On and Off the North China Craton: Where is the Archaean Keel? [PDF]
Journal of Petrology, 2000 Geophysical data indicate that the lithosphere beneath the North China Craton (NCC) is similar to 80 km thick with high heat flow within the craton. This is somewhat in disagreement with the presence of Archaean crustal rocks and kimberlite-hosted xenoliths that point to the existence of garnet-diamond-facies mantle beneath the craton, as recently as ...

Provenance analysis of the Late Triassic Yichuan Basin: constraints from zircon U-Pb geochronology
Open Geosciences, 2018 Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) U-Pb dating has been performed on detrital zircons from the Chunshuyao Formation sandstone of Yichuan Basin.

Paleoproterozoic–Paleozoic tectonic evolution of the Longshou Shan, western North China craton
Geosphere, 2022 The Longshou Shan of western China is the northern backstop of the Cenozoic Himalayan-Tibetan orogen and occupies a key linkage between the Tarim continent and North China craton which separate the pre-Cenozoic Tethyan orogenic system and Central Asian ...

A discovery of extremely REE-rich kimberlites: A possible new type of REE-deposit
Solid Earth Sciences, 2021 Two newly discovered Mesozoic Group II kimberlites in the southeastern margin of North China Craton show extremely high ΣREE contents (ranging from 1046 to 1869 ppm), which also higher than the nearby Weishan carbonatite and other REE-bearing rocks in ...

Provenance and tectonic implications of the Yanshi bauxite area in Western Henan, China [PDF]
E3S Web of Conferences, 2021 The bauxite layer in Western Henan supplies a large number of bauxite ores and is useful for studying tectonic movement. In this paper, the bauxite samples were selected to carry out LA-ICP-MS detrital zircons U-Pb dating and Hf isotope testing.

, 2010 An evaluation of recent S-wave receiver functions, S-wave velocities and two versions of P-wave tomographic images along various transects in the North China Craton provides some clues on the subduction-collision history of the different crustal blocks ...

Frontiers in Earth Science, 2023 Lower crust-derived granitic rocks provide constraints on the crustal reworking process and consequently give hints on the destruction mechanism of the cratons. The North China Craton (NCC) underwent extensive crustal melting in the Mesozoic.

GSA Bulletin, 2021 The debate on the role of vertical versus horizontal tectonism in Archean cratons is intimately linked to the initiation of plate tectonics. The dome-and-keel architecture has been considered as a consequence of vertical tectonism.

Study on the basement structure in the southeastern North China by blasting seismic
Geodesy and Geodynamics, 2018 Since the Mesozoic, southeastern North China Craton has experienced intense crustal thinning and lithosphere destruction. Some of the responses of the deep activity in the upper crust crystalline basement have been retained in a series of tectonic ...

, 2020 The North China Craton (NCC) hosts some of the world-class gold deposits that formed more than 2 billion years after the major orogenic cycles and cratonization. The diverse models for the genesis of these deposits remain equivocal, and mostly focused on
