Historia de la morfogénesis granítica

[EN] From the moment a granitic magma begins to cool until it is solidified it is subjected to stress and strain, producing the various discontinuities that can be seen in the finally exposed rock. When as a result of the erosion of superincumbent rocks the granite is at or near the land surface these discontinuities are exploited by weathering. Such features, and particularly those related to fractures or diaclases, outline forms that are considered here as primary endogenous forms. Once the rock is in the earth surface, various external agencies first soil weathering and later others as gravity, rivers, waves, glaciers, frost, wind, attack the rock to produce new suites of forms that are considered here as primary exogenous either etched or subaerial features. Such primary forms, both endogenous and exogenous, can evolve morphologically further as a result of subaerial weathering and erosion, becoming secondary endogenous or secondary exogenous forms. Exceptionally, some primary, either exogenous or endogenous, features can survive to successive morphogenetic episodes either below sedimentary burial or just subaerially without appreciable modification by external agencies being considered as inherited forms. Only the discernment of all these types of landforms allows the complete understanding of the geomorphological history of the area in which they occur.

Análisis de los conciertos de abono de la Orquesta Filarmónica de Gran Canaria desde la temporada 1980/81 hasta la temporada 2010/2011

[ES]La Fundación Orquesta Filarmónica de Gran Canaria es una de las instituciones insulares más respetada y cercana a la sociedad grancanaria por la labor que desempeña. Presentamos una aproximación a la misma, centrándonos especialmente en el análisis de los conciertos de abono ya que son la actividad central alrededor de la cual gira la actividad artística de la OFGC, además de diversa información novedosa y útil que ayudará a conocer la trayectoria de la Orquesta grancanaria. [EN]The Gran Canaria Philharmonic Orchestra Foundation is one of the most respected and well liked institutions in Gran Canaria society, for the service that it gives. We will study and analize the orchestra´s main and most important activity, its season concerts, around which all its different activities are based. New information will show the history of the Gran Canaria Philharmonic Orchestra in a different light.
