A Typological Calssification Os Spanish Precious Metals Deposits
Caderno Lab. Xeolóxico de Laxe Coruña. 1995. Vol. 20, pp. 253-279 A typological classification ofSpanish precious metals deposits Clasificación tipológica de los yacimientos españoles de metales nobles CASTROVIE]O, R. Last decade's intensive exploration for precious metals in Spain led to a new understanding ofvarious types ofdeposits and prospects. A summary review of recent progress is presented, allowing the systematic (typological) classification ofthe Spanish precious metals deposits shown in Table 1: 19 types are defined in the framework ofthe Iberian Geology, their exploration significance being also considered. Hypogene deposits in the Hercynian Hesperian Massif, and epithermal gold deposits in the Neogene calc-alcaline Volcanic Province ofSE Spain have been very much explored and are therefore emphasized, although their mining production is by far not to compare with the precious metals output the SWIPB (SW Iberian Pyrite Belt). IntheHesperian Massif, different metalloterts have beendemonstrated tobe related toattractiveconcentrations ofgold, bound to Hercynianshear-zones, inGalicia, in Extremadura, etc.; other concentrations (e. g., in Galicia and Asturias) are related to granite or porphyry intrusions (Salave) and skarn formations (Carlés). PGE or Platinum elements (± chromite) have been found in ophiolitic thrust complexes occurring in N Galicia, e. g. the HerbeiraMassifofthe Cabo Ortegal Complex, as had been in the 1940's in N orthern Portugal(Bragan\aand Morais complexes). Exploration for silver has demonstrated a small orebody in Fuenteheridos (Aracena, SW Spain), not minable under severe environmental constraints, but none ofthe classic Spanish silver producing districs (vein-Type deposits, e. g. Guadalcanal or Hiendelaencina) has recovered activity. Most ofthe EU (European Union) gold and silver production is won from only two types ofdeposits in the Spanish Hesperian Massif: the masive sulphides of the SWIPB, in which precious metals are won as by-products, and the related gossan deposits. -
Simulations of Mesoscale Circulations in the Center of the Iberian Peninsula for Thermal Low Pressure Conditions
880 JOURNAL OF APPLIED METEOROLOGY VOLUME 40 Simulations of Mesoscale Circulations in the Center of the Iberian Peninsula for Thermal Low Pressure Conditions. Part I: Evaluation of the Topography Vorticity-Mode Mesoscale Model FERNANDO MARTIÂN,SYLVIA N. CRESPIÂ, AND MAGDALENA PALACIOS Departmento de Impacto Ambiental de la EnergõÂa, Centro de Investigaciones EnergeÂticas, Medioambientales y TecnoloÂgicas, Madrid, Spain (Manuscript received 27 September 1999, in ®nal form 10 August 2000) ABSTRACT The Topography Vorticity-Mode Mesoscale (TVM) model has been evaluated for four different cases of thermal low pressure systems over the Iberian Peninsula. These conditions are considered to be representative of the range of summer thermal low pressure conditions in this region. Simulation results have been compared with observations obtained in two intensive experimental campaigns carried out in the Greater Madrid Area in the summer of 1992. The wind ®elds are qualitatively well simulated by the model. Detailed comparisons of the time series of simulations and observations have been carried out at several meteorological stations. For wind speed and direction, TVM results are reasonably good, although an underprediction of the daily thermal oscillation has been detected. The model reproduces the observed decoupled ¯ow in the nighttime and early morning along with the evolution of mixing layer ¯ow during the day. In addition, the model has simulated speci®c features of the observed circulations such as low-level jets and drainage, downslope, upslope, and upvalley ¯ows. The model also simulates the formation of hydrostatic mountain waves in the nighttime in some cases. 1. Introduction mal low dominates summer atmospheric conditions. In spite of the high frequency of this mesoscale pressure The Greater Madrid Area is located in a 700-m high system in the south of Europe and in other parts of the plateau at the center of the Iberian Peninsula. -
El Glaciarismo En La Península Ibérica
