Serra De L'Espina
Serra de l'Espina is a limestone mountain chain located at the north-eastern end of the Iberian System. It connects the Ports de Tortosa-Beseit mountain massif with the Catalan Pre-Coastal Range. Geography The Serra de l'Espina ridge's highest point is L'Espina (1,181.6 m). Other high peaks are Mola Carrascosa (1.025 m), Cap de la Faixa Blanca (1.023 m), Tossal de Montclí (960 m) and La Moleta d'Alfara (812 m). On the eastern side of the range are some visible barren patches, devoid of vegetation owing to high winds, the very large Rases del Maraco, or Les Rases, at the southern end and Erms de Canduca further north. Other noteworthy places are Solana de les Feixes, the Cova dels Adells karstic cave and the ruins of Mas del Roig, an ancient farmhouse. The Serra de Paüls mountain range is located to the north of this range.

Ports De Tortosa-Beseit
Ports de Tortosa-Beseit (), also known as Ports de Beseit, or simply as Els Ports or Lo Port by locals, is a limestone mountain massif located at the north-eastern end of the Sistema Ibérico, a complex system of mountain ranges and massifs in the centre of the Iberian Peninsula. Its highest point is Mont Caro, 1,441 m. Rivers such as the Matarranya and the Sénia have their source in these mountains. Description At the 1350 m high Tossal dels Tres Reis (Peak of the Three Kings), where the borders of the ancient Kingdoms of Valencia, Catalonia and Aragon meet, there is a cairn marking the meeting point of the ancient three kingdoms of the Crown of Aragon. It is mostly a limestone massif, with many steep cliffs, jagged peaks, deep valleys, shafts and caves. The area is mostly uninhabited except for small villages. These mountains were one of the last redoubts of the Spanish Maquis in the 1940s and 50s. Ecology One of the largest colonies of griffon vultures in Europe, as well ...

Karstic
Karst is a topography formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves. It has also been documented for more weathering-resistant rocks, such as quartzite, given the right conditions. Subterranean drainage may limit surface water, with few to no rivers or lakes. However, in regions where the dissolved bedrock is covered (perhaps by debris) or confined by one or more superimposed non-soluble rock strata, distinctive karst features may occur only at subsurface levels and can be totally missing above ground. The study of ''paleokarst'' (buried karst in the stratigraphic column) is important in petroleum geology because as much as 50% of the world's hydrocarbon reserves are hosted in carbonate rock, and much of this is found in porous karst systems. Etymology The English word ''karst'' was borrowed from German in the late 19th century, which entered German much earlier. ...

Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sistema Ibérico
The Iberian System ( es, Sistema Ibérico, ) is one of the major systems of mountain ranges in Spain. It consists of a vast and complex area of mostly relatively high and rugged mountain chains and massifs located in the central region of the Iberian Peninsula, but reaching almost the Mediterranean coast in the Valencian Community in the east. The system is hydrographically important, as it separates the watersheds of most of the major rivers in Spain and Portugal, including the Ebro basin from the basins of the Douro, Tagus, Guadiana (Záncara- Gigüela), Júcar and Turia. There are important mining areas in some of the ranges such as Sierra Menera, Sierra de Arcos and Sierra de San Just, making the system one of the chief mining regions in Spain since ancient times. One of the comarcas of Aragon located in the Iberian System was given the name of Cuencas Mineras, lit. 'Mining Basins', since mining is the main activity in the comarca.

Catalan Pre-Coastal Range
The Catalan Pre-Coastal Range ( ca, Serralada Prelitoral Catalana) is a system of mountain ranges running parallel to the Mediterranean Sea coast in Catalonia. It is part of the Catalan Mediterranean System. Its main axis runs between the Catalan Transversal Range and the Serra de l'Espina, which connects with the Ports de Tortosa-Beseit, part of the Iberian System. The highest point is 1.706,7 m at the Montseny Massif. Mountain ranges From North to South: * Les Guilleries * Montseny Massif * Sant Llorenç de Munt *Montserrat * Serra de Queralt, Bellprat * Picorandan * Serra de Prades * Montsant *Serra de Llaberia * Tivissa-Vandellòs Mountains. Towards the southern end of the Catalan Pre-Coastal Range there are certain coastal mountain ranges like los Dedalts, Moles del Taix and Serra de la Mar which —lacking a traditional geographical name as a group— have been recently named as the 'Tivissa-Vandellòs Mountains' ''(Muntanyes de Tivissa-Vandellòs)''.

La Moleta (Alfara De Carles)
La Moleta or Moleta d'Alfara is a mountain of the Serra de l'Espina, a northern prolongation of the Ports de Tortosa-Beseit, Catalonia, Spain. It has an elevation of 812 metres above sea level.. La Moleta rises about 5 km NNW above the village of Alfara de Carles. It is readily identifiable from afar, for its striking squarish shape contrasts sharply with the other summits of the mountain chain.

Cave
A cave or cavern is a natural void in the ground, specifically a space large enough for a human to enter. Caves often form by the weathering of rock and often extend deep underground. The word ''cave'' can refer to smaller openings such as sea caves, rock shelters, and grottos, that extend a relatively short distance into the rock and they are called ''exogene'' caves. Caves which extend further underground than the opening is wide are called ''endogene'' caves. Speleology is the science of exploration and study of all aspects of caves and the cave environment. Visiting or exploring caves for recreation may be called ''caving'', ''potholing'', or ''spelunking''. Formation types The formation and development of caves is known as ''speleogenesis''; it can occur over the course of millions of years. Caves can range widely in size, and are formed by various geological processes. These may involve a combination of chemical processes, erosion by water, tectonic forces, microorgani ...
