TL;DR: The crustal growth and stabilization of the North China Craton (NCC) relate to three major geological events in the Precambrian: (1) a major phase of continental growth at ca. 2.9-2.7 Ga, (2) the amalgamation of micro-blocks and cratonization at 2.5-3.5 Ga, and (3) Paleoproterozoic rifting-subduction-accretion-collision tectonics and subsequent high-grade granulite facies metamorphism-granitoid mag

TL;DR: A supercontinent, here named Columbia, may have contained nearly all of the earth's continental blocks at some time between 1.9 Ga and 1.5 Ga.

TL;DR: In this paper, the authors proposed a double-sided subduction history for the North China Craton (NCC) similar to the ongoing subduction process in the Western Pacific, which is considered to promote rapid amalgamation of continental fragments within supercontinents and the subduction polarities and mantle dynamics are therefore considered to be critical in evaluating the final assembly of the Paleoproterozoic supercontinent Columbia.

TL;DR: The Qinling Orogenic Belt (QOB) as mentioned in this paper is a composite orogenic belt that witnessed four major episodes of accretion and collision between discrete continental blocks, such as the North China Block, North Qinling Block and the South China Block.

TL;DR: The North China Craton (NCC) has experienced a complex geological evolution since the early Precambrian, and carries important records of secular changes in tectonics and metallogeny.
