SEISMODYNAMICS AND DEEP INTERNAL ORIGIN OF THE NORTH CHINA ZONE OF STRONG EARTHQUAKES

open access: yesГеодинамика и тектонофизика, 2015
Space-and-time regularities of seismicity of the North China (Tan-Lu) zone are studies, and tectonic nature of strong earthquakes is analyzed. The concept of its genesis is still a matter of debate as this zone is located in the centre of the ancient ...

Measured and calculated seismic velocities and densities for granulites from xenolith occurrences and adjacent exposed lower crustal sections: A comparative study from the North China craton [PDF]

open access: yes, 2000
Granulites from the Neogene xenolith-bearing Hannuoba alkaline basalt and from the Manjinggou-Wayaokou exposed lower crustal section in the Archean Huai'an terrain, which occurs within and surrounds the Hannuoba basalt, provide a unique opportunity for a

EARLY PRECAMBRIAN CRUSTAL EVOLUTION OF THE BELOMORIAN AND TRANS-NORTH CHINA OROGENS AND SUPERCONTINENTS RECONSTRUCTION

open access: yesГеодинамика и тектонофизика, 2017
Comparative analysis of the crustal evolution of the Early Precambrian Belomorian and Trans-North China orogens (Fig. 1) has shown [Slabunov et al., 2015] that: Both belts were formed by the superposition of two Precambrian orogenies.

Geochemical characteristics of apatite in metabasic rocks under different metamorphic conditions: a case study from the Paleoproterozoic Trans-North China Orogen

open access: yesDizhi lixue xuebao
Objective  Apatite is a common accessory mineral that is widely distributed in various rock types. Its U-Pb age, trace elements (particularly REE, Th, U, and Sr), and Sr-Nd isotopic compositions provide important information on its chronology and ...

Origin and Evolution of the Ore-Forming Fluids in the Liyuan Gold Deposit, Central North China Craton: Constraints from Fluid Inclusions and H-O-C Isotopic Compositions

open access: yesGeofluids, 2017
The Liyuan gold deposit is hosted within Archean basement metamorphic rocks and controlled by the NNE-trending faults in the central North China Craton. The ore-forming processes can be divided into three stages (early, middle, and late).
