East Qinling-Dabashan area is one of the important places for the study of the Early Paleozoic crustal evolution in East China. This book will detail the 16 Cambrian sections in the area and systematically describe trilobites found there; the 81 genera or subgenera and 161 species or subspecies (or undetermined and indelinite species) blonging respectively to 4 orders, 4 suborders, 14 superfamilies, 36 families, in which there are 2 new families, 12 new genera (or subgenera) and 71 new species. Based on this , the sequence of the Cambrian system in each stratigraphic areas is reconstructed in which there are 2 new groups, 12 new formations and 20 trilobite assemblage zones (or zones) established; many genera and species of agnositids, present in upper Middle Cambrian, provide facility for intercontinental correlation of the trillobite zones; in addition, 7 maps of lithofacies and paleogeography have been made. The study of the Cambrian strata, lithofacies, paleogeography and trilobites in this area is of great significance for a better understading of the trilobite geographic proincialization, the Cambrian crustal volution and the distribution law of the useful mineral resoures in the black rock series.
There are 24 plates, 58 tex-figures and 19 tables included in the book.
