Ancient sediments reflect the compositions of old eroded continental crustal material and preserve geochemical signatures of paleo-tectonic and volcanic events. Geochemical study of such sediments provides insight into tectonic events that shaped the face of the Earth. Nd isotopes are best suited for such studies because rare earth elements (REE), specifically Sm and Nd are not fractionated dur...

The area between the villages of Reka in Idrijca Valley, Bukovo and Zakriž near Cerkno belongs geographically geotectonically to Dinarides. consists two large inner thrust blocks Trnovo nappe, which were thrusted for tens kilometers direction SW their present position. They are overlain by Tolmin lowest unit Southern Alps. nappe was from N S a smaller intermediate sheet. In western part contact...

In previous investigations, nearshore pyritic shale horizons in the Mid-Proterozoic Newland Formation were interpreted to be due to "non-clastic" colloidal iron supply by streams. New data on the chemical composition of shales in the Newland Formation support this interpretation. In these shales, Fe and Al show a positively correlated trend that intercepts the Fe axis above the origin. These re...

The strata in the Shita Mountain, Yunkai region, are predominantly composed of clastic rocks with intercalated limestones. However, precise stratigraphic age remains uncertain due to scarcity fossils. Previously, conglomerate layers this region were considered indicative Yunan Orogeny during Cambrian–Ordovician transition. through identification 12 lithofacies types and 5 combinations Mountain ...
