El objetivo general de este trabajo fin de máster es el análisis y síntesis de los principales estudios realizados, hasta la fecha, así como la profundización en la investigación sobre la importante tasa de subsidencia que está experimentando la cuenca del Alto Guadalentín durante las últimas décadas. El objetivo general anteriormente expuesto se puede dividir en los siguientes objetivos específicos: • Confirmación de que la subsidencia del Valle del Guadalentín está provocada, principalmente, por la sobreexplotación de acuíferos, y en todo caso, detectar si existe alguna causa secundaria, como la tectónica. • Justificación de los motivos por los cuáles existen dificultades para encontrar los signos externos de subsidencia, del apartado anterior, en el Valle del Guadalentín a diferencia de otros casos del mismo tipo de subsidencia en el mundo. • Localización e identificación de casos concretos de consecuencias físicas del fenómeno de la subsidencia en el terreno, tales como grietas y hundimientos en el terreno, patologías en construcciones y variaciones anómalas de la pendiente en parcelas y canales de riego.

This layer is a georeferenced raster image of the historic paper map entitled: Carta hidrográfica del Valle de México, levantada de órden del Ministerio de Fomento por los ingenieros Miguel Iglesias, Ramon Almaraz, Mariano Santa-María y José Antonio de la Peña, bajo la direccion del Ingeniero Geógrafo Francisco Diaz Covarrubias antiguos alumnos del Colegio Nacional de Minería 1862 ; Ramón Almaraz delineo. It was published by La Sociedad in 1863. Scale 1:80,000. Covers the Valley of Mexico region. Map in Spanish. The image inside the map neatline is georeferenced to the surface of the earth and fit to the 'World Mercator' projection. All map collar and inset information is also available as part of the raster image, including any inset maps, profiles, statistical tables, directories, text, illustrations, index maps, legends, or other information associated with the principal map. This map shows features such as drainage, canals, aqueducts, cities, towns, and other human settlements, selected buildings, ranches and properties, built-up areas, roads, ground cover, and more. Relief shown by hachures. Depths shown by soundings. Includes 2 profiles: Plano de Comparacion -- Perfil de los acueductos with chart entitled "Tabla comparativa de alturas de los puntos principales del perfil." This layer is part of a selection of digitally scanned and georeferenced historic maps from the Harvard Map Collection and the Harvard University Library as part of the Open Collections Program at Harvard University project: Organizing Our World: Sponsored Exploration and Scientific Discovery in the Modern Age. Maps selected for the project correspond to various expeditions and represent a range of regions, originators, ground condition dates, scales, and purposes.
Geological map of Potter Peninsula (King George Island, South Shetland Islands, Antarctic Peninsula)
Resumo:
We present here a new geological map of Potter Peninsula (King George Island, South Shetland Islands). Like on adjacent Barton Peninsula, the morphology on Potter Peninsula is predominantly characterized by a glacial landscape with abrasion platforms offshore, in parts steep cliffs along the coast, and a rather smooth, hilly countryside in the interior. Potter Peninsula forms part of the downthrown Warszawa Block. The volcanic sequence cropping out here belongs to the King George Island Supergroup, with an observed local minimum thickness of approx. 90 m (Kraus 2005). The most prominent morphological feature is Three Brothers Hill (196 m), a well known andesitic plug showing conspicuous columnar jointing. It marks the final stage of activity of a Paleogene volcano, whose eruption products (lava flows and pyroclastic rocks), together with hypabyssal intrusions related to the volcanism, make up most of the lithology observed on Potter Peninsula (Kraus 2005). The Three Brothers Hill volcanic complex is eroded down to its deepest levels. Thus, the stratigraphically deepest units from the initial phase of volcanic activity are cropping out in some parts (Kraus & del Valle, in Wienke et al. 2008). The lithology on Potter Peninsula comprises lava flows (~50%), pyroclastic rocks (ash-fallout, pyroclastic flow deposits, volcanic breccia and agglomerates, ~30%) and hypabyssal intrusions (dykes, sills and small subvolcanic intrusive bodies, ~20%). 40Ar/39Ar datings carried out on magmatic dykes from Potter Peninsula indicate a short, but intense intrusive event during the Lutetian (Kraus et al. 2007).
