摘要(Abstract):
华北地台北部、东北部冶里组至亮甲山组下部 (相当于牙形类 Fryxellodontus inornatus亚带底至 Scalpel-lodus tersus带 )和扬子地台中部雾渡河组上部至分乡组均可分为 4个正层序。C.proavus带至 C.angulatus带下部碳酸盐岩δ1 3C值与澳大利亚黑山、美国 L awson Cove和哈萨克斯坦 Batyrbay剖面同期地层一样出现 3次同步性上升、下降旋回性变化 ,可作为洲际之间寒武系 -奥陶系界线地层对比的工具之一。根据牙形类、笔石等生物地层和碳同位素化学地层 ,华北与扬子地台之间 4个三级层序在时限上相互可对比。从晚寒武世末至早奥陶世早期(Fryxellodontus inornatus亚带底至 Paltodusdeltifer带 )期间发生了 6次海平面升降事件 :1)晚寒武世末期凤山组与冶里组之间和雾渡河组上部 (C.proavus带下部 )的升降事件 (相当于美国 L ange Ranch升降事件 ) ; 2 )冶里组一段与二段和雾渡河组与西陵峡组之间 (C.proavus带与 C.intermedius带之间 )的升降事件 ; 3)扬子地台西陵峡组上部海退事件 (相当于澳大利亚 Aceroceras海退事件 ) ; 4)西陵峡组与南津关组之间 (C.lindstromi带与 C.an-gulatus带之间 )升降事件 ,相当于澳大利亚黑山升降事件 (BMEE) ; 5 )冶里组二段与三段和南津关组与分乡组之间升降事件 ,Ps
