Orogrande Basin
The Orogrande Basin is a geologic province in southern New Mexico and western Texas. It includes Doña Ana, Sierra, Socorro, Lincoln, and Otero Counties in New Mexico and El Paso County, Texas. The province takes its name from the community of Orogrande, New Mexico. Geology The province is named for the Orogrande Basin, which was a shallow marine basin during the Carboniferous. This basin was one of several basins that opened along the southwestern margin of the North American craton due to crustal stress from the Ouachita Orogeny. At this time, this area was very close to the equator. Up to of limestones and shales were deposited. These included sediments from a Carboniferous mountain range, the Pedernal Uplift, located to the east. A narrow shelf, the Sacramento Shelf, was located between the basin and mountain range, and formations in this area from the Carboniferous are notable for their algal mounds. This steep shelf margin gave way further west to a gently-inclined ra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orogrande Map
Orogrande is an unincorporated community in Otero County, New Mexico, United States, located at a latitude of 32.37111 and a longitude of -106.08389 in the Jarilla Mountains of the Tularosa Basin on U.S. 54 between El Paso, Texas and Alamogordo. Originally a mining town named Jarilla Junction due to its proximity to the Jarilla Mountains, established in 1905, the town was renamed Orogrande (Spanish for ''big gold'') in 1906 and is not far from similar mining towns (now completely abandoned ghost towns) named Brice and Ohaysi. The population soared to approximately 2000 as the result of a gold rush that occurred in 1905, but quickly collapsed almost to the point of depopulation when the gold deposits proved much less abundant than expected. There are still numerous abandoned mines in the area which fall under the jurisdiction of the Bureau of Land Management. Other land around Orogrande is part of a military reservation under the control of Fort Bliss. The community had a populatio ...

Carboniferous
The Carboniferous ( ) is a geologic period and system of the Paleozoic that spans 60 million years from the end of the Devonian Period million years ago ( Mya), to the beginning of the Permian Period, million years ago. The name ''Carboniferous'' means "coal-bearing", from the Latin '' carbō'' ("coal") and '' ferō'' ("bear, carry"), and refers to the many coal beds formed globally during that time. The first of the modern 'system' names, it was coined by geologists William Conybeare and William Phillips in 1822, based on a study of the British rock succession. The Carboniferous is often treated in North America as two geological periods, the earlier Mississippian and the later Pennsylvanian. Terrestrial animal life was well established by the Carboniferous Period. Tetrapods (four limbed vertebrates), which had originated from lobe-finned fish during the preceding Devonian, became pentadactylous in and diversified during the Carboniferous, including early amphibian line ...

Geologic Provinces Of Texas
Geology () is a branch of natural science concerned with Earth and other astronomical objects, the features or rocks of which it is composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology, and so is treated as one major aspect of integrated 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. It also provides tools to determine the relative and absolute ages of rocks found in a given location, and also to describe the histories of those rocks. By combining these tools, geologists are able to chronicle the geological history of the Earth as a whole, and also to demonstrate the age of the Earth. Geology provides the primary evidence for plate tectonics, the evolutionary history of life, and the Earth's past climates. Geologists broadly study the properties and processes of Earth ...

