The North China Craton is a continental crustal block with one of Earth's most complete and complex records of igneous, sedimentary and metamorphic processes. [1] It is located in northeast China, Inner Mongolia, the Yellow Sea, and North Korea. [1] The term craton designates this as a piece of continent that is stable, buoyant and rigid.

2020年8月28日 · We 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 ...

2009年10月30日 · The present paper expounds the lithospheric structure of North China Craton, displays the features of individual sub-regions of NCC and neighboring tectonic units (Fig. 1), and discusses their implications for the contemporary tectonics and past evolution.

2022年7月18日 · Our results suggest a transition from the Pacific subduction dominating tectonic regime to the India-Asia collision dominating lithospheric deformation framework in the Cenozoic and ongoing lithospheric alteration of the NCC. The NCC is one of the oldest cratons in China and a typical example of cratonic reactivation.

2013年4月15日 · We chose 1320°C as the typical LAB temperature in the North China Craton. The derived LAB depth in Huabei Basin was similar with the receiver function results [Chen, 2010]. The derived average depth of LAB in our study region is 86 km.

2016年6月1日 · Moho depth, LAB depth and average crustal density in the North China Craton are obtained. Lithosphere thinning features are discussed and compared with thermal and seismic results. The lithospheric structure of ancient cratons provides important constraints on models relating to tectonic evolution and mantle dynamics.

2019年7月25日 · There is an apparent deepening of the LAB to ∼120 km beneath the South North China Basin in the eastern NCC, whereas the LAB beneath the Yangtze Craton and Cathasia Block is flat and generally no deeper than 100 km.

2023年6月1日 · Results show that the lithospheric thickness is ∼90–100 km, thinner than the current estimated by seismic observations (90–130 km). This variation indicates that the central NCC's lithosphere underwent Mesozoic thinning and Cenozoic accretion.

2023年12月29日 · We present high-resolution 3-D images of isotropic P -wave velocity (Vp), azimuthal anisotropy (AAN) and radial anisotropy (RAN) down to 700 km depth beneath the North China Craton (NCC) and adjacent areas, which are obtained by inverting a great number of high-quality arrival time data recorded at 1374 portable seismic stations and 635 permanen...

2020年11月10日 · Here we provide an integrated constraint on the lithospheric mantle structure of the NCC by comprehensive semiology, gravity and thermal studies with xenolith data involving depth (levels in the lithosphere), property (chemical and physical), and timing (formation and reworking ages).
