CorrelationThe study area was situated in south of the Jiangnan Slope Belt，western Hunan（Peng 1990，1992）.It is well known as one of the most richly fossiliferous areas in China for the Middle and Late Cambrian trilobite faunas.As Cambrian trilobite faunas have been documented around the world，it has become evident that the faunas in western Hunan provide a correlative possibility for worldwide correlations（Text-figure 9）.As discussed above，18 trilobite zones were proposed for the Middle and Late Cambrian in South China（Peng，1999）.The interval with the Ptychagnostusatavus Zone（late Taijiangian Stage in South China）to the Proagnostus bulbus Zone is considered to be correlatable with the early Changhsian Stage（Middle Cambrian）in North China.The interval from the Liguagnostus reconditus Zone（early Waergangian Stage in South China）to the Leiostegium constrictum-Shenjiawania brevica Zone（late Taoyuanian Stage in South China）are considered equivalent with the Kushanian，Changshanian and Fengshanian Stage（Late Cambrian）in North China.In the study area，the topmost zone is the Eolotagnostus decorus-Kaolishaniella Zone，which is considered correlatable with the late Changshanian Stage（Late Cambrian）in North China（Peng，2000）.
As indicated above，the Aoxi Formation of the Middle Cambrian is largely unfossilifeous dolomite in northwest and western Hunan，but its stratigraphical position suggests that is correlated with the lower Changshanian Stage of North China.

3.2.1 Correlation between the study area and west Zhejiang
In the study area，Ptychagnostusatavus allows a direct correlation with the P.atavus Zone of the Yangliugang Formation of the Middle Cambrian in West Zhejiang（Text-figure 9）；the Ptagnostus punctuosus Zone in West Hunan includes Pseudophalacroma ovata［=Ps.triangularis］and Triplagnostus longitriangularis，the former（Ps.triangularis）also occurred in West Zhejiang as a zonal fossil.Many important elements of the Goniagnostus nathorsti and L.laevigata Zones of the Wangcunian Stage of West Hunan，such as：Lejopyge laevigata，L.armata，Goniagnostus（A.）spiniger，Hypagnostus parvifrons，Proceratopyge（P.）conifrons，and Fuchouia oratolimba，have also been reported from the L.armata Zone of the Upper Cambrian Yangliugang Formation in West Zhejiang.Both zones are comparable each other.As the Proagnostus bulbus Zone and the Linguagnostus reconditus Zone comprise Cyclagnostus yaogongbuensis，and Bergeronites hunanensis，these elements commonly appear in the L.sinonensis Zone of lower part of the Huayanshi Formation of West Zhejiang.These two zones are correlatable with the G.stolidotus and G.reticlatus zones，which are known as index zonal fossils for global correlation of the boundary between Middle and Upper Cambrian，and occurred in both areas.The first discovery of Erixanium in middle part of the Huaqiao Formation of the study area，suggests the subzone that bears its name in the Agnostus inexpectans-Proceratopyge protractaAssemblage Zone is correlatable with the Erixanium Zone in West Zhejiang.
As the Agnostotes clavata-Irvingella angustilimbata and Corynexochus plumula-Sinoproceratopyge cf.kiangshanensis Zone consists of Pseudaagnostus（P.）communis，Proceratopyge（S.）dubius and P.（S.）kiangshensis，Agnostotes clavata［=Pseudoglyptagnostus clavatus］，suggesting a correlation with the A.clavatus-Sinoprocertopyge kiangshanensis Zone in upper part of the Huayansi Formation in West Zhejiang.It is difficult to correlate with the L.punctatus-Hedinaspis Zone of the Xiyangshan Formation and the post A.clavata-Irvingellaangustilimbata Zone of the Bitiao Formation.The Rhaptagnostus ciliensis-Onchonotellus cf.kuruktagnostus and E.decorus-Kaolishaniella Zones may be generally compared with the lower part of the Lotagnostus punctagnostus Zone in West Zhejiang.The L.punctatus Zone-Hedinaspis regalis Zone of west Zhejiang bears L.punctatus and Ketyna zhejiangensis.These two species appeared also in the L.punctatus-H.regalis Zone in West Hunan.
