摘要

根据最近的U-Pb锆石辐射年龄、碳酸盐岩为主的地层的相互关系以及标志火山-沉积杂岩顶部的重叠模式,对东比利牛斯山脉中暴露的埃迪卡拉-下奥陶统序列进行了更新和修正。与蒙塔涅-诺伊尔(法国中部南部地块)和撒丁岛邻近的华力西期前露头的地层比较与i)在埃迪卡拉-寒武纪边界层附近没有卡多米亚变形有关;ii)与埃迪卡拉纪-寒武纪过渡期碳酸盐岩生产有关的幕式、与卡多米亚纪有关的酸性主导火山活动的存在,类似于在北部的诺伊山记录的火山活动;以及iii)在诺伊尔山和撒丁岛可能缺乏古章阶(晚寒武纪3)退积浅滩杂岩。

Review of the Ediacaran-Lower Ordovician (pre-Sardic) stratigraphic framework of the Eastern Pyrenees, southwestern Europe
The Ediacaran-Lower Ordovician successions exposed in the Eastern Pyrenees are updated and revised based on recent U-Pb zircon radiometric ages, intertonguing relationships of carbonate-dominated strata, and onlapping patterns marking the top of volcano-sedimentary complexes. A stratigraphic comparison with neighbouring pre-Variscan outcrops from the Montagne Noire (southern French Massif Central) and Sardinia is related to i) the absence of Cadomian deformation close to the Ediacaran-Cambrian boundary interval; ii) the presence of an episodic, Cadomian-related, acidic-dominant volcanism related to carbonate production punctuating the Ediacaran-Cambrian transition, similar to that recorded in the northern Montagne Noire; and iii) the lack of Guzhangian (Late Cambrian Epoch 3) regressive shoal complexes present in the Montagne Noire and probably in Sardinia.
