New remains and paleoecology of uruguaytheriine astrapotheres (Mammalia) from the Middle Miocene of Bolivia [PDF]

Acta Palaeontologica Polonica
Astrapotheres (Astrapotheria) are an order of South American native ungulates (SANUs), and the geologically youngest astrapotheres belong to the subfamily Uruguaytheriinae (Astrapotheriidae).

Replacement of Ores Recorded by Textures and Chemical Compositions of Sphalerite: An Example From the Furutobe Kuroko Deposit, Akita, Japan

Geological Journal, EarlyView.
Coupled dissolution‐reprecipitation of early formed Cd‐, Fe‐, Ag‐ and Sb‐poor sphalerite through interaction with high‐temperature and high‐sulphur fugacity Cu‐rich fluids, responsible for the formation of the yellow ores, resulted in the formation of Cd‐, Fe‐, Ag‐ and Sb‐rich, heavily chalcopyrite‐diseased sphalerite and enrichment of critical metals ...

Thermochronologic Constraints on the Extensional History of the Ibex Hills, Southeastern Black Mountains, Death Valley, California

Geological Journal, EarlyView.
A. Modeled T‐t paths for samples in the northern Ibex Hills, showing steady cooling throughout much of the Cenozoic, until rapid Miocene cooling. B. Weighted mean paths for each sample in this study. Note that all show a rapid cooling event at or just after 10 Ma, which is interpreted to represent exhumation as a result of regional extenstion ...

Geoenergy potential of the Croatian part of Pannonian Basin: insights from the reconstruction of the pre-Neogene basement unconformity

Journal of maps, 2019
Presented work focuses on the importance of unconformity that separates the Neogene infill from older Palaeozoic and Mesozoic rocks in the Croatian part of Pannonian Basin.

Paleogene – Neogene

During the late Danian-Selandian Laramide phase, open-marine carbonate deposition of the Late Cretaceous and earliest Paleocene was replaced by clastic sediment infll of the Southern North Sea Basin. The Laramide phase, associated with domal uplift and subsidence of Mesozoic grabens, led to a break in sedimentation and reworking of Upper Cretaceous ...

Notable Impact of Paleotectonic Stress on Gold Mineralisation in the West Qinling Orogen

Geological Journal, EarlyView.
By applying fuzzy clustering and multiple inverse methods, we systematically processed the data of vein and fault slip in this ore deposit to reveal the transition of orogenic geological environment and paleotectonic stress field. Our research results show two different stress states: the northwest–southeast extensional stress field and the northeast ...

Geomorphology of the northern sector of the Alfambra-Teruel depression (Iberian ranges, NE Spain)

Journal of Maps, 2019
The area of Alfambra (NE Spain) is very representative of the relief evolution of the Eastern Iberian ranges. The geomorphological cartography (Main Map) includes the northern sector of the Alfambra-Teruel Neogene depression and its mountainous ...

The Neogene lakes on the Balkan land [PDF]

Geološki Anali Balkanskoga Poluostrva, 2012
Palaeogeographic maps of the lacustrine Miocene and Pliocene have been constructed according to all the known geological data. The Lakes of the Balkan Land, depending on the tectonics, migrated due to causes from the deep subsurface.
