New progress in the study of the foreland thrust structural zones shows that various kinds of fault - related folds and (or) triangle zones are common in the front zones of the thrust structural zones. The multibend thrusting usually complicates the folds in the hanging wall strata due to the interference structures, which can be described by the interference of the axial surfaces associated with the fault surface bend points. In the foreland basement-involved structures, although the considerable relief bewteen the hanging wall and footwall may exist, the cover strata probably keep continuous. The growth strata can be used not only to determine the time of the structures, but also to calculate the rates of fold growth and thrusting. The folds which look like the drag folds near both sides of the thrusts actually may probably belong to the break-thrust structures.
