Thinning and destruction of the cratonic lithosphere: A global perspective
Science China Earth Sciences, 2014It has been proposed that the North China Craton (NCC) was thinned up to a thickness of >100 km during the Phanerozoic, and underwent an associated craton destruction. Evidently, it is an important topic worthy of future study to understanding the mechanism of cratonic destruction and its role played in the continental evolution.

Detailed knowledge of lithospheric structure is essential for understanding the long-term evolution and dynamics of continents. We present an image of lithospheric structure across the central and western North China Craton (NCC), derived using S and P receiver functions from a dense seismic array. A negative velocity discontinuity is identified at ∼80–

Craton Destruction 2: Evolution of Cratonic Lithosphere After a Rapid Keel Delamination Event
Journal of Geophysical Research: Solid Earth, 2018AbstractCratonic lithosphere beneath the eastern North China Craton has undergone extensive destruction since early Jurassic times (approximately 190 Ma). This is recorded in its episodic tectonic and magmatic history. In this time, its lithosphere changed thickness from approximately 200 km to <60 km.

Numerical modeling of north china craton Thinning and destruction.
2023 The North China Craton is located on the Eurasian continental margin. Since the Mesozoic, the Izanagi and Pacific plates are subducting westward with the trench retreating eastward over time. This process is accompanied by extensive magmatism, development of rift basins, and the formation of the Japan sea.

Destruction of the Wyoming craton: Seismic evidence and geodynamic processes
Geology, 2016Abstract Cratons are old and strong continental cores where the lithosphere is thick and remains largely undeformed for 2–3 b.y. Unlike typical cratons, the Wyoming craton underwent pervasive deformation ca. 80–55 Ma during the Laramide orogeny in the west-central United States, and has been subsequently encroached upon by the ...

Destruction of the North China Craton Induced by Ridge Subductions
The Journal of Geology, 2013AbstractThe destruction of the North China Craton (NCC) mainly occurred in the Cretaceous and has been attributed to a “top-down” rapid delamination, “bottom-up” long-term thermal/chemical erosions, or hydration by subduction-released fluids. On the basis of the distribution of one Jurassic and two Early Cretaceous adakite belts and the drifting ...

Experimental constraints on the destruction mechanism of the North China Craton
Lithos, 2012Abstract Craton destruction is a complex process involving both chemical and physical interactions between the crust and the mantle. Several mechanisms, including thermo-chemical erosion, delamination, lithosphere extension and subducting slab dehydration, have been proposed to explain the destruction of the North China Craton (NCC).

AbstractThe North China Craton (NCC) is believed to be the best example of cratonic destruction. However, the processes leading to cratonic destruction remain unclear, largely due to a lack of knowledge of the nature of the Mesozoic NCC lithospheric mantle.

We picked new traveltime residual datasets in three frequency bands (0.02–0.1, 0.1–0.8, and 0.8–2.0 Hz) for P-waves from 793 teleseismic events and two frequency bands (0.02–0.1 and 0.1–0.8 Hz) for S-waves from 310 teleseismic events, recorded by 389 permanent stations of the China National Seismic Network and 832 broadband stations of 10 temporary

Abstract A comprehensive synthesis of U–Pb geochronology and Hf isotopes of zircons from granulite/pyroxenite xenoliths entrained in Phanerozoic magmatic rocks and inherited xenocrysts from the associated lower crust rocks from various domains of the North China Craton (NCC) provides new insights into understanding the Phanerozoic evolution of the ...
