3. 2. The first study of the micro-fauna of middle Cambrian olistoliths in the Argentine Precordillera

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Elise Fahlgren; Maria Tranvik; [2015]
   Keywords : Olistolith; Burgess Shale-type preservation; middle Cambrian; Precordillera; Micropaleontology;

   Abstract : This study implies a survey of a somewhat unexplored Cambrian carbonate formation in the Argentine Precordillera (AP) located in western Argentina, close to the city of San José de Jáchal. The carbonate platform of the AP is a unique piece of the South American geology and is in this study partly surveyed and compared with the Stephen Formation of northern Canada, a middle Cambrian unit renowned for its contents of exceptionally well preserved soft bodied fossils named the Burgess Shale biota.

   Keywords : Ordovician; Latorpian; Volkhovian; Kundan; Aserian; conodonts; biostratigraphy; Parapaltodus n. sp. A; Texania sp. A; Tamsalu; Estonia; Earth and Environmental Sciences;

   Abstract : This investigation examines the distribution of conodont elements in the Early to early Middle Ordovician Latorpian, Volkhovian, Kundan and Aserian stages of the Tamsalu drill core in central Estonia. Slightly more than 24, 600 conodont elements from 17 samples were examined, and the biostratigraphic results were compared to previous works on conodont biostratigraphy from localities in Estonia, Russia and Öland, Sweden.
