摘要

本文描述和说明了位于Villuercas-Ibores-Jara地质公园(卡塞雷斯)北部的瓜达卢佩和卡斯塔纳尔德伊博尔之间的埃迪卡拉-寒武纪过渡时期的几个地层单位。(1) Castanar组和Villarta组(Ibor组，末ediacarans和Terreneuvian)的露头及其在vendotaenids、sabellidiids和微生物礁中的含量;(ii)详细介绍了圣洛伦佐组(Terreneuvian)及其古技术内容。最后，重点介绍了armoramerican石英岩(下奥陶统)的古技术记录，主要是Cruziana和Daedalus，这些记录是地质公园中一些有地质价值的地点的特征。

Guía de campo pre-congreso, 17-18 de Octubre de 2019: Ediacárico, Paleozoico Inferior y panorámicas en el Geoparque de la UNESCO Villuercas-Ibores-Jara

Several stratigraphic units characteristic of the Ediacaran-Cambrian transition between Guadalupe and Castanar de Ibor, north of the Villuercas-Ibores-Jara Geopark (Caceres), are described and illustrated here. The outcrops of (i) the Castanar and Villarta formations (Ibor Group, terminal Ediacaran and Terreneuvian), together with their content in vendotaenids, sabelliditids and microbial reefs with Cloudina ; and (ii) the San Lorenzo Formation (Terreneuvian) and its palaeoichnological content, are detailed. Finally, the palaeoichnological record of the Armorican Quartzite (Lower Ordovician), mainly of Cruziana and Daedalus , which characterize some sites of geological interest (geosites) in the Geopark, are highlighted.
