Assembly, accretion, and break-up of the Palaeo-Mesoproterozoic Columbia supercontinent: Record in the North China Craton revisited
Columbia is a Palaeo-Mesoproterozoic supercontinent that was assembled during global 2.0-1.8Ga collisional events, underwent long-lived, subduction-related accretion at key continental margins in the period 1.8-1.3Ga, commenced to fragment ∼1.6Ga ago, and finally broke up at ∼1.3Ga.

Columbia is a Palaeo-Mesoproterozoic supercontinent that was assembled during global 2.0-1.8Ga collisional events, underwent long-lived, subduction-related accretion at key continental margins in the period 1.8-1.3Ga, commenced to fragment ∼1.6Ga ago, and finally broke up at ∼1.3Ga. Similar to most other cratonic blocks (Laurentia, Baltica, Siberia, Amazonia, West African, South Africa, India, Australia, and Antarctica), the North China Craton records the history of assembly, accretion, and break-up of the Columbia supercontinent. New data indicate that the Archaean to Palaeoproterozoic basement of the North China Craton was assembled by microcontinental blocks along three Palaeoproterozoic collisional belts: the Khondalite Belt, the Jiao-Liao-Ji Belt, and the Trans-North China Orogen. The Khondalite Belt was formed by collision between the Yinshan and Ordos blocks and was amalgamated to form the Western Block at ∼1.95Ga. The Eastern Block underwent Palaeoproterozoic rifting at 2.2-1.9Ga to break-up into the Longgang and Nangrim blocks; then the rift basin/incipient ocean closed attending subduction and collision to form the Jiao-Liao-Ji Belt at ∼1.9Ga.
