Crustal thickness of the Jiaodong Peninsula in the Mesozoic: Implications for the destruction of the North China Craton

open access: yesFrontiers in Earth Science, 2023
The North China Craton underwent extensive and widespread crustal reworking (or decratonization) during the Mesozoic. However, how the decratonization operated is not well understood.

Regional characteristics of the lithospheric structure in the southeast of North China revealed by explosion seismology

open access: yesGeodesy and Geodynamics, 2021
Based on the blasting seismic detection data obtained in the southeast of North China in recent years, this paper comprehensively analyzes and studies the crust-mantle lithospheric structure and seismological characteristics of different tectonic regions,

A seismic model for crustal structure in North China Craton

open access: yesEarth and Planetary Physics, 2017
We present a digital crustal model in North China Craton (NCC). The construction of crustal model is based on digitization of original seismic sounding profiles, and new results of three-dimensional structure images of receiver functions.

Depth migration of crustal-scale seismic reflection profiles: A case study in the Bohai Bay basin

open access: yesFrontiers in Earth Science, 2023
The application of the pre-stack depth migration (PSDM) method using deep seismic reflection data is still a challenge. In this paper, a deep seismic reflection dataset collected from the Bohai Bay Basin is used to test the applicability of the pre-stack

Construction and destruction of some North American cratons [PDF]

open access: yesTectonophysics, 2017
Abstract Construction histories of Archean cratons remain poorly understood; their destruction is even less clear because of its rarity, but metasomatic weakening is an essential precursor. By assembling geophysical and geochemical data in 3-D lithosphere models, a clearer understanding of the geometry of major structures within the Rae, Slave and ...

The Crustal Anisotropy of West Ordos Block and Its Geodynamic Implications

open access: yesGeochemistry, Geophysics, Geosystems, 2021
Based on the teleseismic records of the dense broadband seismic array, the crustal anisotropy parameters of the west Ordos block and its adjacent regions were determined with P wave receiver functions.

Gold mineralization and metallogenesis associated with mantle dynamics in East China

open access: yesFrontiers in Earth Science, 2022
East China can be divided into two parts: the North China Block (or North China Craton) (NCC) and the South China Block (SCB). The mechanism for the destruction of the NCC and the large-scale magmatic activity in the SCB during the Mesozoic is a major ...

Mesozoic Tectono-Thermal Event of the Qinshui Basin, Central North China Craton: Insights From Illite Crystallinity and Vitrinite Reflectance

open access: yesFrontiers in Earth Science, 2021
The Qinshui Basin is in the Central Orogenic Belt of the North China Craton (NCC), and the production of coalbed methane accounts for 70% of China’s total coalbed methane output.

Crustal structure beneath the central and western North China from receiver function analysis

open access: yesEarthquake Science, 2022
The North China Craton (NCC) is one of the oldest cratons on earth. Several important tectonic transformations of Mesozoic-Cenozoic tectonic regime led to the destruction of the North China craton. The knowledge of crustal structure can provide important

Modeling Craton Destruction by Hydration‐Induced Weakening of the Upper Mantle [PDF]

open access: yesJournal of Geophysical Research: Solid Earth, 2017
AbstractGrowing evidence shows that lithospheric mantle beneath cratons may contain a certain amount of water that originated from dehydration of subducted slabs or mantle metasomatism. As water can significantly reduce the viscosity of nominally anhydrous minerals such as olivine, hydration‐induced rheological weakening is a possible mechanism for the
