The well-known gravity flow sediments were formed by the debris, sliding and turbidity flows in Late Jurassic-Early Cretaceous in Shalagang mining area of Jomzi basin in southern Tibet, which consisted of the slope clastic rocks and interbeds of siliceous rocks and limestones. Three kind lithofacies assemblages of upper slope, lower slope and submarine fan emerged in the slope. The upper slope was characterized by all kinds of sliding sediments and lower slope by all kinds of debris flow sediments. The submarine fan that had completely inner, middle and outer fan can be divided into progressive and regressive sequence, which were composed of sandstone bodies formed by turbidity flow.
