Structural evolution characteristics and hydrocarbon accumulation of Jinma-Yazihe area

Youqicang pingjia yu kaifa, 2020
Jinma-Yazihe area is located at the junction of Longmenshan fold-thrust belt and Sichuan basin. Based on the 3D seismic data, the characteristics of faults and the process of tectonic evolution are analyzed.

A Late Paleozoic Hydrothermal Gold Mineralization Event in the Northern Margin of the North China Craton: Evidence of In Situ Apatite U‐Pb Dating and Hg Isotope Tracing of the Giant Hadamengou Gold Deposit

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 5, May 2025.
Abstract The northern margin of the North China Craton (NCC) hosts large numbers of hydrothermal gold deposits, with mineralization ages ranging from the Paleozoic to Mesozoic eras. The genesis of these deposits has been primarily ascribed to magmatic‐hydrothermal or crustal‐metamorphic fluid models. The Hadamengou gold deposit (>170 t Au), the largest

High‐Resolution Lithospheric Shear Velocity Structure of the Suqian Segment of the Tanlu Fault Zone From Ambient Noise Tomography

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 5, May 2025.
Abstract To understand causes of the Suqian seismic gap and the 1668 M8.5 Tancheng earthquake, we determine a new 3‐D S‐wave velocity (Vs) model of the lithosphere under the Suqian segment of the Tanlu fault zone in eastern China using ambient noise tomography. Rayleigh wave phase velocity dispersions at periods of 5–33 s are collected from seismograms

Discovery of Middle-Late Devonian and Early Permian magmatic events in East Asia and their implication for the Indosinian orogeny in South China: Insights from the sedimentary record

, 2019
Whether the driver of the Indosinian orogeny in the South China block was related to the evolution of the Paleotethyan Ocean or the Paleo-Pacific Ocean has been a point of much debate.

Evidence of two-stage strike-slip structural deformation of Shaya Uplift, northern Tarim Basin

Shiyou shiyan dizhi, 2020
The Shaya Uplift, an important structural belt in the northern Tarim Basin, northwestern China, has been regarded as a thrust belt. However, this recognition is not only incompatible with the flower structures on the seismic profiles, but also ...

Ten Questions of East Asian Tectonics

Acta Geologica Sinica - English Edition, Volume 99, Issue 2, Page 297-319, April 2025.
Abstract East Asian continental tectonics challenges the plate tectonics paradigm with its diffuse intraplate deformation, magmatism, and earthquakes. Despite extensive studies, fundamental questions persist. This review examines ten critical questions of East Asian tectonics, including the thickness of the continental lithosphere, the origin of the ...

Table1_Formation of an Intracontinental Orogen Above the Permo-Triassic Mantle Convection Cell in the Paleo-Tethys Tectonic Realm due to Far-Field Stress Derived From Continental Margins.XLS

, 2022
The identification of intraplate orogens seemingly poses challenges to the plate tectonic theory. Delineating the formation processes of intraplate orogens can provide clues for the better understandings of the above issue.

Geophysics Indicator of Sandstone‐Type Uranium Mineralization in the Northern Ordos Basin, China: Analysis From Gravity and Magnetic Data

Earth and Space Science, Volume 12, Issue 3, March 2025.
Abstract Ordos Basin, one of the largest uranium resource areas in China, holds significant potential due to its favorable metallogenic geological conditions and promising potential. Early exploration efforts primarily targeted sandstone‐hosted uranium deposits.

Geological Knowledge‐Guided Dual‐Branch Deep Learning Model for Identification of Geochemical Anomalies Related to Mineralization

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 1, March 2025.
Abstract Geochemical survey data are a type of spatial big data that play an increasingly significant role in mineral exploration. One challenge in the era of big data is how to mine geochemical data in support of mineral exploration. In this study, based on a generative adversarial network framework, we proposed an unsupervised spatial–spectrum dual ...