Tularosa Basin
The Tularosa Basin is a graben basin in the Basin and Range Province and within the Chihuahuan Desert, east of the Rio Grande in southern New Mexico and West Texas, in the Southwestern United States. Geography The Tularosa Basin is located primarily in Otero County. It covers about (35% larger than Connecticut). It lies between the Sacramento Mountains to the east, and the San Andres and Oscura Mountains to the west. The basin stretches about north–south, and at its widest is about east-west. It is geologically considered part of the Rio Grande Rift zone, which widens there due to the slight clockwise rotation of the Colorado Plateau tectonic plate. Notable features of the basin include White Sands National Park, Oliver Lee Memorial State Park, the Carrizozo Malpais lava flow, Holloman Air Force Base, and the White Sands Missile Range with the historic Trinity nuclear test Site. Tularosa Creek flows westward into the Tularosa Basin just north of the village of Tularo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pennsylvanian (geology)
The Pennsylvanian ( , also known as Upper Carboniferous or Late Carboniferous) is, in the International Commission on Stratigraphy, ICS geologic timescale, the younger of two period (geology), subperiods (or upper of two system (stratigraphy), subsystems) of the Carboniferous Period. It lasted from roughly . As with most other geochronology, geochronologic units, the stratum, rock beds that define the Pennsylvanian are well identified, but the exact date of the start and end are uncertain by a few hundred thousand years. The Pennsylvanian is named after the U.S. state of Pennsylvania, where the coal-productive beds of this age are widespread. The division between Pennsylvanian and Mississippian (geology), Mississippian comes from North American stratigraphy. In North America, where the early Carboniferous beds are primarily marine limestones, the Pennsylvanian was in the past treated as a full-fledged geologic period between the Mississippian and the Permian. In parts of Europe, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gobbler Formation
The Gobbler Formation is a geologic formation in the Sacramento Mountains of New Mexico. It preserves fossils dating back to the Moscovian Age of the Pennsylvanian Period. Description The Gobbler Formation consists of a lower section of of quartz sandstone and limestone and an upper section of over of shales and quartz sandstones. The lower sandstone beds are well-sorted and the limestone includes black masses of chert. These beds intruded by sills possibly of Tertiary age. The upper beds interfinger with limestone assigned to the Bug Scuffle Limestone Member of the Gobbler Formation. The total thickness is . The formation overlies the Lake Valley Limestone, from which it is separated by a subaerial erosion surface with paleochannels as deep as The Gobbler Formation underlies the Beeman Formation. The Bug Scuffle Limestone Member contains parasequences thick whose uppermost beds show isotopic evidence of subaerial exposure. The formation is prominently exposed at Oliv ...

Shale
Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2 Si2 O5( OH)4) and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite.Blatt, Harvey and Robert J. Tracy (1996) ''Petrology: Igneous, Sedimentary and Metamorphic'', 2nd ed., Freeman, pp. 281–292 Shale is characterized by its tendency to split into thin layers ( laminae) less than one centimeter in thickness. This property is called '' fissility''. Shale is the most common sedimentary rock. The term ''shale'' is sometimes applied more broadly, as essentially a synonym for mudrock, rather than in the more narrow sense of clay-rich fissile mudrock. Texture Shale typically exhibits varying degrees of fissility. Because of the parallel orientation of clay mineral flakes in shale, it breaks into thin layers, often splintery and usually parallel to the otherwise indistinguishable beddin ...

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] |
Ouachita Orogeny
The Ouachita orogeny was a mountain-building event that resulted in the folding and faulting of strata currently exposed in the Ouachita Mountains. The more extensive Ouachita system extends from the current range in Arkansas and Oklahoma southeast to the Black Warrior Basin in Alabama and to the southwest through the Llano, Marathon, and Solitario uplifts in Texas on into Coahuila and Chihuahua in Mexico. The Ouachita System Pre-collision formations The region during the early Paleozoic lay off the coast of the southern portion of Laurentia, in what is now the southern United States. Laurentia straddled the equator at the time and the Rheic Ocean was to the south of Laurentia. Through the Ordovician, Silurian, Devonian, and early Carboniferous, marine sedimentation left extensive deposits of black shale, quartzose sandstone, and chert beds. During the Mississippian, a flysch sequence with dark shales and graywackes was deposited. Lenses of silicic tuff exist as evidenc ...

Geologic Province
A geologic province is a spatial entity with common geologic attributes. A province may include a single dominant structural element such as a basin or a fold belt, or a number of contiguous related elements. Adjoining provinces may be similar in structure but be considered separate due to differing histories. Geologic provinces by origin Geologic provinces by resources Some studies classify provinces based upon mineral resources, such as mineral deposits. There are a particularly large number of provinces identified worldwide for petroleum and other mineral fuels, such as the Niger Delta petroleum province.
