Late Jurassic Superposed folds developed in the foreland structural belt of Mts Dabashan are one of the most typical examples of regional or map-scale buckle superposition structures in the world, characterized by very conspicuous and spectacular interference pattern. A 1:10000 geological mapping was conducted in the northwestern Dabashan where the interference between two almost intersecting folds occurs, aiming at detailed geometric and kinematic analysis of the varied inventory of outcrop-scale cross-folds. The structural analysis indicates that the two discrete folding phases, respectively, related to late middle Triassic and late Jurassic isolated tectonic events are mainly responsible for shallow buckle folds in the study area. In light of the the detailed geometric and kinematic analysis of the various folds and their corresponding dissimilar lineation patterns, three types and ten modes of fold superposition have been differentiated according to interference pattern and Mechanisms of superposed folding. The results show that the SN- to NNW-trending folds(F2) orthogonally overprint the early EW-trending ones (F1). The latter ones formed in the late Jurassic and constitute the major structural elements of the Mts Dabashan. And in situation of non-coaxial bulk deformation, in which the NW-trending folds(F3) are superposed to SN-NNW-trending folds(F2) at a small angle to each other in the west- central study area. The superposed deformation mainly causes the juxtaposing and refolding.
