Late Lower and Middle Devonian miospores from Saudi Arabia [PDF]

Review of Palaeobotany and Palynology, 1995
Abstract Late Lower and Middle Devonian miospores are identified in cuttings from well TRBH-1. A biostratigraphic zonation is proposed and compared with the miospore zonal scheme defined in Western Europe. All samples contained caved material. By graphic correlation with contemporaneous cored sequences previously analysed in Libya and Tunisia, the ...

Conellae, enigmatic structures on cephalopod shells—shapes, distribution, and formation [PDF]

, 2019
Conellae, enigmatic cone-shaped structures which can be found on the surface of internal moulds of cephalopod shells (predominantly of ammonoids), are regarded herein as the product of remote (biologically induced) biomineralization formed in closed-off ...

The role of sea-level change and marine anoxia in the Frasnian-Famennian (Late Devonian) mass extinction [PDF]

, 2008
Johnson et al. (Johnson, J.G., Klapper, G., Sandberg, C.A., 1985. Devonian eustatic fluctuations in Euramerica. Geological Society of America Bulletin 96, 567–587) proposed one of the first explicit links between marine anoxia, transgression and mass ...

Deep Groundwater Total Dissolved Solids Mapping in the Dakota Group, Williston Basin, USA

Groundwater, EarlyView.
Abstract Growing concern about the quantity of available freshwater around the world has led to interest in surveying groundwater total dissolved solids (TDS) below water well depths. Deep TDS has not been systematically mapped, and there is much to learn about the distribution and controls on deeper groundwater. In sedimentary basins across the United

Bimekizumab efficacy using IHS4 outcomes in hidradenitis suppurativa: Results from BE HEARD I and II

Journal of the European Academy of Dermatology and Venereology, EarlyView.
The majority of bimekizumab‐treated patients shifted from severe to mild and moderate IHS4 stages, and nearly 25% achieved an IHS4 of 0 by Week 48. Bimekizumab led to clinically meaningful improvements across IHS4 outcome measures. These data highlight an opportunity to address the need for effective treatments against draining tunnels.

Garnet–Clinopyroxene Double‐Layered Coronae in a Metagabbronorite From the High‐Grade Metamorphic Gföhl Unit, Moldanubian Zone

Journal of Metamorphic Geology, EarlyView.
ABSTRACT This study investigates garnet–clinopyroxene double‐layered coronae in a metagabbronorite from the high‐grade metamorphic Gföhl Unit (Bohemian Massif). The coronae formed at the interfaces between relic magmatic orthopyroxene, still preserved in the cores of the coronae, and the plagioclase‐rich rock matrix.
