Abstract The Taho Formation in western Shikoku Island, Japan, consists of Triassic carbonates that formed on a seamount the Panthalassic Ocean. In order to investigate stratigraphy and paleoceanography this carbonate succession, we analyzed biostratigraphy chemostratigraphy 17.6 m‐thick section upper at stratotype area Tahokamigumi, Seiyo City. This comprises bioclastic limestone containing biv...

Abstract Energy dispersive X-ray microscopy (EDX) is a widely available, inexpensive method of characterizing the in-situ elemental composition samples in Earth and life sciences. Common protocols textbooks focussing on material sciences address EDX analysis metallic that can be polished perfectly, whereas geoscientists often investigate specimens with prominent topography composed light, diffi...

Permian brachiopods from Oman are well-known as valuable tools for correlation and palaeobiogeographical palaeoclimatic reconstructions. Here, we describe a new brachiopod fauna the Qarari Unit of allochthonous Batain Group in northeast Oman. Brachiopods were collected four localities: Wadi Khawr al Jaramah (WKJ), Jebel (JQ1), X (JX3) Shiya (SH11). The age fossiliferous localities is wellconstr...

Magnetostratigraphic studies of the Ordovician provide evidence for nature core-mantle boundary interactions, and means dating correlation across differing environmental regimes. We new magnetostratigraphic data from Middle Upper Ordovician, compiling this into a polarity chronostratigraphic scale Dapingian to Hirnantian interval. The are derived Backside Beck Cheney Longville sections in Brita...
