• ( 4 ) the formation and growth of structural traps and stratigraphic - unconformity traps in the area is controlled by three compressive stages of silurian - devonian , late permian - tertiary and oligocene - quaternary ; non - structural and compound traps mainly grew in the early paleozoic . structural traps mostly grew in the late paleozoic and the cenozoic and mostly grew on the north and south belts ; non - structural traps mostly grew in the northern area of the hetian concave . most traps in the area formed or typed at last in the himalayan episode , dispersed on the north and south belts