EL GLACIARISMO EN LA PENÍNSULA IBÉRICA EL FENÓMENO GLACIAR CUATERNARIO EN LA PENÍNSULA IBÉRICA Quaternary Glaciation in the Iberian Peninsula Eduardo Acaso Deltell (*) RESUMEN Se describe el fenómeno glaciar pleistoceno que afectó a las principales cadenas montañosas de la península. Se define el glaciarismo como de montaña con formación de glaciares de valle (donde son abundantes los aparatos de decenas de Km de longitud) y formas menores así como glaciares rocosos y, en algún caso, de montera. El mayor desarrollo se produjo en los Pirineos en donde aún existen glaciares funcionales. El modelo de evolución consta de un máximo (en torno a 70.000-38.000 BP para la cadena pirenaica) y un período de estabilización a partir del cual se da un retroceso generalizado en donde, en la mayoría de los macizos, puede hablarse de un episodio de glaciares de valle, otro de glaciares de circo y un Tardiglaciar (entre 17.300 y 9.000 BP) definido por glaciares residuales. Finalmente, en algunas ca- denas se detecta una reactivación del fenómeno glaciar durante la Pequeña Edad del Hielo (siglos XIII- XIX). ABSTRACT This is a description of the glacial processes that affected the Iberian Peninsula along the Quaternary. Mountain glaciers (valley, cirque and rock-glacier) can be identified. The maximum development was concentrated in the Pyrenees (where still survive some active glaciers) and this maximum happened ap- proximately between 70000 and 38000 years BP. Later, a retreat period affect most areas of the Iberian Peninsula, leaving a period of valley glaciers, a period of cirque glaciers and a late-glacial period (17300-9000 y BP) with only residual glaciers. -
Picos De Europa-Spain)
Geographia Technica, Special Issue, 2010, pp .6 to 11 AUTOMATIC CLOSE–RANGE PHOTOGRAMMETY TO DIGITAL TERRAIN MODEL IN ICE PATCH JOU NEGRO (PICOS DE EUROPA-SPAIN) Javier De Matías BEJARANO1, Fernando Berenguer SEMPERE1, José Juan De SANJOSÉ BLASCO1 ABSTRACT: In this paper we present a stereo feature-based method using SIFT (Scale-invariant feature transform) descriptors. We use automatic feature extractors, matching algorithms between images and techniques to produce a DTM (Digital Terrain Model) using convergent shots of an ice patch. The geomorphologic structure observed in this study is the Jou Negro ice patch (Cantabrian Mountain, Spain). Keywords: Geomorphology, Close - Range Photogrammetry, DTM, SIFT. 1. INTRODUCTION The Jou Negro cirque is located in the Picos de Europa Massif (Cantabrian Mountain) (Fig. 1), at north of Iberian Peninsula (43º12´03´´N; 4º51´12´´W). The Picos de Europa massif is an Atlantic mountain located at 20 km from the Atlantic seaboard, and reaching 2648 m a.s.l. at the Torre Cerredo peak, the highest peak of the Cantabrian Mountains. The relief of the Picos de Europa is characterized by great differences in altitude (over 1500– 2300 m), and it is the first orographic barrier facing the rain-bearing winds from the Atlantic Ocean (González, 2006; González, 2007). The climate is warm, characterised by high precipitations, reaching the 3000 mm/yr on the top. The precipitations are mainly as snow during winter period, but the rain and high cloudiness occur all year. Fig. 1 Jou Negro Situation in 17th October 2007 The Picos de Europa range consists of a succession of fault thrusts of northern dipping, calcareous rocks where the predominant rocks are limestone of Carboniferous age. -

We were quickly on our way, leaving Santander behind and doing our best to ignore the industrial sprawl of Torrelavega. We take the E70 motorway to Unquera, which is a good road, but takes us through a managed landscape, mostly large plantations of pine and eucalypt for the paper mills at Torrelavega, a relic of Franco’s reign. Roadside birds include our first Common Buzzard and Black Kite. But once off the E70 and heading south, the countryside softens and we can appreciate some of the traditional architecture of dark stone and timber with terracotta tiles, and some buildings with strong colour-washed walls – some colours more sympathetic than others! We get our first view of one of the many peaks we will see in the next few days as Penamellera looms ahead of us as we head for Panes. -
