Post-conference fieldtrip, October 21-24, 2019: Ediacaran and Terreneuvian strata surrounding the Villuercas-Ibores-Jara UNESCO Global Geopark

Description (Dublin Core)

One of the corners of the geographical maps that link the provinces of Badajoz, Cáceres and Toledo contains some key outcrops necessary to understand the Ediacaran-Cambrian transition in the Central-Iberian Zone. In the cores of the Extremenian Anticlinorium and the Ibor and Valdelacasa anticlines, the Lower Alcudian-Domo Extremeño Supergroup (including the diamictites of the Orellana Formation), the most spectacular microbial reefs with Cloudina of the Villarta Formation, and the palaeoichnological base of the Cambrian in the Arrocampo Formation (both the Villarta and Arrocampo formations belong to the Ibor Group) stand out. The exposures that were traditionally considered as representatives of the Precambrian-Cambrian boundary and base of the Cordubian regional Stage are located in the lower member of the Pusa Formation, unconformably overlying the Ibor Group, and are considered at present as intra-Terreneuvian in age.
