Compression and inversion action make series of traps, tectonic traps and stratigraphy traps are the primary trap types, Tectonic traps can be classified into anticlinal traps (compressional anticlinal trap, drape anticlinal trap, faulted anticlinal trap) and fault block trap (scalariform fault block trap, arcuate fault block trap, crossed fault block trap). Stratigraphy traps can be classified into stratigraphic onlap trap and stratigraphic erosion unconformity trap.
