Carbonates from Santos Basin revealed U–Pb ages correlated with basalt ages (A), suggesting that they were formed during magmatic events. These events placed hot CO2 in the reservoir, which, when mixed with carbonate‐rich cold water (B), led to thermal convection, enabling the formation of the U contained in the carbonates.

Palaeobathymetry of the Abderaz Formation using foraminifera, Iran [PDF]
Abderaz Formation at its type section with an age of Turonian-early Campanian and a thickness of 300 m contains light grey shale and marl. The study of the planktonic foraminifera in isolated form led to differentiate three morphotype groups.

Faunal change in Cretaceous endemic shallow-marine bivalve genera/subgenera of the northeast Pacific [PDF]
Endemic shallow-marine Cretaceous bivalves in the northeast Pacific region (NEP), extending from southwestern Alaska to the northern part of Baja California Sur, Mexico, are tabulated and discussed in detail for the first time.

What, if anything, is a Paratrochamminoides? A key to the morphology of the Cretaceous to Cenozoic species of Conglophragmium and Paratrochamminoides (Foraminifera) [PDF]
We present a review of the current taxonomical status of the genus Paratrochamminoides Soliman, 1972. We recognise five main subgroups of this genus based upon the following modes of coiling: trochospiral, streptospiral, glomospiral, triloculine or ...

Geology and Jurassic paleogeography of the Mt. Primo-Mt. Castel Santa Maria ridge and neighbouring areas (Northern Apennines, Italy) [PDF]
This paper presents the results of a geological mapping project across the Mt. Primo ridge and neighbouring areas (Umbria-Marche Domain – Northern Apennines), where a thick Meso-Cenozoic carbonate succession is exposed.

This study reports two isolated feather fossils from the Lower Cretaceous Dabeigou Formation in northeastern China. Morphological analyses identified them as the earliest known feathered theropods (potentially including avian) in the Jehol Biota. This finding reveals a complex ecosystem at the dawn of the Jehol Biota, bridging the temporal and faunal ...

Faulting patterns in the Lower Yarmouk Gorge potentially influence groundwater flow paths [PDF]
Recent studies investigating groundwater parameters, e.g., heads, chemical composition, and heat transfer, argued that groundwater flow paths in the Lower Yarmouk Gorge (LYG) area are controlled by geological features such as faults or dikes.

Taxonomy and biostratigraphy of new and emended species of Cenozoic deep-water agglutinated foraminifera from the Labrador and North Seas [PDF]
Deep marine, fine grained sedimentary strata of Maastrichtian through Miocene age in the Labrador and North Sea sedimentary basins are rich in agglutinated benthic foraminifera.

Sedimentary processes and architecture of Upper Cretaceous deep-sea channel deposits : a case from the Skole Nappe, Polish Outer Carpathians [PDF]
Deep-sea channels are one of the architectonic elements, forming the main conduits for sand and gravel material in the turbidite depositional systems.
