摘要

在Sierra Tejeda,我们只能区分两个alpujarrides构造单元,Almijara和Robledal,简化了之前的划分。水文地质数据支持这一解释,因为它们指出了大理石占据的两个区域(Tejeda和Rodaderos区)之间可能的水力连接,这两个区域以前被认为是不同的构造单元,这使得它不太可能。在Robledal单元中,岩性序列下部的片麻岩的存在使其与Guajares-Jubrique/ Los Reales群(Alpujarride杂岩的上组)的其他单元相关联。在过去的几十年里,我们一直在研究不同构造单元之间的相互作用,这些构造单元是由不同的构造单元组成的,这些构造单元是由不同的构造单元组成的。此外,还显示了位于Sierra Tejeda北部的新的E-O断层,这促进了Betica内部带向西的移动。= =地理= =根据美国人口普查,该地区的总面积为,其中土地和(2.641平方公里)水。= =地理= =根据美国人口普查局的数据,这个县的总面积,其中土地和(1.)水。= =地理= =根据美国人口普查,这个县的总面积为,其中土地和(2.641平方公里)水。在Robledal单元中,片晶片在岩石序列的下部与Guajares-Jubrique/Los Reales组(Alpujarride单元的上部)的其他单元相关。Extensional deformations are superposed over, but,这些磁发生器,根据实地观测,they have not the enormous重视attributed to察in previous models, as they do not differentiate new磁发生器,至少in this area。= =地理= =根据美国人口普查局的数据,该县的总面积为,其中土地和(1.)水。

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.
