Trigonirhynchia palentina n. sp. y T. celtiberica n. sp. son formas de rinconelidos proximas a la especie armoricana T. fallaciosa, y de similar edad que ella, Praguiense inferior. El genero Eucharitina, bien conocido en el Dominio paleo-geografico del Viejo Mundo, se identifica y describe formalmente por primera vez en el area estudiada, donde esta representado por tres especies: E. bultyncki n. sp., de la parte alta del Lochkoviense inferior del Guadarrama oriental y E. carlsi n. sp., de la parte baja del Praguiense inferior y E. cf. eucharis, de fines del Praguiense medio, de la Cordillera Iberica Oriental. Se menciona y figura tambien material de comparacion de la especie armoricana, E. oehlerti. Se propone el nuevo genero del Orden Athyri-dida Chopinia, constituido solo por su especie-tipo, C. petercarlsi n. sp., del Lochkoviense superior o del Praguiense inferior de Palencia y Celtiberia. La concha muy transversa, de contorno eliptico, con buen desarrollo del area cardinal y ornamentacion de lamelas concentricas escamosas en Chopinia lo aproxima a la Subfamilia Plicathyridinae, en particular al genero Anathyris. Sin embargo, la ausencia de elementos radiales (pliegues y surco ventral) en la concha y la comisura anterior no invaginada po-dria indicar que Chopinia es un tronco ancestral, primitivo, de la subfamilia, cuya ulterior evolucion hasta llegar a Anathyris en el Emsiense se desconoce. EnglishSeveral new Lower Devonian (Lochkovian-Pragian) brachiopod taxa from the Canta-bro-Celtiberian region of the Ibero-Armorican basin are described and figured. These taxa support the occurrence and continuity of the Iberoarmorican basin along time. Trigonirhynchia palentina n. sp. and T. celtiberica n. sp. are Lower Pragian rhynchonellid species close to the Armorican species T. fallaciosa. The genus Eucharitina, well-known along the paleogeographic Old World Domain, is formally identified and described for the first time in the studied region. There, it is represented by three species, E. bultyncki n. sp. from the upper part of the Lower Lochkovian in Eastern Guadarrama, and E. carlsi n. sp., lowermost Pragian and E. cf. eucharis, middle Pragian of the Eastern Iberian Chain. Comparison material of the Armorican species E. oehlerti are also mentioned and figured. A new Athyrididae genus, Chopinia, constituted only by the type-species C. petercarlsi n. sp. from the upper Lochkovian or the lower Pragian of Palencia and Celtiberia is proposed here. The very transverse elliptical outline, good development of the cardinal area and ornamentation of concentric, squamose growth lamellae, are features close to those of the Subfamily Plicathyridinae, in particular to the genus Anathyris.

This is one of the most perceptible characteristics of a beach. Sand color can be altered after a nourishment work. This type of works is becoming more and more popular since they represent a good tool for preserving beaches from erosion. However, only little (or none) attention has been paid to sand color during nourishment works. Colors of the sands from the Belgian coast were determined in the Cielab space, together with their granulometry and composition. Color coordinates range between 50 and 60 for L*, 0.5 to 4.0 for a*, and 10.5 to 16.5 for b*. The composition shows a dominant quartz fraction, followed by shell fragments and finally rock fragments. Granulometry is rather homogeneous, being the grain distribution for the east part of the coast narrower than for the west coast.

Esta ultima es la que se empleara en este estudio. Se trata de una aproximacion empirica que permite estimar, mediante la asignacion de una puntuacion, la calidad del macizo rocoso, con el objetivo de conocer su grado de estabilidad ante la ejecucion de una excavacion subterranea. En la presente investigacion se aplica el indice Q al estudio de la estabilidad de galerias y filones de una pequena mina de oro en el Canton de Ponce Enriquez, Ecuador. En este trabajo se propone un nuevo grafico empirico tomando para ello otros anteriores y los resultados de la evaluacion de tal manera que pueda determinarse el factor de seguridad y el maximo vano estable que pueda abrirse en minas de este tipo. Una de las principales aportaciones del trabajo es la de validar el indice de Barton a huecos pequenos. EnglishRock mass classifications are used throughout the world since the 1970’s. It is a methodology for the prefeasibility assessment of the stability of underground openings. The most used are the Bieniawski’s RMR and the Barton’s Q index. The latter is the one we have used in this study. It is an empirical approach that gives a numerical score to the rock mass quality to determine the degree of stability or reinforcement required. In this research, the Q index is applied to assess the stability of galleries and veins in a small gold mine in Canton Ponce Enriquez, Ecuador. A new empirical chart has been established using previous ones and considering the results of the study. This chart can be used to determine the safety factor and stable maximum span that can be opened in vein-mines of this type. One of the main contributions of the work is to validate the Barton index to small holes.","PeriodicalId":252745,"journal":{"name":"Trabajos de Geologia","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123994146","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
