Mesozoic Neozoic terrigenous sequence of Biyang fault depression in Nanxiang Basin, is treated as a case to study influential factors of terrigenous sequence formation and development. Basement structural subsidence, sedimentary source recharge, palaeoclimate transformation and lacustrine level change are the four factors which are very important to control terrigenous sequence development in fault depressed lacustrince basin. In Biyang fault depressed lacustrince basin, regional tectonism brought about...
