The ubiquitous occurrence of glycerol dialkyl glycerol tetraethers (GDGTs) in soils and their ability to record temperature and environmental changes offer the prospect of independently reconstructing continental paleotemperature and paleoenvironment from the loess-paleosol sequences (LPS) from the Chinese Loess Plateau (CLP). In this study we present records of GDGT-derived proxies for the las...

Detailed vegetation history response to complex influencing factors of arid Central Asia (ACA) is crucial understanding ecological sustainability. Here, we present the first pollen record in Ili Valley during Last Glacial Maximum (LGM) using Jirentai (JRT) loess-paleosol sequence. Combining results multi-climate proxies and optically stimulated luminescence (OSL) dating, aim reconstruct vegetat...

Red clayey paleosols that are chiefly the product of aerosolic dust deposition are interbedded in the Quaternary carbonate formations of the Bermuda oceanic island system. These paleosols provide a basis for reconstructing Quaternary atmospheric circulation patterns in the northwestern Atlantic. Geochemical analyses were performed on representative paleosol samples to identify their parent dust...

Upper Triassic sedimentary systems of both the Arabian Plate and Germanic Basin reveal climate- plate tectonic-forced effects through certain time-intervals experienced by architectural elements, lithofacies types, unconformities, flash flood deposits, maximum flooding surfaces/sequence boundary (MFS/SB), mineralogy, isotope anomalies. Further, Moon recession changes Earth’s rotation velocity (...

This paper presents an investigation into the degree and nature of chemicalweathering during soil formation on a volcanic (phonolite) substrate on the southern slopes of Mt. Kilimanjaro in northern Tanzania. The high field strength elements Nb and Ta were used to estimate enrichments and depletions relative to the bedrock. The degree ofweatheringwas found to increasewith depth in the soil profi...

Understanding the development of grassland ecosystems is critical for understanding the evolution of their associated vertebrate faunas. We focus on the central and southern portions of the Great Plains, which is the largest continuous grassland in North America and has a well-documented mammalian fossil record. Modern biomass in this region is dominated by C4 grasses, but paleontological evide...
