| Dual Foreland Basin Model of Continent-Continent Collision Orogenic Belt:Evidence from Dabieshan, Himalayan and Uralian Orogenic Belts |
| Different genetic types of foreland basins can be formed in different tectonic stages. Based on studies of some well-known continental collision orogenic belts, the authors divided the tectonic evolution of the continental collision orogenic belt into continent-continent amalgamation and large-scale intracontinental overthrust (intracontinental subduction)stages. The foreland basin formed on the basis of the subducted passive continental margin during the amalgamation stage was named "proto-foreland basin", whereas that formed in the inner part of the subducted continent during the large-scale intracontinental overthrust stage was named "outer foreland basin", which is more distant from the main suture zone than the proto-foreland basin. The proto-foreland basin and the outer foreland basin are two genetic types of peripheral foreland basins, which are formed in different tectonic stages of one continental collision orogenic belt, and produce the “dual foreland basin of one continental orogenic belt that however is not simply a single foreland basin of the generally accepted conception. The dual foreland basin is an important characteristic of the peripheral system as compared with the retro-arc system. |
