A NEW DINOSAUR TRACKSITE IN THE LATE ALBIAN OF ISTRIA, CROATIA

Rivista Italiana di Paleontologia e Stratigrafia, 2007
A new site with dinosaur footprints has been found in the upper Albian sediments of Istria, Croatia. The site was discovered near the city of Pula, at the Zlatne Stijene locality.

Feldspar Albitization With Implications for Reservoir Quality Evolution of Eocene Turbidite Sandstones in Offshore Espírito Santo Basin, Eastern Brazil

Journal of Petroleum Geology, EarlyView.
ABSTRACT The diagenetic albitization of plagioclase and K‐feldspar grains is a transformative process that significantly alters sandstone's detrital composition and formation water chemistry, impacting reservoir quality. In this study, Eocene turbidite sandstones from the offshore Espírito Santo Basin, Brazil, were investigated to elucidate the role of

Processes and Patterns of Dolomite Precipitation in Aptian Pre‐Salt Deposits of Santos Basin, Brazil

Journal of Petroleum Geology, EarlyView.
ABSTRACT The Aptian pre‐salt lacustrine carbonates represent the most significant oil exploration target along the South Atlantic margin. Dolomitization of the Santos Basin Barra Velha Formation (BVF) is critical for reservoir quality, yet its origin, patterns, and evolution remain poorly understood.

Albian syndepositional block rotation and its geological consequences, Basque–Cantabrian Basin (western Pyrenees)

, 2013
Stratigraphic, structural, palaeocurrent and palaeomagnetic analyses of Upper Albian deep-water deposits in and around the Deba block (Northern Iberia) are presented. Results indicate an anticlockwise vertical-axis rotation of this block by 35◦ during a

Umbria-Marche Basin, Central Italy: A Reference Section for the Aptian-Albian Interval at Low Latitudes

Scientific Drilling, 2012
Within the Cretaceous Period, the Aptian-Albian interval (125–99.6 Ma, Ogg et al., 2008) was a critical time on a global scale. This is evident from 1) changes in the nature of the ocean-climate system brought about by increased ocean crust production ...

Evolution in arid environments: the role of betalains, succulence, and medullary bundles

New Phytologist, EarlyView.
Overview of the study system. Summary The flowering plant clade Caryophyllales includes many succulent species that grow in drought conditions. Many Caryophyllales species also have betalain pigmentation and medullary bundles, both of which have been linked to stress tolerance, albeit with less precise functional characterisation.

Drowned carbonate‐rimmed margin controlling shelf‐edge delta progradation and sedimentation dynamics: Upper Cretaceous Woodbine Formation, Texas, USA

Sedimentology, EarlyView.
ABSTRACT Shelf‐edge deltas are commonly interpreted to record basinward facies migration across uninterrupted, gently dipping shelf margins; however, examples from mixed siliciclastic‐carbonate margins reveal more complex depositional dynamics. Periods and areas of carbonate sedimentation within mixed siliciclastic‐carbonate margins can modify shelf ...

X-ray computed microtomography as a fundamental piece in the study of microcrinoids

Acta Palaeontologica Polonica
This study employs X-ray computed microtomography (micro-CT) to investigate the internal structures of microcrinoids, focusing on the roveacrinid Sergipecrinus reticulatus from the Aptian–Albian (112–115 Ma) of the Sergipe Basin, Brazil.
