Lithosphere Mantle Density of the North China Craton [PDF]

open access: yesJournal of Geophysical Research: Solid Earth, 2020
AbstractWe constrain the lithospheric mantle density of the North China Craton (NCC) at both in situ and standard temperature‐pressure (STP) conditions from gravity data. The lithosphere‐asthenosphere boundary (LAB) depth is constrained by our new thermal model, which is based on a new regional heat flow data set and a recent regional crustal model ...

Late paleozoic to early mesozoic provenance record of paleo-pacific subduction beneath South China [PDF]

open access: yes, 2015

Paleoproterozoic Plate Tectonics Recorded in the Northern Margin Orogen, North China Craton

open access: yesGeochemistry, Geophysics, Geosystems, 2022
The occurrence of plate tectonic processes on Earth during the Paleoproterozoic is supported by ca. 2.2–1.8 Ga subduction‐collision orogens associated with the assembly of the Columbia‐Nuna supercontinent. Subsequent supercontinent breakup is evidence by

Geochemistry and detrital zircon geochronology of Khammam Schist Belt, Eastern Dharwar Craton: Implication for India – North China Craton –Antarctica connection in Paleo-Mesoproterozoic crustal assembly

open access: yesGeosystems and Geoenvironment, 2023
This communication reports the results of geochemical investigations and detrital zircon geochronology of metasediments of the Khammam Schist Belt that occur at the trijunction of the Eastern Dharwar Craton–Bastar Craton–Eastern Ghats Belt. Biotite (XMg =

Metamorphic petrology and geology in China: A review

open access: yesChina Geology, 2018
: The development of metamorphic petrology to metamorphic geology in China has a long history. Ancient basement metamorphic rocks are distributed primarily in the North China Craton, the Yangtze Block and Tarim Craton. They are mainly made up of plutonic

On and Off the North China Craton: Where is the Archaean Keel? [PDF]

open access: yesJournal 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 access: yesOpen 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.

Provenance and tectonic implications of the Yanshi bauxite area in Western Henan, China [PDF]

open access: yesE3S 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.

A discovery of extremely REE-rich kimberlites: A possible new type of REE-deposit

open access: yesSolid 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 ...
