Based on a regional geological survey at a scale of 1:50000, it reveals that the volcanic rocks from the Baiyin'gaolao Formation of Gaoyaowula in Inner Mongolia could be divided into three lithologic segments by the triple mapping method of "volcanic ...

Biohermal structures exploration of the Pre Upper Permian sedimentary rocks of the northern part of the Buzachi Peninsula and the neighbouring shelf area of the Caspian Sea [PDF]
A detailed lithological and stratigraphical analysis of poorly studied Pre Upper Permian sedimentary section uncovered by deep wells on the Buzachi Peninsula is carried out. The characteristic lithological strata are distinguished.

Tectonic significance of changes in post-subduction Pliocene-Quaternary magmatism in the south east part of the Carpathian-Pannonian Region [PDF]
The south-eastern part of the Carpathian–Pannonian region records the cessation of convergence between the European platform/Moesia and the Tisza–Dacia microplate.

Post-collisional Tertiary–Quaternary mafic alkalic magmatism in the Carpathian–Pannonian region: a review [PDF]
Mafic alkalic volcanism was widespread in the Carpathian–Pannonian region (CPR) between 11 and 0.2 Ma. It followed the Miocene continental collision of the Alcapa and Tisia blocks with the European plate, as subduction-related calc-alkaline magmatism was

Modeling pN2 through Geological Time: Implications for Planetary Climates and Atmospheric Biosignatures [PDF]
Nitrogen is a major nutrient for all life on Earth and could plausibly play a similar role in extraterrestrial biospheres. The major reservoir of nitrogen at Earth's surface is atmospheric N2, but recent studies have proposed that the size of this ...

Explosive volcanism resulting in stratospheric injection of sulfate aerosol is a major driver of regional to global climatic variability on interannual and longer timescales. However, much of our knowledge of the climatic impact of volcanism derives from

Explosive volcanism as a key driver of the late Paleozoic ice age
Atmospheric CO2 exerts a robust and well-documented control on Earth’s climate, but the timing of glaciation during the late Paleozoic Ice Age (LPIA; ca. 360–260 Ma) is inconsistent with pCO2 reconstructions, hinting at another factor.
