ABSTRACT Complex stratigraphic arrangements may be generated through lateral facies transitions from the strata of aeolian depositional systems into bordering peritidal deposits. In such scenarios, sedimentary architectural complexity and associated facies heterogeneities are governed by the interplay between autogenic processes inherent to tidal ...

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.

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)
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,
