Carnian (Late Triassic) C-isotope excursions, environmental changes, and biotic turnover: a global perturbation of the Earth's surface system

Abstract

Here we present the second part of the special thematic issue on the Carnian Pluvial Episode (CPE). In this issue, two works on terrestrial sedimentological and floral changes linked to the CPE, and new carbon isotope records from Oman and China are presented. The papers published in this issue complement those contained in volume 175 issue 6; they altogether give an almost complete vision of the state-of-the-art about the CPE, including the many conundrums.

Revision of the Conodont Mockina slovakensis and Its Paleogeographic Implications for the Upper Triassic Intraplatform Basins of the Alps

“…The Carnian Prealps is characterized by the presence of mainly shallow-water carbonate platform facies flanked by basinal ones, Upper Triassic-Lower Jurassic in age (Carulli et al, 2000). The Norian sedimentary succession started with the deposition of the peritidal deposits of the shallow-water carbonate platform represented by the Dolomia Principale Formation, followed by the Dachstein Limestone Formation, above a flat paleotopography originated by the partial filling of the pre-existing Carnian basins due to the increased terrigenous input during the Carnian Pluvial Event (e.g., Dal Corso et al, 2019;Rigo at al., 2007;Simms and Ruffell, 1989). During the Norian a series of NNE-SSW fault-bounded intraplatform basins were formed by an extensional tectonic phase.…”
