Trough-like and comb-like folds make up the Jura-type folds. From the traditional view, the Jura-type folds are formed by decollement effect and the typical example is that when above rigid rocks (basal) there exists the soft bed, and the stratum above the soft bed performs “tablecloth” type sliding, and thus forms the trough-like or comb-like fold. Based on the field survey of trough-like folds in eastern Guizhou Province, some characteristics of trough-like folds were figured out: 1) the stratum in the core of trough-like syncline is thicker than that in the limb of trough-like syncline and that in the core of anticline; 2) the multi-stage activated longitudinal faults whose strikes are consistent with those of the hinges of folds developed across the core of trough-like syncline; and 3) the deformation of stratum in the core of syncline is more complex than that in the core of anticline, and the limbs of syncline are steep.
