Abstract The investigation of triggers causing the onset and intensification of Northern Hemisphere Glaciation (NHG) during the late Pliocene is essential for understanding the global climate system, with important implications for projecting future

Abstract Wind-blown dust from southern South America links the terrestrial, marine, atmospheric, and biological components of Earth’s climate system. The Pampas of central Argentina (~33°–39° S) contain a Miocene to Holocene aeolian record that

The formation of the Chinese Loess Plateau resulted from a combination of surface processes rather than from aridification of the Asian interior alone, according to zircon U-Pb geochronological analysis

Detrital zircon ages in Pleistocene sediments and wind erosion patterns indicate the Puna Plateau was dominated by westerly winds during intervals of high dust accumulation in the eastern subtropical Andes.

Wind changes the surface of the Earth, but the surface characteristics of the planet also impact the winds above it. Here, the authors propose a feedback process in which wind erosion in the western Gobi Desert alters the thermal properties of the su

Abstract Many applications specific to detrital mineral U‐Th‐Pb geochronology in the Earth sciences necessitate large numbers of age observations to be made from samples and require accurate and precise isotope measurements across wide dynamic ra

The 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 these

Despite decades of research, the mechanisms and processes of subduction initiation remain obscure, including the tectonic settings where subduction initiation begins and how magmatism responds. The Cretaceous Mawgyi Volcanics represent the earliest v

Loess sequences of the Chinese Loess Plateau (CLP) compose one of the most complete Neogene–Quaternary terrestrial paleoclimatic archives. Understanding the CLP's sediment sources is critical to tracing Asian aridification, atmospheric circulation
