在大量岩心观察及岩相与环境分析的基础上，首次在塔中地区志留系识别出两种风暴沉积序列，它们分别产出于海滩和陆棚环境。海滩风暴沉积序列与发育冲洗层理或槽状交错层理等的前滨上临滨砂岩共生，主要由块状或具正粒序的砾岩以及含砾砂岩、具近平行层理或丘状交错层理的砂岩等岩相单元组成。陆棚风暴沉积序列产出于下临滨内陆棚泥质岩中，自下而上由以下４个岩相单元构成：块状或具正粒序的含泥砾砂岩、具平行层理的细粉砂岩、发育浪成沙纹层理的粉砂岩及水平层理或生物扰动的泥岩。
Based on a large number of core observations and lithofacies and environmental analyzes, two storm sedimentary sequences were identified for the first time in Silurian in the Tazhong area, and they were respectively produced in the beach and in the shelf environment. The beach storm sedimentary sequence is symbiotic with the foreshore Linbin sandstone such as stratified bedding or trough cross bedding, which is mainly composed of massive or regular grain conglomerate and pebbly sandstone with near parallel bedding or mound Interlaced sandstone and other lithofacies unit composition. The sequence of the continental shelf storm sediments is produced in the Lower Shoalian continental shelf shale and consists of the following four facies units from bottom to top: massive or positively grained muddy sandstone with parallel bedding Fine siltstone, siltstone that developed waves into sandstone bedding, and mudstone that stratified or bioturbated horizontally.
