The Apillapampa section (Bolivia): field trip accomplished in July 2023-a report of “Gondwana to Euramerica Correlations Working Group"

Abstract

The Permian marine to transitional deposits at Apillapampa in Bolivia matches Permian Stratigraphy Working Group (WG) goals because of co-occurrence of several species of conodonts and fusulinids with abundant other taxa including plants and palynology, as well as volcanic tuffs (some U-Pb dated). ‘Bridge taxa’ occur throughout different Gondwanan provinces and support correlations with northern hemisphere Cisuralian ‘standard sections’ (including GSSPs) in Russia, USA, and China (Cisterna et al. 2022, in Permophiles 72). As part of an on-going project on Carboniferous – Permian fossiliferous successions of Bolivia (Grader et al., 2008; di Pasquo et al., 2009, 2013, 2014, 2015, 2019, 2022), a field trip to the Apillapampa section was carried out in July 2023.
