The evolution of the lunar magnetic field can reveal Moon’s interior structure, thermal history, and surface environment. mid-to-late-stage is poorly constrained, thus, existence a long-lived dynamo remains controversial. Chang’e-5 mission returned heretofore youngest mare basalts from Oceanus Procellarum uniquely positioned at midlatitude. We recovered weak paleointensities ~2 to 4 microtesla basalt clasts 2 billion years ago, attesting longevity until least midstage. This paleomagnetic...
The India-Asia collision is an outstanding smoking gun in the study of continental dynamics. How and when occurred remains a long-standing controversy. Here we present two new paleomagnetic data sets from rocks deposited on distal part Indian passive margin, which indicate that Tethyan Himalaya terrane was situated at paleolatitude ∼19.4°S ∼75 Ma moved rapidly northward to reach ∼13.7°N ∼61 Ma. This implies rifted India after Ma, generating North Sea. We document two-stage collision, first...
The enigmatic geodynamic processes involved in the India-Asia collision shape our understanding of uplift and deformation Tibetan Plateau subsequent changes land-sea distribution pattern, monsoon-arid environments biotic evolution Central-Eastern Asia. However, current models dealing with history exhibit significant discrepancies how, when where exactly India Asia occurred. Recently, we proposed a new hypothesis that favored opening closure North Sea during late Cretaceous to Paleogene. Here...
Ordered mesoporous carbons composed of arrays nanotubes have been synthesized using ordered silica templates via catalytic chemical vapor deposition. The possess bimodal pores, namely, the pores arise from "replica" frameworks template and correspond to carbon formed in channels (see Figure).
Abstract The Tibetan Plateau accommodated major upper crustal shortening during Indian Plate oceanic and continental lithosphere subduction. Deciphering whether was continuous or episodic, how it correlates to geodynamic changes is challenging. Here we apply anisotropy of magnetic susceptibility (AMS), a sensitive synsedimentary strain indicator, ~3 km thick magnetostratigraphically dated sedimentary section (69–41.5 Ma) in eastern Tibet. AMS shows “earliest deformation” fabrics from 69–52...
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 The absence of reliable paleomagnetic constraints from the Lhasa Block has led to alternative interpretations its late Paleozoic position and timing rifting Gondwana, reflecting uncertainties in early Neo‐Tethyan paleogeography. This study presents geochronological data middle Permian Luobadui Formation, providing a new paleogeographic constraint on Block. Despite possible remagnetization, dual‐polarity magnetization, hosted different minerals lithologies, likely represents...
Abstract The Clarion and Clipperton Fracture Zones in the Eastern Pacific are well known as a manganese nodule belt, which developed since late Oligocene. slow growth rate of these marine ferromanganese nodules implies that they have potentially recorded long‐term environmental changes. To produce records from nodules, their chronology needs to be established first. In order achieve this objective, many dating methods been applied; however, due relatively low‐resolution temporal constraint,...
The Lower Cretaceous Dalazi Formation in the Yanji Basin, eastern Jilin Province is of particular interest because it contains key fresh water fossil taxa, oil and gas resources, a potential terrestrial Albian–Cenomanian boundary, regional unconformities. However, lack precise chronology for non-marine strata has precluded better understanding stratigraphic correlation processes. Here, we report magnetostratigraphic U–Pb geochronologic results sedimentary sequence from Xing’antun section...
Standard-size samples are usually used for traditional paleomagnetic studies. In some cases, small irregular employed considering their amount and magnetic strength as well experiment efficiency. With the development of deep space exploration, demand studying weak is increasing. this study, we established a measurement technique rare samples. We designed low-background, sample-nondestructive high-flexibility holders with various materials different measurements customized holders, estimated...
Although epitaxial growth of Si films on both surfaces silicon wafer (epi-Si/Si-wafer/epi-Si) can be realized in foundry by means mounting certain amounts wafers a boat commercial specialized chemical vapor deposition equipment (s-CVD), for its counterpart epi-SiC/Si-wafer/epi-SiC, neither is it readily s-CVD, nor easily achieved conventional (c-CVD) which generally used 3C-SiC single surface (epi-SiC/Si-wafer). Since the epi-SiC/Si-wafer/epi-SiC one run more efficient, and anticipated, this...
Seamounts are ubiquitous topographic units in the global oceans, and Caiwei Guyot Magellan of western Pacific is a prime example. In this study, we analyzed well-dated sediment core using magnetic properties, grain size, metal enrichment to uncover regional ventilation history during middle Pleistocene explore potential linkages climate changes. Our principal findings as follows: (1) The median size 3.3 ± 0.2 μm, clay silt particles exhibit minimal variation, with average values 52.8 1.8%...
Understanding sediment dynamics and their controlling factors is essential for Quaternary studies, yet they remain poorly documented in the Mariana Trench. In this work, we examine basic character from a core collected at depth of 6470 m southern part Trench, documenting changes sedimentary over past ~440 kyr. Our primary findings are as follows: (1) The median grain size 13.6 ± 12.0 μm, minimal clay (30.9 9.4%) silt (56.6 4.0%) contents, indicating low-dynamic depositional environment; (2)...
