Abstract The “Day” diagram (Day et al., 1977, https://doi.org/10.1016/0031-9201(77)90108-X ) is used widely to make inferences about the domain state of magnetic mineral assemblages. Based on theoretical and empirical arguments, Day demarcated into stable “single domain” (SD), “pseudo single (“PSD”), “multidomain” (MD) zones. It straightforward necessary measurements for a sample plot results within “domain state” framework based boundaries defined by al. (1977, ). We discuss 10 issues that...
Abstract Sediments from the continental shelf are sensitive to sea level, climatic changes, and local tectonic history. In this study, we carried out a high‐resolution magnetostratigraphic investigation on longest core (NHH01, 125.64 m) recovered South Yellow Sea (SYS). An abnormal interval dominated by negative inclinations was discovered applying alternating field demagnetization (AFD) samples greigite‐bearing layer (44.90–51.80 m). contrast, of most changed positive when heated ~360°C....
Magmatism has occurred throughout Earth's history. From the early Earth to modern plate-tectonic Earth, amount of magmatism varied, but it always on multiple scales, in various tectonic environments and at depths crust mantle. Magma compositions also vary. In this paper, we argue that mechanism magma emplacement generally been passive all stages evolution. We conclude most related subduction, rifting, mid-oceanic spreading, flood basalts large igneous provinces mantle upwellings,...
Abstract Insight into the evolution of Philippine Sea‐South China Sea (SCS) plate motions helps reveal driving mechanisms long‐term tectonic complexity in Southeast Asia. Here, based on integration most recent geological and seismic data, we present a new reconstruction model for this region characterized by back‐arc extension subduction since Eocene. We suggest that western boundary Plate was constant sinistral strike‐slip fault at 55–22 Ma with clockwise self‐rotation. The connection...
Abstract Oceanic red beds, preserving primary depositional remanent magnetization, play a key role in reconstructing the Tethyan paleogeography. However, partial remagnetization caused by chemical processes could be pervasive these rocks, leading to flawed reconstructions, and thus, differentiating secondary remanences is important. In this paper, we conduct multiple X‐ray diffraction, petrographic, diffuse reflectance spectroscopy, rock magnetic analyses on Upper Cretaceous oceanic beds...
Abstract Serpentinization, a consequence of water‐rock interaction in mafic and ultramafic rocks, refers to the hydrothermal alteration olivine pyroxene with serpentine as typical product. Magnetite is produced variable amounts during this serpentinization process. Here, we conducted systematic rock magnetic study on serpentinite Ocean Drilling Program (ODP) Hole 1070A from Iberia Abyssal Plain. From bottom top, three units are distinguished rock‐magnetically: (a) serpentinized peridotite...
The modern pattern of the Asian monsoon is thought to have formed around Oligocene/Miocene transition and generally attributed Himalaya–Tibetan Plateau (H–TP) uplift. However, timing ancient over TP its response astronomical forcing uplift remains poorly known because paucity well-dated high-resolution geological records from interior. Here, we present a precession-scale cyclostratigraphic sedimentary section 27.32 23.24 million years ago (Ma) during late Oligocene epoch Nima Basin show that...
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...
Similar to loess-paleosol sequences in northwestern China, terrestrial sedimentary (red soils) southern China also provide sensitive Quaternary records of subtropical/tropical paleoclimate and paleoenvironment. Compared with red clay originated from eolian dust, soils derived bedrock have received little attention. In this study, a long core soil weathered basalt northern Hainan Island, was systematically investigated by using detailed magnetic measurements rare earth element analyses. The...

Abstract The production, transport, and deposition of mineral dust exert major influences on climate change Earth’s biogeochemical cycles. Furthermore, their imprint, as recorded in pelagic sediments, provides an avenue for determining past changes terrestrial aridity atmospheric circulation patterns response to global change. Here, by examining geochemical magnetic data obtained from a ferromanganese crust the western Pacific Ocean, we investigate eolian source-region conditions transport...
The magnetic susceptibility (χ) carried by pedogenic fine-grained ferrimagnets has been widely used as paleoclimatic proxy to elucidate long-term variations for wind-blown terrestrial loess/paleosol sequences. However, the properties of lithogenic parent material can mask signals. In this study, we systematically investigated origin superparamagnetism two modern soils from northeastern humid Pampean region, Argentina, developed on loess materials different mineralogical composition. samples...
Polarity reversals of the geomagnetic field have occurred through billions years Earth history and were first revealed in early 20th century. Almost a century later, details transitional behavior during excursions remain poorly known. Here, we present multidecadally resolved excursion record from radioisotopically dated Chinese stalagmite at 107-91 thousand before with age precision several decades. The duration directional oscillations ranged centuries 106-103 to millennia 98-92 present,...
Abstract Thermal demagnetization furnaces are widely used paleomagnetic facilities for progressive removal of naturally acquired magnetic remanence or the imparting well-controlled laboratory magnetization. An ideal thermal demagnetizer should maintain “zero” field in sample chamber during treatments. However, noises, including residual fields construction material and induced caused by alternating current (AC) heating element always present, which can contaminate results at elevated...
Mesoporous silica (m-SiO2) coated gadolinium (Gd) ions-doped upconversion nanoparticles (UCNPs) are regarded as one of most attractive nano-platforms which hold great potential in future cancer theranostics. The current general synthetic strategy for such promising structures includes the extraction surfactant molecules final step. Here, this article, we focus our interest on probing influence hydrochloric acid lanthanide ions leakage, MR sensitivity over-estimation and optical intensity...
The rapid and strong release of CO 2 caused by precipitation (known as the pulse effect) is a common phenomenon that significantly affects ecosystem C cycling. However, degree to which effect occurs overlarge regional scales remains unclear. In this study, we conducted continuous high-frequency measurements soil rates ( R s ) for 48 h after simulated precipitation, along gradient different grassland types (i.e., meadow, typical, desert) in Inner Mongolia, China. Pulse effects were assessed...
