Abstract The Beishan orogen is part of the Neo-proterozoic to early Mesozoic Central Asian Orogenic System in central Asia that exposes ophiolitic complexes, passive-margin strata, arc assemblages, and Precambrian basement rocks. To better constrain tectonic evolution orogen, we conducted field mapping, U-Pb zircon dating, whole-rock geochemical analysis, Sr-Nd isotopic analysis. new results, w...

The voluminous Triassic magmatism within the Lhasa Terrane, Tibetan Plateau, has been studied for decades yet petrogenesis of magmas involved and tectonic setting this associated events remain uncertain. This study presents new zircon U–Pb geochronological, Lu–Hf isotopic, whole-rock geochemical data Middle volcanic rocks southern region terrane. Zircon dating three samples from area yield cons...

A micropaleontological study has been carried out on the samples collected from the Sarv Abad section, the oldest and only known Jurassic sedimentary rocks cropping out in the Moghan area. Studied sequence consists of carbonates bounded at both base and top by clastic deposits. Studied carbonate deposits provide an assemblage of benthic foraminifera as well as calcareous algae. The stratigraphi...

The Turonian–Coniacian continental fossil record in Europe is scarce. Here we present a new assemblage of early Coniacian age that was systematically collected from the coal-bearing Gosau Group Tiefengraben locality near St. Wolfgang, Austria. diverse composed at least 60 taxa including sporomorphs and Normapolles-related pollen, seeds leaves angiosperms gymnosperms, charophytes, gastropods, bi...

A detailed study of calcareous nannofossil assemblages from twelve uppermost lower Barremian–lower Aptian sections in the Subbetic Domain Betic Cordillera was performed. Seven new species (Crucibiscutum bastetanum, Crucibiscutum gracile, Chiastozygus lamprostauros, Cyclagelosphaera platyaspis, Lithraphidites aichmoides, pugio, and Rhagodiscus sicutclipeus) are described, one is emended (Lithrap...

Deposits spanning the Radotruncana calcarata Taxon Range Zone at the Postalm section, Northern Calcareous Alps (Austria) are examined quantitatively for foraminiferal assemblages, especially the planktonic group. This study focuses on establishing a high resolution record spanning an 800 ka long stratigraphic interval from the active continental margin of the Penninic Ocean. The Postalm section...
