Our work shows that, because of the large-scale dextral slip along the Red River fault zone, the northwest Yunnan rift-basin region, the extensive tectonics, are formed on the end since Miocene. The extensive basins have spread southeastwardly from the Miocene to the Quaternary. Typical strike-slip deformation appears at the center segment of fault zone. The granitic body in the late-Yanshan period, the coal-basins and the drainage of Lishe River are dextrally offset in-phase. The dextral displacement since the Pliocene can be 30~32km.
