Abstract:
The early Cretaceous structure of NE China was a result of slab‐rollback‐driven extensional tectonics, characteristic of Western Pacific‐type continental margins. Oblique docking of a microcontinent along the Asian active margin in the early Late Cretaceous induced a compressional stress regime that brought about an Andean‐type continental margin development. Partitioning of contractional–transpressional strain across NE China produced a retroarc foreland basin system, comprising, from east to west, an orogenic wedge, a foredeep (Songliao basin), a forebulge (Great Xing'an Range) and a back‐bulge depozone (Hailar and Erlian basins). A sub‐circular lacustrine depozone in the pre‐existing Songliao basin evolved into a NNE ‐trending depocentre near the forebulge and acquired a westward flowing fluvial–deltaic drainage system during the Campanian. Development of this retroarc foreland basin system signals a significant tectonic switch from a Western Pacific‐type to an Andean‐type continental margin evolution in the geological history of East Asia.
