Journal ArticleDOI
TL;DR: In this article, the spatial distribution and ages of Central Asian loess sediments are investigated and the authors recommend that the loess distribution should be divided into three subregions (Western CA, Northern CA, and Eastern CA), which are approximately coincident with the 60% and 30% winter-half year's precipitation percentage contours.

Journal ArticleDOI
TL;DR: The relationship between plant form and climate has been recognised for more than two millennia, and the idea that fossils can indicate climate change was first recorded almost a thousand years ago.

27 citations


Journal ArticleDOI

Journal ArticleDOI
TL;DR: In this paper, a series of paleogeographic maps, developed in response to temporally and spatially changing influences of climate, eustasy, and a continent-wide late Paleozoic orogenic system, are presented.

Journal ArticleDOI
TL;DR: In this paper, the response of the hydrologic system to greenhouse gas forcing of the magnitude estimated for the PETM (i.e., 2×) was evaluated on the Mid-Atlantic Coasts of North America (New Jersey) and Europe (Spain) focusing on the proxy records of regional precipitation.

Journal ArticleDOI
TL;DR: In this article, atmospheric rivers and related precipitation are analyzed in high-resolution climate simulations during the Eocene using a sophisticated Earth System Model framework, testing both greenhouse gas and orbital sensitivities.

Journal ArticleDOI
TL;DR: A continuously cored well covering the Carboniferous-Permian Benxi, Taiyuan, and Shanxi formations in the eastern Ordos Basin provides a rare window into environmental conditions of the marine-continental transitional strata as mentioned in this paper.

Journal ArticleDOI
TL;DR: In this paper, the authors classify the depositional environments of carbonates into five: seawater in the marine environment, estuarine water associated with the transition zone between continental and marine environments, river and lacustrine of continental waters, pore water of diagenetic environments and hydrothermal fluids.

Journal ArticleDOI
TL;DR: In this article, petrography, U-Pb dating and Hf isotopic data for detrital zircons from Upper Carboniferous-Upper Permian strata in the South Qiangtang Terrane on the Tibetan Plateau were presented.

Journal ArticleDOI
TL;DR: The authors developed a chronostratigraphic framework for three of the cores based on 40Ar/39Ar dating of core and outcrop volcanic and volcaniclastic units, core paleomagnetic stratigraphy, and tephrochemical correlation between cores and from core to outcrop.

Journal ArticleDOI
TL;DR: In this paper, the authors present new evidence of sea surface temperature (SST) estimates and δ18O of seawater from the paired data of Mg/Ca and measured from planktonic foraminifer Globigerinoides ruber (white) in core BoB-24 collected from the central Bay of Bengal (BoB), tropical Indian Ocean.

Journal ArticleDOI
TL;DR: In this article, the authors conducted an integrated investigation of field observations, U-Pb dating of igneous and detrital zircons, and a synthesis of previously published data to constrain and reconstruct the pre-Cenozoic history of the northern Qilian Shan.

Journal ArticleDOI
TL;DR: Li et al. as mentioned in this paper provided insights into the paleoenvironmental and depositional history of various shales of the Es1 Member of Paleogene Shahejie Formation, Qikou Sag, Bohai Basin, and addressed the controlling factors of organic matter (OM) accumulation and preservation in these deposits based on petrographic characteristics, organic geochemistry, and major and trace elements data.


Journal ArticleDOI
TL;DR: In this article, rare earth element (REE) and grain-size analyses were carried out on a well-dated sediment core from Lake Lugu, SW China, to establish the provenance of aeolian deposits preserved within the lake during the last 32kyr.

Journal ArticleDOI
TL;DR: In this paper, a meta-analytical approach is used to estimate the functional charcoal source area (FCSA), or the globally applicable source area necessary to facilitate spatially-explicit fire history reconstructions and data-model comparisons.

Journal ArticleDOI
TL;DR: The term keratolite as mentioned in this paper is proposed for a type of sponge carbonate dominated by vermiform fabric that preserves the outlines of the original spongin skeleton, which is called thinly thin.

Journal ArticleDOI
TL;DR: In this article, the late Oligocene-early Miocene palaeovegetation and palaeoclimate in the Ying-Qiong Basin, South China Sea were comprehensively reconstructed using higher plant-derived biomarkers, palynological records, clay minerals, and kerogen maceral compositions of shales.

Journal ArticleDOI
TL;DR: In this article, the relative abundance of C4 grasses and C3 vegetation based on the carbon isotopic composition of leaf wax biomarkers (δ13Cwax), which captures a signal of regional vegetation change was found.

Journal ArticleDOI
TL;DR: In this paper, the authors report a regional changeover from tropical/subtropical ecosystems in the Late Oligocene ecosystem to a cooler, alpine biota of the Early Miocene ecosystem in the Tibetan Plateau region.

Journal ArticleDOI
TL;DR: In this article, the formation of authigenic glauconite within a biostratigraphically constrained section encompassing the Paleocene-Eocene Thermal Maximum (PETM) was investigated.

Journal ArticleDOI
TL;DR: In this paper, the authors explore these conditions using new and previously published Fe-speciation data from seven basins distributed across five paleocontinents representing a range of depositional conditions and reveal anoxia was a common and persistent feature of deeper-water environments and that it was generally absent from shallower-waters across this timespan.

Journal ArticleDOI
TL;DR: In this paper, the abundance of C4 plants calculated from the δ13CSC and δ 13CFAME values is ~2% to 89% higher compared to the λ13CSOM and λ 13CNOM values-based estimates, which can lead to uncertainty in paleovegetational records.

Journal ArticleDOI
TL;DR: A review of advances in the field of sclerochronology, with an emphasis on mollusks, including trends in the analysis of growth patterns, development and interpretation of proxies, diversity of taxa used in SCLerochronological research, as well as the geographic and temporal coverage.

Journal ArticleDOI
TL;DR: In this paper, conodont-based δ18Ophos studies from two core sections in Estonia (Mehikoorma-421 and Valga-10) indicate that the pre-Hirnantian Late Ordovician was characterized by a general cooling trend: a rapid climate cooling in early Sandbian and a less intense cooling in the late Sandbian through Katian.

Journal ArticleDOI
