1 引言风暴床是由风暴产生的陆架和坡道上的独特相标准，例如热带纬度的气旋和飓风以及中高纬度的暴风雪(Tucker & Wright，1990；Flugel，2004)。 Ager (1973)将风暴床定义为风暴床，其通常特征是尖锐和侵蚀性的基底，内部结构包括贝壳堆积、分级和平坦层理以及平行和交叉层理，顶部呈现波纹层理和洞穴(Aigner，1985；Flugel，2004；Dattilo等，2012)。显生宙碳酸盐环境中暴风岩丰富且分布广泛(e.g. Einsele & Seilacher, 1982; Flugel, 2004)。风暴岩的沉积模式和生物分布可以为其沉积过程、古环境、古地理位置甚至地层比较等方面提供重要信息(Johnson, 1989; Lehman & Pope, 1989; Flugel, 2004; Jin et al., 2013)。风暴贝层是一种常见的风暴岩类型，以贝壳堆积为特征，在奥陶纪晚期（Lehman & Pope，1989；Davis，1999；Jin et al.，2013）、志留纪早期（Johnson，1989；Li & Rong，2007；Jin，2008）和石炭纪早期（Jeffery & Aigner， 1982；Butts，2005）和温室气候期间，如奥陶纪中期（McFarland 等，1999）、二叠纪晚期（Simoes & Kowalewski，1998）、三叠纪早期
1. IntroductionStorm beds are distinct facies criteria on shelves and ramps, which are generated by storm winds, such as cyclones and hurricanes in tropical latitudes and blizzards in middle and high latitudes (Tucker & Wright, 1990; Flugel, 2004). Ager (1973) defined storm beds as tempestites that are commonly characterized by sharp and erosional base, internal structures including accumulations of shells, graded and flat bedding and parallel and cross lamination, and ripple bedding and burrowing presented at the top part (Aigner, 1985; Flugel, 2004; Dattilo et al., 2012). Tempestites are abundant and widely distributed in carbonate environments during the Phanerozoic (e.g. Einsele & Seilacher, 1982; Flugel, 2004). The sedimentary patterns and biotic distributions of tempestites could provide important information in aspects of their depositional process, palaeoenvironment, palaeogeographical location and even stratigraphic comparison (Johnson, 1989; Lehman & Pope, 1989; Flugel, 2004; Jin et al., 2013). Storm shell beds, which are one common type of tempestites and featured by accumulation of shells, were documented during the icehouse periods of the late Ordovician (Lehman & Pope, 1989; Davis, 1999; Jin et al., 2013), early Silurian (Johnson, 1989; Li & Rong, 2007; Jin, 2008) and early Carboniferous (Jeffery & Aigner, 1982; Butts, 2005) and during greenhouse climate, as in the middle Ordovician (McFarland et al., 1999), late Permian (Simoes & Kowalewski, 1998), early Triass
