Abstract

Abstract: A research has been performed on the structural style in the northern margin of Chaidam basin, with analyses made on the formative background, patterns of geometric spreading in the plane and in the section, and zonation of the structural fea-tures. The main thrust-slip fault belts and the nappe structure
zones, thrust sheets and low strain regions lying in between the main thrust-slip fault belts are described in detail. Field obser-vations and experimental modeling have been used to deduce the origination-evolution mode and formative mechanism of the nappe structures. It is pointed out that the thrust nappe struc-ture belts and the hidden thrust fore-borderlands are favorable
prospects for hydrocarbon exploration in the area.

Key words: Chaidam basin, structural style, thrust -slip, mechanism, experimental modeling, exploration prospect
