Tibetan Plateau uplift has been suggested as the main driving force for mid-latitude Asian inland aridity (AIA) and deposition of thick aeolian sequences in northern China since Miocene. However, relationship between earlier AIA mountain building is uncertain because a lack corresponding with accurate age constraints. We here present results continuous sequence that spans interval from >51 to 39 Ma eastern Xorkol Basin, Altun Shan, northeastern Plateau. The basal studied postdates initial by...
The middle Cambrian was a critical period of Earth’s history, marked by explosive diversification metazoans and several profound changes in surface environments global climate. A valid temporal framework for the across major bio-events is yet poorly constrained, millennial-scale climate variability (MCV) are not fully addressed. Here, high-resolution spectral gamma-ray logs, Potassium, Uranium, Thorium magnetic susceptibility records utilized to conduct cyclostratigraphic analysis...
Abstract As one of the most widespread components in marine sediments, calcium carbonate (CaCO 3 ) plays a crucial role global carbon cycle and climate changes. To efficiently semi‐quantify CaCO concentration, more effective, non‐destructive, economic, accurate technique is required. Diffuse reflectance spectroscopy (DRS) has been widely used for detection quantification minerals but less studied . This study synthesized series samples with well‐determined content to analyze visible...
Hematite concentration is an important climatic proxy for environmental (climatic) studies of soils and sediments. However, the accurate quantification naturally occurring hematite has always been a difficult question, especially those areas with lower concentrations. Diffuse reflectance spectroscopy (DRS) effective method identification detection limits. In this study, we synthesized set samples well-determined concentrations to explore exact detectable range propose most transfer function...
Abstract The Philippine Sea Plate (PSP) and the South China (SCS), located at intersection of Eurasian, Pacific, Indo‐Australian plates, are key areas for global plate reconstruction. However, relationships between PSP SCS still elusive. Here we report a new paleolatitude determination (16.0° ± 4.5°N ∼20 Ma) from Ocean Drilling Program Site 1177 in Shikoku Basin (SB) within eastern PSP. results indicate that SB had geographical affinity with early Miocene. Furthermore, similarity U‐Pb zircon...
High- and low-latitude climatic processes in the North Pacific Ocean are important components of global climate system. For example, interplay among atmospheric circulation, ocean biological productivity affects carbon dioxide levels marine oxygen concentrations. Here we review recent research on paleoclimatic paleoceanographic evolution during late Quaternary its response to external forcings such as orbital insolation, ice-sheet extent, greenhouse gas First, summarize principles...
Abstract North Pacific Ocean sediments are important archives of geomagnetic field and paleoenvironmental evolutions, yet late Quaternary sedimentary sequences in the less explored because generally low sedimentation rates challenge dating deposited below calcite compensation depth. Core NP02 from contain three visible tephra layers, which identified as To‐Of, Spfa‐1, Kt‐3 tephra, respectively. An age model for core is established based on correlation one radiocarbon date, gives a mean rate...
Abstract The mid-latitude westerly winds are a major component of the global atmospheric circulation and dominant factor in climate change. Understanding their behaviour controls on variations under different background states is essential for assessing system feedback. Here we present midlatitude North Pacific Ocean aeolian dust record from core NP02 through last glacial cycle, during which extreme abrupt climatic oscillations occurred. We find low contents Heinrich stadials 2, 4, 5, 5a...
Abstract The relationships among the abundance of magnetofossils, ensuing magnetic properties, and controlling paleoenvironmental factors in marine sediments remain broadly unexplored. Here, we identify magnetofossils core XB1 from northwestern South China Sea (SCS) since end Last Glacial. Using rock electron microscopic data, propose a model that links anisotropy susceptibility fabric magnetofossils. magnetofossil concentration increases significantly during 14.7–4.7 ka period, which turns...
Abstract The observed variations in intense geomagnetic flux lobes have a significant impact on regional fields, and produce unique characteristics. To investigate the time‐dependent effect of Siberian lobe field East Asia, we reconstructed stacked full‐vector paleomagnetic secular variation record (since 2000 BCE) from three sediment cores collected Bohai Sea, China. Age models studied were established through combination radiocarbon 14 C dating inter‐profile correlation mass‐normalized...
The kinematic reconstruction of the Philippine Sea Plate (PSP) holds significant importance in elucidating Australia−SE Asia collision and Pacific subduction. Previous studies suggested an overall northward motion PSP since its inception, but this first-order model cannot account for observed inconsistencies drift distances among certain sites. Here, we conducted high-resolution Oligocene magnetostratigraphic paleomagnetic research from Deep Drilling Project (DSDP) Site 445, showing that...

The biological pump and deep-ocean ventilation in eastern equatorial Pacific (EEP) Ocean are thought to play a crucial role cases of global CO2 change. However, the integral these two processes regulating atmospheric perturbations over major climate transitions still unknown. Here, we present magnetofossil record EEP sediments from Sites 1333 1218 across Eocene-Oligocene Transition (EOT) when ice-sheet was first established on Antarctica. We find that dust fertilization bottom-water...
The Ocean Drilling Program Site 1177 recovered the oldest (∼23 Ma) sedimentary records in Shikoku Basin, northeastern part of Philippine Sea Plate. Changes sediment provenances bear important implications for tectonic evolution Plate, but existing data are still controversial early Miocene. By integrating Sr-Nd isotopes, rock-magnetic parameters, diffuse reflectance spectroscopy, and previous on detrital zircons clay minerals from 1177, we found that a significant provenance shift occurred...
