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.

Tectonostratigraphic History of Mesopotamian Passive Margin during Mesozoic and Cenozoic, South Iraq. [PDF]

open access: yesKirkuk Journal of Science, 2008
Passive margin of Mesopotamian zone formed by two tectonic phases: opening and closing phases. Opening tectonic phase (Permian-Jurassic) represents the beginning of Wilson cycle. This phase includes three stages: pre-rifting, rifting and post-rifting. In

The Holocene temperature conundrum answered by mollusk records from East Asia

open access: yesNature Communications, 2022
Scientists have been puzzled by the disparity between climate simulations of the past 12,000 years and geological records. Dong et al. reconstructed past annual and seasonal temperatures from land snail records to examine the potential seasonal bias.

Tectonic evolution and differential deformation controls on oilfield water distribution in western Qaidam Basin

open access: yesShiyou shiyan dizhi, 2020
The impact of tectonic evolution and differential deformation on the distribution of oilfield water was discussed based on the analysis of tectonic kinematics and geometric characteristics of the western Qaidam Basin combined with the accumulation types ...

Variable Phase Relationship Between Monsoon and Temperature in East Asia During Termination II Revealed by Oxygen and Clumped Isotopes of a Northern Chinese Stalagmite

open access: yesGeophysical Research Letters, 2022
Termination II (T‐II) is a natural reference for evaluating the potential effect of substantial ice sheets melting on monsoon and temperature changes caused by global warming.

Additional records of decapod crustaceans from the lowerPleistocene beds of Poggi Gialli (Tuscany, central Italy)

open access: yesGeologija, 2020
Additional species of decapod crustaceans are recorded from the lower Pleistocene beds exposed at the Poggi Gialli quarries (Sinalunga, Tuscany, central Italy). They include Galathea tuscia sp. nov., Ilia sp., Liocarcinus cf. L. maculatus (Risso, 1827),

Cenozoic plate driving forces [PDF]

open access: yes, 1995
Past studies of plate driving forces have concluded that the forces due to subducted slabs in the upper mantle and those due to the thickening of the oceanic lithosphere are the principal driving forces. We reexamine the balance of driving forces for the

The latest geodynamics in Central Asia: primary and secondary mantle melting anomalies in the context of orogenesis, rifting, and lithospheric plate motions and interactions

open access: yesГеодинамика и тектонофизика, 2017
A comprehensive model for deep dynamics in Asia has been developed from the data on the evolution of melting anomalies in the context of lithospheric plate motions, interactions, orogeny, and rifting.

Alpine tectonic movements and salt tectonics of Eastern Ukraine

open access: yesВісник Харківського національного університету імені В.Н. Каразіна. Серія Геологія. Географія. Екологія, 2022
Within Eastern Ukraine, in the course of previous studies, neotectonic movements were established, caused by both salt tectonics and Attic (post-Miocene - pre-Pliocene) thrust dislocations of northeastern vergence.

THE KULTUK VOLCANO: SPATIAL-TEMPORAL CHANGE OF MAGMATIC SOURCES AT THE WESTERN TERMINUS OF THE SOUTH BAIKAL BASIN BETWEEN 18 AND 12 MA

open access: yesГеодинамика и тектонофизика, 2015
The Kultuk volcano erupted at the axial South Baikal basin of the Baikal rift zone (BRZ). Now it exhibits facies of subvolcanic bodies, land-lava eruptions and subaqueous pillow lavas and hyaloclastites.
