Understanding the Geological Structures of Argentina
Precambrian Structures: Formed resistant crystalline rocks that were part of Pangea. These are called cratons. The Puna Tandilla, Pampas, and mountains are missionary plateau massif outcrops of Brasilia. The plateau missionary was resumed in the Mesozoic era.
Below the Chaco-Pampean plain is solid the rest of Brasilia.
The Puna is a high plateau at 3500 m above sea level, giving a mountainous and arid climate that prevents the entry stage of wet winds.
The Pampean Sierras are presented divided into 4 mountain ranges that are worn.
Tandil Saws are worn and are lower than the window. The Puna should be of a lower height, but having been pushed by the Andean orogeny, it appears more elevated.
Neocraton, the Patagonian plateau, is colliding to form the mountains of the window; now this plateau has the appearance of a hierarchy.
Paleozoic Structures: They have suffered heavy wear and consequently have rounded shapes. These structures are the highest mountains in the country. The thrust of the training received in the Andes Mountains causes the rejuvenation of these structures.
Mesozoic Structures: The missionary was a raised plateau in this era and has a large tear.
The mountains of the window are formed when the Patagonian Neocraton collided. Their age is the cause of their higher altitude.
Cenozoic Structures: The Patagonian Andes do not match their age with their height; they were formed in the Cenozoic Era and suffered effects of glaciations that caused: general subsidence of the block, deepening valleys, and transformation of the river valley to glacial lakes, presence of elongated and thinning mountain structures. Thanks to all of this characterization, we have a wet cold climate due to the moisture given by the Pacific winds entering the valleys and opening their moisture to dry to continue the Patagonian plateau.
The mountains rise in cords and are isolated, having a lower height on the eastern slopes due to the presence of orographic rain, while the western slopes are arid.
Plains: There are structures formed not by spelling movements but by the accumulation of sediment. There are 4 plains: the Pampa, Chaco, Mesopotamia, and the Paraná Delta.
Under the Pampas and Chaco plain is the sunk Brasilia Massif.
The estuaries of Corrientes are more moist due to having a freshwater reservoir in a low area that remains flooded.
The hills are small Entrerrianas elevations called blades.
Latitude: As we move from Ecuador, temperature decreases by 1°C every 180 km. Argentina has 4 climates (warm, cold, warm, or dry) that allow a variety of flora, fauna, and natural resources.
Altitude: With the increase in altitude, temperature decreases by 1°C every 180 meters. This biome determines that humid temperatures suit the mountainous environment.
Provision of Relief: Amendment to the moisture conditions in mountainous terrain must be perpendicular to the wind. The damp wind meeting the mountain must rise, changing from gaseous to liquid state, then condensing and precipitating mountain rain.
Receive slope wind: LEEWARD and BAROVENTO dry slope.
Ocean Currents: The quality of water from Ecuador raises the temperature, while cold currents moving from the pole to Ecuador decrease temperature, leading to areas of desertification.
Distance to Sea: Water absorbs and releases temperature. The water keeps the temperature stable. Nearshore areas have moderate temperatures and less variation, while areas away from the coast experience colder winters and warmer summers with more extreme temperature variations.
Pampa Checkered: Gaza Paraná rivers of silver. They are gentle hills that originated from slight elevation of the mountain dwarf and river erosion.
Depressed Pampa: West of the rolling Pampas, there is a presence of land under maximum subsidence, solid permanent ponds, and depressions with drainage difficulties, including a salt basin.
Pampa High: West of the depressed Pampa, approaching the Córdoba hills, the terrain altitude increases. It has water scarcity and the presence of salty lagoons, salt marshes, and measures.
Intraserrana: Southwest Province of Buenos Aires, gently undulating plain relief with heights of 200 meters.
Northern Andes: Gordon East. Set of high mountains in the north-south direction with elevations of more than 5500 meters.
Central Andes: From South to North, Catamarca to Neuquén, composed of the main chain and the front.
They are the highest peaks and are recognized as an arid area.
Patagonian Andes, Tierra del Fuego: Chains that are narrower and shorter in height. On land west of the fire, changes occur. This area extends into the ocean.
Mountains Rise Dyne: Saws low arranged in a north-south direction east of the eastern mountains, with heights between 1500 and 2500 meters.
Pampean Sierras: Center of the country with great antiquity, round shapes, and low altitudes in the form of blocks from north to south, and are the highest peaks.
Precordillera: A set of mountain crowns east of the mountains with flat tops.
Tandilla: Northwest-southeast south of Buenos Aires, characterized by round shapes and low height.
Ventania: Far southwest of Buenos Aires to the Atlantic coast, in the northwest-southeast direction, with sharp peaks and steep-sided jagged forms.
Famatima: Located in La Rioja, part of a spelling system compared with the Saws Pampas.
Mahuidas: A serrano system in central-southern Pampa, characterized by low isolated hills and round shapes.
Estuaries: Extensions of waterlogged areas covered by aquatic plants.
Bathed: Accumulation of temporary water in topographically high areas.
Payunia: A plateau area in southern Mendoza, extensive grounds covered with lava and volcanic cones, with extensive volcanic activity. Since 1982, this sector has been preserved as a provincial reserve, the Payen.
Mesopotamian Plain (Blades): De Montiel and large.
Paraná River Delta: The delta is always in growth because it slows down the Paraná River and deposits sediments, forming islands.
Albardón: A lowland area prone to flooding that transforms into an island as water rises.
Cañadon: An ancient and deep channel between hills and mountains.
Cuesta: Sloping land.
Skirt: Bottom of the mountain slopes.
The Puna: Arizona anthophagous Salares Cauchari and large salt.
Plateau Missionary: Known as Plateau Guaimbê.
