小行星9417895 最近从土耳其的两个海相剖面和纽瓦克裂谷盆地的一个较厚的陆相(湖相)剖面中获得的高质量卡尼-诺利磁性地层不容易对比。 即使是两个土耳其部分之间的相关性也是有问题的,并且假设这两个浓缩部分在晚三叠世时位于相反的半球。 在Silica Brezova(斯洛伐克)200米厚的Carnian-Norian(上三叠统)剖面提供了解决Carnian-Norian磁性地层对比中不确定性的机会。 Silica Brezova剖面包含所有卡尼晚期和Norian牙形刺带,其厚度非常大(未凝缩),为"Hallstatt石灰岩"相。 牙形石蚀变指数接近1,表明包含该剖面的逆冲单元没有明显的埋藏。 对Silica Brezova剖面中段(Lacian)35m的磁性地层学进行了初步研究,获得了明确的极性分带和正褶皱试验。 200米硅石Brezova部分的磁性地层学和生物地层学应提供从Neward盆地到海洋领域的高分辨率旋回地层学的第一个相关性,这对于建立连接海洋和非海洋地层的综合晚三叠世时间尺度至关重要。
英文摘要
9417895 Channell High quality Carnian-Norian magnetostratigraphies derived recently from two marine sections in Turkey and a thick continental (lacustrine) section in the Newark Rift Basin are not easily correlated. The correlation even between the two Turkish sections is problematic, and is facilitated by supposing that the two condensed sections were in opposite hemispheres in Late Triassic time. A 200m thick Carnian-Norian (Upper Triassic) section at Silica Brezova (Slovakia) provides the opportunity to resolve the uncertainties in Carnian-Norian magnetostratigraphic correlations. The Silica Brezova section contains all Late Carnian and Norian conodont zones in an exceptionally thick (uncondensed) section of "Hallstatt Limestone" facies. The conodont alteration indices are close to 1, indicating no appreciable burial of the thrust unit which contains the section. A pilot magnetostratigraphic study on a 35m interval from the middle (Lacian) part of the Silica Brezova section has yielded a clear polarity zonation and a positive fold test. Magnetostratigraphy and biostratigraphy of the 200m Silica Brezova section should provide a first correlation of the high resolution cyclostratigraphy from the Neward Basin to the marine realm which is essential to the development of an integrated Late Triassic timescale linking marine and non-marine stratigraphies.
