Permian tectonic switch of the southern Central Asian Orogenic Belt: Constraints from magmatism in the southern Alxa region, NW China

Open Geosciences
Late Paleozoic plutons are widely distributed in the Alxa region, southernmost Central Asian Orogenic Belt, and provided an important clue in constraint for the closing time of the Paleo-Asian Ocean (PAO). In this article, we present new zircon U-Pb ages

Seismogeological structure model of the Anabar-Olenek region

Georesursy
The velocity characteristics of the Upper Proterozoic-Phanerozoic sedimentary cover of the AnabarOlenek region were studied, in particular, the bimodal character of the distribution interval P-wave velocities was established.

Aligned hydrothermal fluid‐flow pathways in Middle Permian near‐shore marine sediments beneath a basaltic lava flow

Sedimentology, EarlyView.
ABSTRACT Tubular and curviplanar structures, outlined by the occurrence of haematite/goethite, chlorite, quartz and albite, are developed in the Middle Permian Broughton Formation in the southern Sydney Basin, New South Wales, Australia. These structures are interpreted as fluid‐flow pathways resulting from the ejection of heated pore fluids as a thick

Cooling and Exhumation History of the Paris Basin Southeastern Margin Revealed by Δ47 /U–Pb Carbonate Thermochronology

Terra Nova, EarlyView.
ABSTRACT This study applies Δ₄₇/U–Pb thermochronology to the Middle Jurassic carbonates exposed in the southeastern margin of the Paris Basin. By integrating clumped isotope analyses and U–Pb dating of diagenetic carbonates, we reconstruct the thermal and exhumation history of the sedimentary succession.

Comparison of Biofilm Growth and Quorum Sensing Molecules in Vaginal Lactobacillus Species: A Preliminary Report

Microbiology Research
Recently, studies suggest that the protective effects of Lactobacillus within the female reproductive tract may be partly due to their ability to form biofilms.

New Geochronological Constraints on the Late Palaeozoic Tarija Basin, Southern Bolivia: Tectonic and Palaeoclimatic Implications

Terra Nova, EarlyView.
ABSTRACT The Carboniferous‐Permian Tarija basin of southern Bolivia evolved under major tectonic and climatic influence. The timing of transition from glacially influenced to arid conditions, after the Gondwanide tectonic event, has been based mainly on palynological correlations.

P‐T‐t‐d Evolution of Low‐Grade Metamorphic Xenotime, Eastern Alps (Austria)

Terra Nova, EarlyView.
ABSTRACT In situ LA‐ICP‐MS U‐Pb dating of xenotime was used to establish the age of low‐grade metamorphism in Permian metasediments of the Austroalpine Unit (Eastern Alps, Austria). Complexly zoned xenotime in chloritoid‐bearing metasedimentary samples possesses distinct MREE‐rich domains. In the eastern sample, this domain yielded a date of c. 135 Ma,
