通过山西中阳柏洼坪剖面上寒武统三山子组野外剖面测量、采样和室内鉴定,建立了三山子组风暴岩的岩石学和沉积构造等沉积相标志.本研究区风暴岩具有异地近源型风暴岩沉积特征,并发育底面侵蚀形成的渠模构造.认为研究区三山子组沉积环境为开阔台地—局限台地,而不是前人认为的环陆白云岩潮坪.

Many features of storm sediments may indicate ancient water depth, but also the restoration of the ancient climate. Analysis of sedimentary basins and restoration of palaeogeography are of practical significance, especially in judging the continental tectonic nature and background. Base on the outcrop measurement, sampling and indoor identification to Upper Cambrian Sanshanzi Formation at the Baiwaping tempestite outcrop in zhongyang, Shanxi province, sedimentary facies markers that include petrology, paleontology and sedimentary structures of Sanshanzi tempestite are studied and recognized. The tempestite is characterized by allogenic and proximal storm sedimentation and develops ditch structures formed by bottom erosion. Comprehensive study suggests that the regional sedimentary environment of Sanshanzi Formation is the open platform to the restricted platform rather than the dolostone tidal flat that the previous scholars has regarded as.
