Abstract

Abstract

The Kelasu triangle zone occurs under the Paleogene evaporites in Kelasu anticline zone of Kuqa thrust-and-fold belts, Tarim basin (Northwest China). The triangle zone was about to start originally in the middle Miocene, developed between the Paleogene evaporites and the Jurassic coal-bearing strata, and fell under Ⅱ-type of triangle zones. While in the Pliocene, the Kelasu triangle zone was broken through at the bottom. The tectonic fronts of the Kuqa thrust-and-fold belts expanded to the Qiuli Tagh anticline zone. It is discovered that the development of the Kelasu triangle zone is related to the evolution of an overpressure envelop, and the broken layer is assumed to coincide with a mechanical boundary related to the smectite to illite transition lain under the Paleogene evaporites. The deep traps of the Kelasu triangle zone are potential targets that should be distinguished from strike-slip faults such as transfer zones for hydrocarbon exploration.
