Late Precambrian aulacogens of the North China craton [PDF]

open access: yes, 1985
According to tectonic styles, the Precambrian evolution history of the North China craton may be subdivided into four stages: (1) Archean consolidation in 3.5 to 2.5 Ga, (2) Early Proterozoic rifting in 2.5 to 1.8 Ga, (3) Late Precambrian aulacogen in 1 ...

Paleogeographic reconstruction of the North China Craton in the supercontinent Nuna/Columbia: paleomagnetic and geological constraints [PDF]

open access: yes, 2019
The North China Craton has abundant Precambrian geological records, but its positions in the two supercontinents are still controversial. Detailed geochronological, geochemical, rock magnetic and paleomagnetic analyses have been carried out.

A seismic model for crustal structure in North China Craton

open access: yesEarth and Planetary Physics, 2017
We present a digital crustal model in North China Craton (NCC). The construction of crustal model is based on digitization of original seismic sounding profiles, and new results of three-dimensional structure images of receiver functions.

Experimental Evaluation and Optimisation of Sealed‐Tube Combustion Methods for Silicate Nitrogen Extraction

open access: yesRapid Communications in Mass Spectrometry, Volume 41, Issue 1, 15 January 2027.
ABSTRACT Rationale Nitrogen (N) abundance and isotopic compositions in silicate rocks are commonly measured by sealed‐tube continuous‐flow isotope ratio mass spectrometry (CF‐IRMS), but combustion protocols vary widely. It remains uncertain how the quality of data obtained from different published methods compares for differing sample types. Methods To

Large‐Scale Coherent Southward Displacement of the Indochina Block: Constraints From New Late Cretaceous Paleomagnetic Studies

open access: yesGeophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract To better constrain the post‐collisional southward displacement of the Indochina Block (ICB) and the crustal deformation of the southeastern Tibetan Plateau, we present a reliable paleomagnetic study of Upper Cretaceous Nanxin Formation redbeds exposed in the Lanping area, at the northern edge of the Lanping‐Simao Terrane (LST).

Genesis of the Xiaotazigou gold deposit in the northern margin of the north China craton: constraints from sulfur isotopes, rare earth elements, and trace elements

open access: yesFrontiers in Earth Science
The Xiaotazigou gold deposit is located in the eastern section of the Chifeng–Chaoyang gold metallogenic belt on the northern margin of the North China Craton. In this study, rare earth and trace element compositions of ores and host rocks, together with

Precambrian evolution of the North China Craton

open access: yes, 2013
The North China Craton is one of the oldest cratonic blocks in the world, containing rocks as old as 3.85 billion years. Focusing on Neoarchean mantle plumes and Paleoproterozoic plate tectonics, this book combines the results from modern geological ...
