TEMPESTITES IN THE CAMBRIAN STRATA IN DABEIWANG,XUZHOU,JIANGSU

The tempestites in the Cambrian carbonate rocks in Dabeiwang,Xuzhou,Jiangsu may be divided into deeper-water tempestites,shallow-water tempestites,shallowest-water or intertidal tempestites,of which the shallow-water tempestites may further be subdivided into nearshore,inshore(backwash)and suprabeach shallow-water tempestites. The tempestites in distinctive sedimentary facies in the study area are often associated with the sedimentary rocks formed not only under the normal hydrodynamic conditions but also with those produced by biological and biochemical processes.They may have impor-tant significance for the correlation of the regional strata and recognition of the tempestites in carbonate rocks.
