Abstract

Guided by the high-resolution sequence stratigraphy theory, and making the middle-term cyclic sequence as mapping unit, this paper studied the paleogeography and sand body distribution characteristics. The result shows that the Upper Jurassic Suining Formation in the middle section of western Sichuan Depression can be divided into one longterm sequence (LSC1) and three middle-term sequences (MSC1-MSC3). The front of Longmen Mountain developed alluvial fan group, and braided river delta deposition is manifested in multiple braided river delta overlay during the period of the MSC1-MSC3. The depositions are mainly of braided river delta-lacustrine deposition during the period of the MSC1-MSC2, alluvial fan only changed in the size and location, and sand bodies mainly distributed in the front of Longmen Mountain and Zhongjiang-Huilong area. During the period of M3, the deposition changed into thick and large-scale braided river delta plain deposition, and sand bodies mainly distributed in Pixian-Wenjiang-Dayi area.
