24–5 Myr ago) were palynologically investigated. LÄS MER

  3. 2. Latest Miocene – Early Pliocene Paleoclimate and Phytoplankton Productivity

    Författare :Boris-Theofanis Karatsolis; Jorijntje Henderiks; Luc Beaufort; Uppsala universitet; []
    Nyckelord :Late Miocene; early Pliocene; IODP; paleoclimate; basin evolution; phytoplankton; paleoproductivity; Milankovitch cycles; Earth Science with specialization in Historical Geology and Palaeontology; Geovetenskap med inriktning mot historisk geologi och paleontologi;

    Sammanfattning : Paper IPre-Quaternary paleoclimate studies in Australia mainly focus on terrestrial records from the southeastern part of the continent. IODP Expedition 356 drilled on the northwestern Australian shelf, yielding Miocene-Pleistocene paleoclimate records in an area where climate archives are scarce. LÄS MER

  4. 3. The metamorphic history of Naxos (central Cyclades, Greece) : Deciphering the Oligocene and Miocene exhumation events

    Författare :Alexandre Peillod; Uwe Ring; Alasdair Skelton; Arne Willner; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cycladic Blueschist Unit; exhumation; fluid flow; geothermobarometry; Hellenide orogen; Rb-Sr dating; subduction-zone metamorphism; Heat flow; Lower crust; extensional domain; Metamorphic core complex; Geology; geologi;

    Sammanfattning : High pressure, low temperature (HP-LT) rocks observed at the surface of the Earth are evidence ofpast subduction zones. Understanding the tectonics processes that control the exhumation of HP-LT metamorphic rocks in these subduction zones requires full comprehension of the pressure-temperature-time (P–T–t) cycle that the rocks experienced.

  7. 5. Late Miocene to Pliocene orbital and climatic forcing on marine productivity

    Författare :Boris-Theofanis Karatsolis; Jorijntje Henderiks; Thomas Stevens; David De Vleeschouwer; Clara T. Bolton; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The late Miocene to Pliocene was a geological time interval of global cooling, albeit in a warmer-than-present world, which is commonly used as a past analogue for future anthropogenic climate change. The investigation of marine sediments recovered by the International Ocean Discovery Program (IODP) sheds light on different paleoclimatic, paleoceanographic and paleobiological characteristics of this period.
