Geology Of The Iberian Peninsula
The geology of the Iberian Peninsula consists of the study of the rock formations on the Iberian Peninsula, connected to the rest of the European landmass by the Pyrenees. The peninsula contains rocks from every geological period from the Ediacaran to the Quaternary, and many types of rock are represented. World-class mineral deposits are also found there. The core of the Iberian Peninsula consists of a Hercynian cratonic block known as the Iberian Massif. On the northeast, this is bounded by the Pyrenean fold belt, and on the southeast, it is bounded by the Betic fold mountain chain. These two mountain chains are part of the Alpine belt. To the west, the peninsula is delimited by the continental boundary formed by the opening of the Atlantic Ocean. The Hercynian fold belt is mostly buried by Mesozoic and Cenozoic cover rocks to the east but nevertheless outcrops through the Iberian Chain and the Catalan Coastal Ranges. Iberian Massif The Iberian Massif consists of roc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geological Units Of The Iberian Peninsula EN
Geology (). is a branch of natural science concerned with the Earth and other astronomical objects, the rocks of which they are composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology. It is integrated with Earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface and the processes that have shaped that structure. Geologists study the mineralogical composition of rocks in order to get insight into their history of formation. Geology determines the relative ages of rocks found at a given location; geochemistry (a branch of geology) determines their Geochronology, absolute ages. By combining various petrological, crystallographic, and paleontological tools, geologists are able to chronicle the geological history of the Earth as a whole. One aspect is to demonstrate the age of the Earth. Geology provides evidence for plate tectonics, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Catalan Coastal Range
The Catalan Coastal Range (, ) is a system of mountain ranges running parallel to the Mediterranean Sea coast in Catalonia, Spain. It is part of the Catalan Mediterranean System. Its main axis runs between the Foix River and the Roses Gulf and the average altitude is around 500 m. The highest point is 763 m at the Montnegre. Mountain ranges From North to South: * Montgrí * Gavarres * Massís de l'Ardenya * Serra de Marina * Montnegre Massif * Serra del Corredor * Serra de Sant Mateu *Serra de la Conreria * Serra de Collserola * Massís del Garraf Further south there are certain coastal mountain ranges like los Dedalts, Moles del Taix and Serra de la Mar in the Tivissa-Vandellòs Mountains and the Serra del Montsià that are included in the Catalan Pre-Coastal Range owing to the geological continuity with that range despite their seaside location.

Antiform
In structural geology, an anticline is a type of fold that is an arch-like shape and has its oldest beds at its core, whereas a syncline is the inverse of an anticline. A typical anticline is convex up in which the hinge or crest is the location where the curvature is greatest, and the limbs are the sides of the fold that dip away from the hinge. Anticlines can be recognized and differentiated from antiforms by a sequence of rock layers that become progressively older toward the center of the fold. Therefore, if age relationships between various rock strata are unknown, the term antiform should be used. The progressing age of the rock strata towards the core and uplifted center, are the trademark indications for evidence of anticlines on a geological map. These formations occur because anticlinal ridges typically develop above thrust faults during crustal deformations. The uplifted core of the fold causes compression of strata that preferentially erodes to a deeper ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Window (geology)

If an erosional hole is created in the nappe that is called a window. A klippe is a solitary outcrop of the nappe in the middle of autochthonous material. A tectonics, tectonic window, or fenster (lit. "window" in German language, German), is a geology, geologic structure formed by erosion or normal faulting on a thrust fault, thrust system. In such a system the rock mass ( fault (geology), hanging wall block) that has been transported by movement along the thrust is called a nappe. When erosion or normal faulting produces a hole in the nappe where the underlying autochthonous (i.e. un-transported) rocks crop out this is called a window. Klippen are also a feature near windows. The klippe is the remnant portion of a nappe after erosion has removed connecting portions of the nappe. This process results in an out ...

Terrane
In geology, a terrane (; in full, a tectonostratigraphic terrane) is a crust fragment formed on a tectonic plate (or broken off from it) and accreted or " sutured" to crust lying on another plate. The crustal block or fragment preserves its distinctive geologic history, which is different from the surrounding areas—hence the term "exotic" terrane. The suture zone between a terrane and the crust it attaches to is usually identifiable as a fault. A sedimentary deposit that buries the contact of the terrane with adjacent rock is called an overlap formation. An igneous intrusion that has intruded and obscured the contact of a terrane with adjacent rock is called a stitching pluton. There is also an older usage of the term ''terrane'', which described a series of related rock formations or an area with a preponderance of a particular rock or rock group. Overview A tectonostratigraphic terrane did not necessarily originate as an independent microplate, since it may not contain ...

