Abstract The Stuttgart Formation (traditionally called the Schilfsandstein) in the Germanic Basin (or Central European Basin) is a sand-rich episode representing the Mid-Carnian Episode within the gypsum-rich clayey semi-arid Keuper facies. That regional Mid-Carnian Episode is now recognized to be a manifestation of a significant global disruption of Earth's climate-ocean-biological system during the early Late Triassic. In order to provide an accurate time frame and means for high-resolution correlations among continental and marine records, we obtained a composite magnetostratigraphy spanning the entire Carnian from three boreholes in the Germanic Basin. This composite shows a good consistency with earlier published magnetostratigraphy results from South China and enables the construction of a complete Carnian polarity time scale. The upper Carnian (Tuvalian substage) portion implies that: (1) The lower quarter of the Tuvalian is dominated by a reversed-polarity magnetozone; (2) The termination of the Yangtze Platform is coeval with deposition of the Stuttgart Formation in the Germanic Basin; (3) The radiolarian-rich green-colored clay horizon of the Pignola-2 section in south Italy that is below a volcanic ash bed dated as ca. 231 Ma correlates with the D pulse of siliciclastics in Dibona section of north Italy in the middle of the Tuvalian; (4) The upper three-fourths of the Tuvalian is a major normal-polarity-dominated magnetozone; and this interval correlates with the basal E1-E6 portion of the Newark magnetic polarity reference series according to the favored correlation option; (5) The base of the Arnstadt Formation of the Germanic Basin, which had been traditionally assigned as the Carnian/Norian boundary, instead begins within the lower portion of Newark reversed-polarity zone E8r of earliest Norian according to the favored age model, although pending future verification; (6) The polarity patterns of portions of the upper Carnian from the western Tethys sections of Lower Trench at Silicka Brezova in Austria and Pizzo Mondello in Italy are verified. This Carnian composite is an enhanced polarity time scale for calibration of other global Carnian successions and events, such as the appearance of the earliest dinosaurs in fossiliferous beds of South America.

来自日耳曼盆地的卡尼阶（晚三叠世）磁地层学允许全球相关的卡尼阶中期事件

摘要 日耳曼盆地（或中欧盆地）的斯图加特组（传统上称为 Schilfsandstein）是一个富含砂岩层，代表了富含石膏的粘土质半干旱 Keuper 相中的卡尼阶中期。该区域性中卡尼期事件现在被认为是晚三叠世早期地球气候-海洋-生物系统全球严重破坏的表现。为了为大陆和海洋记录之间的高分辨率相关性提供准确的时间框架和方法，我们从日耳曼盆地的三个钻孔获得了跨越整个卡尼阶的复合磁地层。该复合材料与早期发表的华南磁地层结果具有良好的一致性，并且能够构建完整的卡尼阶极性时间尺度。上卡尼阶（图瓦利亚亚级）部分暗示：（1）图瓦利亚下四分之一以反极性磁带为主；(2)扬子地台的终点与日耳曼盆地斯图加特组的沉积同时期；(3) 意大利南部 Pignola-2 剖面的富含放射虫的绿色粘土地层，位于火山灰层之下，年代为约 10 年。231 Ma 与图瓦利亚中部意大利北部 Dibona 段的硅质碎屑 D 脉冲相关；(4) 图瓦利亚上四分之三是一个主要的以正常极性为主的磁带；根据偏好的相关选项，该区间与纽瓦克磁极性参考系列的基础 E1-E6 部分相关；(5)日耳曼盆地阿恩施塔特组的基底，传统上被指定为 Carnian/Norian 边界，但根据有利的年龄模型，它开始于最早的 Norian 的 Newark 反转极性区域 E8r 的下部，尽管有待未来验证；(6) 验证了奥地利Silicka Brezova和意大利Pizzo Mondello下海沟西特提斯剖面上卡尼阶部分的极性模式。这个卡尼阶合成是一个增强的极性时间尺度，用于校准其他全球卡尼阶序列和事件，例如南美洲化石层中最早的恐龙的出现。(6) 验证了奥地利Silicka Brezova和意大利Pizzo Mondello下海沟西特提斯剖面上卡尼阶部分的极性模式。这个卡尼阶合成是一个增强的极性时间尺度，用于校准其他全球卡尼阶序列和事件，例如南美洲化石层中最早的恐龙的出现。(6) 验证了奥地利Silicka Brezova和意大利Pizzo Mondello下海沟西特提斯剖面上卡尼阶部分的极性模式。这个卡尼阶合成是一个增强的极性时间尺度，用于校准其他全球卡尼阶序列和事件，例如南美洲化石层中最早的恐龙的出现。
