Abstract

Abstract: The structural styles in Liaohe basin are classified into basement-involved structures and caprock de- tached structures. The former are subdivided into six types including stepped expanding structure, extensional normal fault structural combination, drape structure, transfer zones, wrench structure and positive inversion structure. The latter are subdivided into two types, i.e., detached normal fault structure, diapir structure. There were multi-stage tectonics in this area, thus some structures are superimposed. The characteristics of trap developments vary from one style to another. Based on the structural styles and trap characteristics, the traps in Liaohe basin are classified into structural trap and non-structural trap.

Key words: Liaohe basin, structural type, structural feature, trap