Laurentia
Laurentia or the North American craton is a large continental craton that forms the Geology of North America, ancient geological core of North America. Many times in its past, Laurentia has been a separate continent, as it is now in the form of North America, although originally it also included the cratonic areas of Greenland and the Hebridean terrane in northwest Scotland. During other times in its past, Laurentia has been part of larger continents and supercontinents and consists of many smaller terranes assembled on a network of early Proterozoic Orogenic belt, orogenic belts. Small microcontinents and oceanic islands collided with and Suture (geology), sutured onto the ever-growing Laurentia, and together formed the stable Precambrian craton seen today. Etymology The craton is named after the Laurentian Shield, through the Laurentian Mountains, which received their name from the St. Lawrence River, named after Saint Lawrence of Rome.

Gondwana
Gondwana ( ; ) was a large landmass, sometimes referred to as a supercontinent. The remnants of Gondwana make up around two-thirds of today's continental area, including South America, Africa, Antarctica, Australia (continent), Australia, Zealandia, Arabian Peninsula, Arabia, and the Indian subcontinent. Gondwana was formed by the Accretion (geology), accretion of several cratons (large stable blocks of the Earth's crust), beginning with the East African Orogeny, the collision of India and Geography of Madagascar, Madagascar with East Africa, and culminating in with the overlapping Brasiliano orogeny, Brasiliano and Kuunga orogeny, Kuunga orogenies, the collision of South America with Africa, and the addition of Australia and Antarctica, respectively. Eventually, Gondwana became the largest piece of continental crust of the Paleozoic Era, covering an area of some , about one-fifth of the Earth's surface. It fused with Laurasia during the Carboniferous to form Pan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Precambrian
The Precambrian ( ; or pre-Cambrian, sometimes abbreviated pC, or Cryptozoic) is the earliest part of Earth's history, set before the current Phanerozoic Eon. The Precambrian is so named because it preceded the Cambrian, the first period of the Phanerozoic Eon, which is named after Cambria, the Latinized name for Wales, where rocks from this age were first studied. The Precambrian accounts for 88% of the Earth's geologic time. The Precambrian is an informal unit of geologic time, subdivided into three eons ( Hadean, Archean, Proterozoic) of the geologic time scale. It spans from the formation of Earth about 4.6 billion years ago ( Ga) to the beginning of the Cambrian Period, about million years ago ( Ma), when hard-shelled creatures first appeared in abundance. Overview Relatively little is known about the Precambrian, despite it making up roughly seven-eighths of the Earth's history, and what is known has largely been discovered from the 1960s onwards. The Precambrian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lisbon
Lisbon ( ; ) is the capital and largest city of Portugal, with an estimated population of 567,131, as of 2023, within its administrative limits and 3,028,000 within the Lisbon Metropolitan Area, metropolis, as of 2025. Lisbon is mainland Europe's westernmost capital city (second overall after Reykjavík, Reykjavik), and the only one along the Atlantic coast, the others (Reykjavik and Dublin) being on islands. The city lies in the western portion of the Iberian Peninsula, on the northern shore of the River Tagus. The western portion of its metro area, the Portuguese Riviera, hosts the westernmost point of Continental Europe, culminating at Cabo da Roca. Lisbon is one of the List of oldest continuously inhabited cities, oldest cities in the world and the second-oldest European capital city (after Athens), predating other modern European capitals by centuries.

Montes De Toledo
The Montes de Toledo is one of the main systems of mountain ranges in the Iberian Peninsula. They divide the drainage basin of the Tagus from the basin of the Guadiana. The highest peak is La Villuerca, which is high. Description The Montes de Toledo are located in the central regions of the Iberian Peninsula, cutting transversally from east to west across the lower portion of the Meseta Central. The length of the Montes de Toledo is and their maximum width up to near Sonseca and Puertollano. The eastern Montes de Toledo ranges form one of the natural limits of the historical La Mancha region in Castile-La Mancha and the western end, including the ranges forming the broader Montes de Toledo, reaches into Portalegre District, Portugal. Geology Geologically the series of ranges making up the system were formed by Alpine orogeny, but unlike the Central System further north the Montes de Toledo comprise an older terrain of elongated belts of folded and thrust faulted sediment ...
