Barranco del Forau de O y puertos de Gias, Clarabide y O (Oô); Benasque, Huesca, Aragón, España


The Forau de O (Oô in french) ravine is a lateral valley of the Estós Valley, which empties into it on its left side, from the North. It covers from the Estós Valley to the French border, covering the Forau de O, the Gías and O lakes, and the peaks and passes of Clarabide, Gourgs Blancs and Tuca de O. In the area there outcrops a granite of the porphyritic type (porphyroid granodiorites), with large orthoclase crystals of up to 7 cm, generally twinned according to the Carlsbad law. The weathering has exposed the feldspar crystals on the surfaces of the rock and has even freed them completely. Other minerals present in the granodiorite are quartz, biotite, andesine and other sodium plagioclases; as accessories rutile and sphene.

El barranco del Forau de O (de Oô en francés) es un valle lateral del Valle de Estós, que desagua en éste por su lado izquierdo, desde el Norte. Abarca desde el valle de Estós hasta la frontera Francesa, cubriendo el Forau de O, los ibones de Gías ó de O, y los picos y puertos de Clarabide, Gourgs Blancs y Tuca de O. En la zona aflora un granito de tipo porfiroide (granodiorita porfiroide), con grandes cristales de ortosa de hasta 7 cm, generalmente maclados según la ley de Carlsbad. La meteorización ha expuesto los cristales de feldespato en las superficies de la roca e incluso ha llegado a liberarlos por completo. Otros minerales presentes en la granodiorita son cuarzo, biotita, andesina y otras plagioclasas sódicas; como accesorios rutilo y esfena.
