Geochemical characteristics of surface dune sand in the Mu Us Desert, Inner Mongolia, and implications for reconstructing the paleoenvironment [PDF]
, 2018 We present a new dataset from 28 active and 13 stabilizedesemi stabilized dunefields in the Mu Us Desert to report the geochemical macroscale properties as well as reveal the relationship between various chemical ratios and modern climate conditions ...

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract Topographic highlands commonly develop along convergent plate boundaries through long‐term processes such as subduction and continental collision. However, the pre‐Cenozoic mountain‐building history of deep‐time orogenic systems in northeastern Pangaea remains poorly constrained due to later tectonic overprinting and denudation.

鄂尔多斯盆地姬塬地区长6 储层矿物含量与孔隙度的线性关系 [PDF]
, 2019 矿物含量是影响储层物性的重要因素之一。为了较全面地分析不同类型矿物含量对储层孔隙度的影响，以鄂尔多斯盆地姬塬地区长6 砂岩储层为例，探索性地运用多元逐步线性回归法分析了石英含量（x1）、长石含量（x2）、岩屑含量（x3）、绿泥石含量（x4）、伊利石含量（x5）、高岭石含量（x6）、硅质含量（x7）以及铁方解石含量（x8）与孔隙度（y）的关系，建立了矿物含量（xi）与孔隙度（y）之间的回归模型：y = 21.131-0.086 x2-0.113 x3-0.554 x4-0.370 x5-0.199 x6 ...

LA-ICP-MS U-Pb geochronology of detrital zircons from the Jining Complex, North China Craton and its tectonic significance [PDF]
, 2006 LA-ICP-MS U-Pb zircon dating and cathodoluminescene (CL) image analysis were carried out to determine the protolith and metamorphic ages of high-grade Al-rich gneisses, named as "khondalites", from the Jining Complex of the North China Craton (NCC).

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract The Curie point depth (CPD), a key indicator of the lithosphere's thermal structure, is typically estimated using spectral analysis or interface inversion methods. However, these approaches often neglect the effects of remanent magnetization, leading to substantial uncertainty.

Post-critical SsPmp and its applications to Virtual Deep Seismic Sounding (VDSS)—1: sensitivity to lithospheric 1-D and 2-D structure [PDF]
, 2018 Virtual Deep Seismic Sounding (VDSS) has recently emerged as a novel method to image the Moho and potentially other lithospheric boundaries. The behaviour of SsPmp, the post-critical reflection phase at the Moho that is utilized in VDSS, is rich with ...

Palaeostructure, evolution and tight oil distribution of the Ordos Basin, China
Oil & Gas Science and Technology, 2019 Whether or not the tight oil in the Triassic Yanchang Formation of the Ordos Basin is controlled by structural factors is a controversial issue, the relationship between the structural factors of the strata and the distribution of tight oil is limited to

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.Abstract Widespread mafic magmatism at ca. 1.8–1.7 Ga across fragments of the Columbia supercontinent records a transition in the Earth's supercontinent cycle. The paleogeographic position of the Dunhuang Block in northwestern China within Columbia, and its role in this tectonic reorganization, remain controversial.
