White Tank Mountains
The White Tank Mountains are a mountain range in Maricopa County, Arizona. The mountains are on the western periphery of the Phoenix metropolitan area, primarily flanked by the suburban cities of Buckeye to the southwest, and Surprise to the northeast. The mountain range is home to the White Tank Mountain Regional Park and is a regional recreation hub. The range, often referred to simply as the White Tanks, is a moderate-sized mountain range whose peaks rise to an elevation around . The range consists of a series of numerous ridges and canyons, and as such, lacks a single, prominent peak. The highest point in the range, at an elevation of , is Barry Goldwater Peak. The mountain range was formed through tectonic activities as part of a detachment fault sometime in the mid- Tertiary period, about 30 million years ago. Fairly young in geologic terms, it has not been subject to the forces of erosion for long and retains an extremely rugged topography composed of rocky fault ri ...

Mountain Range
A mountain range or hill range is a series of mountains or hills arranged in a line and connected by high ground. A mountain system or mountain belt is a group of mountain ranges with similarity in form, structure, and alignment that have arisen from the same cause, usually an orogeny. Mountain ranges are formed by a variety of geological processes, but most of the significant ones on Earth are the result of plate tectonics. Mountain ranges are also found on many planetary mass objects in the Solar System and are likely a feature of most terrestrial planets. Mountain ranges are usually segmented by highlands or mountain passes and valleys. Individual mountains within the same mountain range do not necessarily have the same geologic structure or petrology. They may be a mix of different orogenic expressions and terranes, for example thrust sheets, uplifted blocks, fold mountains, and volcanic landforms resulting in a variety of rock types. Major ranges Most geolo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Buckeye, Arizona
Buckeye is a city in Maricopa County, Arizona, Maricopa County, Arizona, United States. It is Arizona's second-largest city by area, and it is the westernmost suburb in the Phoenix Metropolitan Area. As of the 2020 United States census, 2020 census, the population was 91,502, up from 50,876 in 2010, and 6,537 in 2000. It was the fastest-growing city in the United States for 2017, 2018, and 2021. History The Buckeye area was first inhabited by the Hohokam culture. In 1877, Thomas Newt Clanton led a group of six men, three women, and ten children from Creston, Iowa, to Arizona, where they settled in the Buckeye area. Early settler Malie M. Jackson developed of the Buckeye Canal from 1884 to 1886, which he named after his home state of Ohio's moniker, "The Aesculus glabra, Buckeye State".

Surprise, Arizona
Surprise is a city in Maricopa County, in the U.S. state of Arizona. The population was 143,148 at the 2020 census, up from 117,517 in 2010 and just 30,848 in 2000. Surprise is the spring training location of the Kansas City Royals and the Texas Rangers baseball teams. History The city was founded in 1938 by Flora Mae Statler. Statler was the daughter of another Arizona pioneer, Charles Gillett who helped found Glendale, specifically as a temperance community. Gillett owned much land in Glendale as well as the Verde Valley. Surprise officials previously thought the city was founded by Statler's husband, real estate developer and state legislator Homer C. Ludden, but in 2010 property records were discovered which listed Statler owning the land before she met Ludden. Modern records often state that Statler named her land Surprise as she "would be surprised if the town ever amounted to much,” with her daughter backing this claim. This claim is contested, however, since it wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tectonic
Tectonics ( via Latin ) are the processes that result in the structure and properties of the Earth's crust and its evolution through time. The field of ''planetary tectonics'' extends the concept to other planets and moons. These processes include those of mountain-building, the growth and behavior of the strong, old cores of continents known as cratons, and the ways in which the relatively rigid plates that constitute the Earth's outer shell interact with each other. Principles of tectonics also provide a framework for understanding the earthquake and volcanic belts that directly affect much of the global population. Tectonic studies are important as guides for economic geologists searching for fossil fuels and ore deposits of metallic and nonmetallic resources. An understanding of tectonic principles can help geomorphologists to explain erosion patterns and other Earth-surface features.

Detachment Fault
A detachment fault is a gently dipping normal fault associated with large-scale extensional tectonics. Detachment faults often have very large displacements (tens of km) and juxtapose unmetamorphosed hanging walls against medium to high-grade metamorphic footwalls that are called metamorphic core complexes. They are thought to have formed as either initially low-angle structures or by the rotation of initially high-angle normal faults modified also by the isostatic effects of tectonic denudation. They may also be called denudation faults. Examples of detachment faulting include: *The Snake Range detachment system of the Basin and Range Province of western North America which was active during the Miocene *The Nordfjord-Sogn detachment of western Norway active during the Devonian Period *The Whipple detachment in southeastern California Detachment faults have been found on the sea floor close to divergent plate boundaries characterised by a limited supply of upwelling magma, ...

Tertiary Period
The Tertiary ( ) is an obsolete Period (geology), geologic period spanning 66 million to 2.6 or 1.8 million years ago. The period began with the extinction of the non-bird, avian dinosaurs in the Cretaceous–Paleogene extinction event, at the start of the Cenozoic, Cenozoic Era, and extended to the beginning of the Quaternary glaciation at the end of the Pliocene, Pliocene Epoch. The Tertiary has not been recognised by the International Commission on Stratigraphy (ICS) since the late 1980s, with the timespan of the Tertiary now being split in to the earlier Paleogene and the more recent Neogene periods, though the Tertiary continues to be used in some scientific publications. Historical use of the term The term Tertiary was first used by Giovanni Arduino (geologist), Giovanni Arduino during the mid-18th century. He classified geologic time into primitive (or primary), secondary, and tertiary periods based on observations of geology in Northern Italy. Later a fourth period, t ...

Erosion
Erosion is the action of surface processes (such as Surface runoff, water flow or wind) that removes soil, Rock (geology), rock, or dissolved material from one location on the Earth's crust#Crust, Earth's crust and then sediment transport, transports it to another location where it is deposit (geology), deposited. Erosion is distinct from weathering which involves no movement. Removal of rock or soil as clastic sediment is referred to as ''physical'' or ''mechanical'' erosion; this contrasts with ''chemical'' erosion, where soil or rock material is removed from an area by Solvation, dissolution. Eroded sediment or solutes may be transported just a few millimetres, or for thousands of kilometres. Agents of erosion include rainfall; bedrock wear in rivers; coastal erosion by the sea and Wind wave, waves; glacier, glacial Plucking (glaciation), plucking, Abrasion (geology), abrasion, and scour; areal flooding; Aeolian processes, wind abrasion; groundwater processes; and Mass wastin ...
