Geochemistry and Geochronology of Magmatic Rocks in Southwestern and Northeastern Cambodia: Implications for the Tectonic Evolution and Metallogenesis of the Loei Fold Belt

Geological Journal, EarlyView.
The composition of intrusive rocks suggests that the magma was likely generated in a subduction‐related setting. The arc crustal thickness in the Phnom Sro Ngam and Halo Prospects was probably < 40 km during emplacement. Zircon U–Pb age range indicates a correlation with Loei Fold Belt magmatic activity.

The Effect of Managerial Ability on the Market Valuation of Unrecognized Tax Benefits

American Business Review
This study examines the effect of managerial ability on the market valuation of unrecognized tax benefits (UTBs). While UTBs are generally associated with significant risks, we hypothesize that highly able managers can enhance the market valuation of the

Early Permian crinoids from Laurasia and their paleogeographic implications [PDF]

Acta Palaeontologica Polonica
A new crinoid fauna is described from the Trogkofel Group of the Southern Karavanke Mountains, Slovenia (lower Permian, Artinskian). This fauna is from a shallow platform or upper slope setting and is comprised primarily of isolated aboral cups.

Permian

The Permian System in the Netherlands is subdivided into the Lower Rotliegend, Upper Rotliegend and Zechstein groups. These groups were deposited in a large epicontinental basin extending from the UK to Poland. The Lower Rotliegend Group, deposited during the early Permian, unconformably overlays older strata (at the Base Permian Unconformity), is ...

The Permian Bacterium that Isn't

Molecular Biology and Evolution, 2001
There is growing evidence for the presence of viable microorganisms in geological salt formations that are millions of years old. It is still not known, however, whether these bacteria are dormant organisms that are themselves millions of years old or whether the salt crystals merely provide a habitat in which contemporary microorganisms can grow ...

Environmental Contaminant Accumulation in Freshwater Turtles Inhabiting Three Rivers of the Permian Basin, New Mexico, USA

Environmental Toxicology, EarlyView.
ABSTRACT Freshwater turtles are valuable sentinels of aquatic systems due to their long lifespans and resilience in environments impacted by contaminants. The Permian Basin, dominated by the oil and gas sector, spans western Texas and southeastern New Mexico, USA, including the Pecos River and its tributaries, the Delaware and Black Rivers.

Vancomycin-induced Severe asymptomatic Immune Thrombocytopenia; a rare cause

Southwest Respiratory and Critical Care Chronicles, 2014
Drug-induced immune thrombocytopenia is a challenging clinical problem that is often overlooked. Vancomycin is a rare cause of immune-mediated thrombocytopenia that can cause severe life-threatening bleeding in an acutely ill patient.

The Material Basis of 18th‐Century Meissen Porcelain

Archaeometry, EarlyView.
ABSTRACT In the summer of 1708, the quest for making hard‐paste porcelain from Saxonian clay and other mineral resources succeeded. This was achieved by applying as its essential ingredient newly discovered pure kaolin from Heidelsberg near Aue, western Saxon Ore Mountains.
