Tres Vírgenes
Tres Vírgenes is a complex of volcanoes located in the Mulegé Municipality in the state of Baja California Sur, on the Baja California Peninsula in northwestern Mexico. This Volcano is part of a volcanic ridge that extends from Baja California towards the Guaymas Basin. It is composed of three volcanoes, aligned northeast–southwest, with El Viejo, the oldest, to the northeast, El Azufre in the middle, and the youngest, El Vírgen, to the southwest. El Vírgen, being by far the most conspicuous of the three, is commonly known as "Las Tres Vírgenes". Geological Background Volcán Las Tres Vírgenes is part of a cluster that includes the central vent structure of El Azufre and El Viejo. The off-shore volcanic ridges extend from Tres Vírgenes–Aguajito–La Reforma towards sea-floor spreading centers in the Guayamas basin. It is located within the Gulf of California rift zone. It is a part of a volcanic ridge that extends from the eastern coast of Baja California towards ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tephra
Tephra is fragmental material produced by a volcanic eruption regardless of composition, fragment size, or emplacement mechanism. Volcanologists also refer to airborne fragments as pyroclasts. Once clasts have fallen to the ground, they remain as tephra unless hot enough to fuse into pyroclastic rock or tuff. Tephrochronology is a geochronological technique that uses discrete layers of tephra—volcanic ash from a single eruption—to create a chronological framework in which paleoenvironmental or archaeological records can be placed. When a volcano explodes, it releases a variety of tephra including ash, cinders, and blocks. These layers settle on the land and, over time, sedimentation occurs incorporating these tephra layers into the geologic record. Often, when a volcano explodes, biological organisms are killed and their remains are buried within the tephra layer. These fossils are later dated by scientists to determine the age of the fossil and its place within the geolo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountains Of Baja California Sur
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain ...

Stratovolcanoes Of Mexico
A stratovolcano, also known as a composite volcano, is a Volcanic cone, conical volcano built up by many layers (strata) of hardened lava and tephra. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile with a summit crater and periodic intervals of explosive eruptions and effusive eruptions, although some have collapsed summit craters called calderas. The lava flowing from stratovolcanoes typically cools and hardens before spreading far, due to high viscosity. The magma forming this lava is often felsic, having high-to-intermediate levels of silica (as in rhyolite, dacite, or andesite), with lesser amounts of less-viscous Igneous rock#Mineralogical classification, mafic magma. Extensive felsic lava flows are uncommon, but have travelled as far as . Stratovolcanoes are sometimes called composite volcanoes because of their composite stratified structure, built up from sequential outpourings of erupted materials. They are among the most common types of v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Volcanoes In Mexico
Types of volcanoes There are multiple types of volcanoes in Mexico. Volcanoes can be of different types such as cinder cone volcanoes, composite volcanoes, shield volcanoes, and lava domes. Each of these variations of volcanos forms in its own way. Cinder cone volcanoes are the simplest type of volcano. This volcano forms from particles of solidified lava that ejected from a single vent. When the lava is eruptive and blows into the air, it separates into small fragments that solidify and fall around the central vent to form an oval cone at the top of the volcano. “Composite volcanoes or stratovolcanoes, make up some of the world’s most memorable mountains: Mount Rainier, Mount Fuji, and Mount Cotopaxi.” These volcanoes are very steep sided and symmetrical, in a cone shape. They have a conduit system which allows the magma to flow from deep within the Earth’s surface. They have many vents within the volcano which allows the lava to break through the walls, which allows ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanoes Of East-central Baja California
The volcanoes of east-central Baja California are located on the Baja California Peninsula near the Gulf of California, in the state of Baja California Sur, in Mexico. Geography Baja California is a peninsula in Mexico, bordering the Pacific Ocean and the Gulf of California. It is made up primarily of mountains, and some coastal plains. The mountain ranges in Baja California, connected to the Pacific Coast Ranges, extend from the north-eastern to the south-western part of the peninsula. Out of the 24 named ranges, the Sierra de Juárez and the Sierra San Pedro Mártir, the highest range in Baja California, are the two most significant. The slopes of the ranges vary depending on location; the slopes on the western side are gentler than those on the east. Coastal plains are mostly found in the south-west regions on the peninsula. In the center of Baja California, volcanic activity is found mostly near the San Ignacio area. The landscape is a patchwork of lava flows and the harden ...

Ferdinand Konščak
Fernando Consag, known in his native Croatian as Ferdinand Konščak (December 2, 1703 – September 10, 1759), was a Croatian Jesuit missionary, explorer and cartographer, who spent most of his life in Mexico, in Baja California. Education Consag was born in Varaždin, Croatia, and attended primary and secondary school in his native city. At sixteen he finished the expected grades and was admitted to the novitiate of the Society of Jesus in Trencsén, Hungary (now Trenčín, Slovakia), where he stayed for two years. He was then sent to Leoben in Styria to study classics, stylistics, and rhetoric. Later he studied philosophy in Graz, Austria and in 1725–1726 he lectured on the elements of grammar at the Jesuit Academy in Zagreb in Croatia. In 1726–1727 he taught classical studies at a secondary school in Buda in Hungary. In 1728 Consag published a collection of poems titled ''Nagadia versibus latinus'', which is kept at Budapest. From 1727 to 1729 he studied theology at the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Croats
The Croats (; hr, Hrvati ) are a South Slavic ethnic group who share a common Croatian ancestry, culture, history and language. They are also a recognized minority in a number of neighboring countries, namely Austria, the Czech Republic, Germany, Hungary, Italy, Montenegro, Romania, Serbia, Slovakia and Slovenia. Due to political, social and economic reasons, many Croats migrated to North and South America as well as New Zealand and later Australia, establishing a diaspora in the aftermath of World War II, with grassroots assistance from earlier communities and the Roman Catholic Church. In Croatia (the nation state), 3.9 million people identify themselves as Croats, and constitute about 90.4% of the population. Another 553,000 live in Bosnia and Herzegovina, where they are one of the three constituent ethnic groups, predominantly living in Western Herzegovina, Central Bosnia and Bosnian Posavina. The minority in Serbia number about 70,000, mostly in Vojvodina. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
