The thermal history of the Western Irish onshore [PDF]

open access: yes, 2014
We present here a low-temperature thermochronological study that combines the apatite fission-track and (U + Th)/He dating methods with a pseudo-vertical sampling approach to generate continuous and well-constrained temperature–time histories from the ...

Peneplains and tectonics in North-East Greenland after opening of the North-East Atlantic

open access: yesGEUS Bulletin, 2021
Elevated plateaus with deeply incised valleys characterise elevated, passive continental margins (EPCMs) in all climate zones. These features are, however, a topic of debate regarding when and how the large-scale landscapes formed.

The first record of a paguroid shield (Decapoda, Anomura, Annuntidiogenidae) from the Miocene of Cyprus

open access: yesGeologija, 2020
For the first time, a paguroid shield is recorded from upper Miocene reefal strata (Koronia Member, Pakhna Formation) that crop out along the northern margin of the Troodos Massif, north of the village of Mitsero, Cyprus.

150 million years of freshwater fish biogeography: vicariance or dispersal? [PDF]

open access: yesResearch & Knowledge, 2017
Freshwater fishes are supposedly good case studies to test palaeobiogeographical models because they are attached to land masses, at least primary freshwater fishes, which are unable to cross marine barriers.

Stagnant slab front within the mantle transition zone controls the formation of Cenozoic intracontinental high-Mg andesites in northeast Asia

open access: yesGeology, 2020
The geochemistry of Cenozoic intracontinental high-Mg andesites (HMAs) in northeast Asia, together with regional geophysical data, offers an opportunity to explore the genetic relationship between the formation of intracontinental HMAs and subduction ...

A new species of Xyletinus Latreille, 1809 (Coleoptera: Ptinidae: Xyletininae) from Eocene Baltic amber, with a key to known fossil species [PDF]

open access: yesКавказский энтомологический бюллетень, 2021
A new extinct species of the genus Xyletinus Latreille, 1809, namely X. (s. str.) lobanovi sp. n., is described and illustrated from Eocene Baltic amber. This new extinct species resembles X.

Antarctic climate, Southern Ocean circulation patterns, and deep water formation during the Eocene [PDF]

open access: yes, 2017
We assess early-to-middle Eocene seawater neodymium (Nd) isotope records from seven Southern Ocean deep-sea drill sites to evaluate the role of Southern Ocean circulation in long-term Cenozoic climate change.

Discriminating cool-water from warm-water carbonates and their diagenetic environments using element geochemistry: the Oligocene Tikorangi Formation (Taranaki Basin) and the dolomite effect [PDF]

open access: yes, 2004
Fields portrayed within bivariate element plots have been used to distinguish between carbonates formed in warm- (tropical) water and cool- (temperate) water depositional settings.
