摘要
在伊比利亚地块的伊比利亚中部地区，被解释为潮汐和浅海碳酸盐矿床的Los navalucilllos组包含了一个重要的古海藻动物组合。这里描述了靠近La Nava de Ricomalillo地区的地层最西端露头的两个新的特征暴露:(i) La Estrella，由于附近的深成杂岩，岩石受到接触变质作用的强烈影响;(ii) Finca - Higueruela演替，没有钙微生物-古藻黏结岩，尽管有明显的叠层石和肿瘤等微生物。
El sector más occidental de la Formación de Los Navalucillos, Cámbrico inferior: microbialitas en yacimientos mareales de la Zona Centroibérica, Monte de Toledo, España
In the Central Iberian Zone of the Iberian Massif, the Los Navalucillos Formation, interpreted as tidal and shallow-marine carbonate deposits, contains a significant archaeocyathan faunal assemblage. Two new characteristic exposures are described here from the westernmost outcrops of the formation, close to La Nava de Ricomalillo area: (i) La Estrella, where the rocks are strongly affected by contact metamorphism due to the nearby plutonic complex; and (ii) the Finca Higueruela succession, without calcimicrobial-archaeocyathan boundstones, although different microbialites as stromatolites and oncolites are conspicuous.
期刊介绍：
Since 1945 Estudios Geologicos publishes original research works, as well as reviews, about any topic on Earth Sciences.
Estudios Geologicos is published as one yearly volume, divided into two half-yearly issues. It is edited by the Spanish National Research Council (Consejo Superior de Investigaciones Científicas, CSIC) at the Instituto de Geociencias (CSIC-UCM).
Estudios Geologicos provides free access to full-text articles through this electronic edition. Accepted articles appear online as "Forthcoming articles" as soon as the galley proofs have been approved by the authors and the Editor-in-Chief. No changes can be made after online publication.
