AbstractReconstruction of Aptian–Albian paleoclimate obtained from marine records remains a challenging topic, but studies on coeval terrestrial paleoclimate and trigger mechanisms have lagged substantially. In this study, new multiproxy data from mudr…
AbstractEarly microbial gas has been sealed in reservoirs in the Miquan region of NW China, with little or no supply of current microbial gas. To date, the environmental conditions and mechanisms restricting microbial methanogenesis are still unclear i…
AbstractA high-resolution time series of diatoms from the Estancia Basin of central New Mexico, USA, reveals decadal to millennial changes in water chemistry during the Last Glacial Maximum (LGM) and suggests that groundwater leakage limited the size o…
AbstractThe Pampas of Argentina contain a broad distribution of Pleistocene to Holocene loessic sediments and eolian dune deposits. Models describing the sediment provenance of this eolian system have, at times, conflicted. We address the provenance of…
AbstractSpatiotemporal constraints for Late Cretaceous tectonism across the Colorado Plateau and southern Rocky Mountains (northern Arizona–New Mexico, USA) are interpreted in regards to Laramide orogenic mechanisms. Onset of Laramide arch development …
AbstractThe Tarim craton in modern Central Asia was an important component of the supercontinent Rodinia in the Neoproterozoic, although its paleogeography in Rodinia during that era is still controversial. Here, we present new stratigraphic, geochemic…
AbstractDiverse Neoarchean granitoid assemblages, which generally include tonalites–trondhjemites–granodiorites (TTGs) and various K-rich granitoids, are prevalent in most basement terranes of the North China Craton. However, the Hengshan terrane is an…
AbstractAlthough high-Mg andesites (HMA) have attracted increasing attention due to their unique geochemical composition and important geological significance, there is no consensus on their petrogenesis. The present study indicates that the subducting…
AbstractSouth China, India, and their derivative blocks preserve many similar magmatic and sedimentary records related to the tectonic transition from Rodinia to Gondwana. They provide crucial insights into not only the paleogeographic correlation betw…
AbstractThe present topography of the northern Tibetan Plateau is characterized by the northwest-trending Eastern Kunlun Range, Qaidam Basin, and Qilian Shan, which figure importantly into the evolution and mechanism of Tibetan plateau development duri…
