Analysis On The Nubian Sandstone Aquifer System

The Nile has been one of the most important resources throughout human history. After the river floods, it provides very rich soil great for farming. After learning the flood

Sandstone Federal Correctional Institution in Sandstone, Minnesota has housed many an inmate including the actor Tim Allen (Rodriguez) and it ranks 40 of 50 on arrestrecords.com’s 50 most comfortable prions in the world. A well-maintained lawns leads to well-kept cells, where nonviolent offenders are kept occupied with leather making and stained glass creation. Some inmates may consider this a little boring, but anything is better than being assaulted. (Records) This paper will discuss the history and current dynamic of Sandstone, inmate demographics, services available to them, staff demographics and their style of this staff.

In document B it says that in the flood season the Nile River fertilized the ground. The fertile ground made it great for crops and, as discussed in class, 95% of Egypts population were farmers. Also in Document B, it shows Egyptians made their seasons around the flooding of the Nile instead of the temperature. When the Nile flooded, it left fertile soil for crops. When it receded, it receded just enough to still fill the irrigation canals to carry water to the crops.

One of the major things noticeable from the cross section is that quite a few of the rock layers are over turned, where the older rock layers are above the newer rock layers. This is seen in the contact between the Quartz Monzonite of Papoose Flat and the Campito Formation which is also a disconformity. Next there is some fault zones separating the Camptio, Poleta, and Harkless formations. We then see some more overturned layers with the contacts between Saline Spring Valley Formation (lower and upper members) above the Mule Spring Formation along with some inferred folding. With a normal fault separating the inferred folding event, we see where the overturning occurs. In between the Cambrian layers we see Tertiary Basalt nonconformities also being folded, thus with that we know that the folding event was more recent than the formation of the Basalt. Next there is a large Basalt field with a spot of the Harkless formation. Again we see over tuning as the Basalt field ends there are the Devonian and Mississippian rock Layers on top of the basalt. Separating these overturned layers from the Harkless Formation and the Saline valley Formation (upper member), which are not overturned, is a thrust fault. From this information, there was a major stress event sometime after the Tertiary period causing the rock layers to fold and overturn. And from this stress event and from the folding, normal and thrust faults are formed. Finally we see that there were alluvial and landslide deposits from the Quaternary after the folding, faulting, and over

Weathering, geologic processes such as erosion, and climatic shifts allow for this immense desert ecosystem to continually evolve and change which has taken place for millions of years. This geologically wealthy environment is composed of alternating flat-lying layers of soft and hard deposits of mostly sedimentary rocks. Interchanging slopes and cliffs along the landscape helped form these layers of rock which can be seen fully exposed in areas of the mesa. Deposition of this landscape mainly occurred during the Permian, Pennsylvanian, Triassic and Jurassic time periods. The assortment of warm hues of sandstone were produced by varying levels of iron oxide minerals during formation.

During the late Holocene, the Cienega Amarilla and nearby Cottonwood Canyon floodplains underwent dramatic geomorphic changes, experiencing periods of rapid high-energy deposition, slow low-energy deposition, stability and soil formation, and deep channel entrenchment and subsequent infilling. Many of these shifts likely represent geomorphic responses of hillslope and valley subsystems to climate change and variability. Cienega Amarilla became a groundwater discharge dominated system from ~2.3–1.6 ka, and then transitioned back to a runoff-dominated system by ~1 ka. In this section, I examine possible linkages between these hydrological and geomorphic changes and paleoclimatic variation.

The western Cordilleran orogenic belt had been depicted as a passive margin after Neoproterozoic to Early Cambrian rifting. Afterwards, the passive margin converted to an active margin most probably about Late Devonian to Late Cretaceous through the subduction of the exotic allochthons beneath the North American plate. The late Jurassic to Cretaceous subduction of (Sevier and Laramide Orogeny) representing as a period of the back thrust, intraplate thrusting, behind a magmatic arc on the upper plate near or on its westernmost margin from the latest

Across history the River Nile has captivated philosophers, geographers, historians, engineers, politicians since the humans set their eyes on its water. A great civilization had been flourished along the Nile banks, the Pharaonic civilization. Herodotus, described Egypt as “an acquired country, a gift of the River Nile” [1]. The River Nile is considered the second longest river in the world. It has a length of about 6,500 km which extends from the most remote source, at the head if the river Luvironza (near Lake Tanganyika), to its mouth on the Mediterranean Sea. The Nile basin in its present situation covers a drainage area of about 3.11x106 km2. The basin extends from 4°S to 31°N latitude and from 21° 30’E to 40° 30’E longitude. The highest

The Edwards-Trinity Aquifer is one of Texas’ major aquifers, located in west central Texas and spanning near 42,000 square miles as shown in figure 1 (Barker and Ardis 1996, 2). The aquifer encompasses 36 counties including major counties such as Crockett, Edwards and Val Verde as shown in figure 2 (Hopkins 1995, 2). The population is relatively sparse, with most of the population located in small cities Anaya 2001, 100). It is divided into four subareas based on the topography of each area, Edwards plateau, Trans-Pecos, Hill Country and Balcones fault zone (Barker and Ardis 1996, 5). Edwards plateau has two types of terrain, the interior of the plateau is fairly flat with a gradual slope, and the outer portions are more rugged with canyons

The basement rocks in the western Slave carton is older than 2.8 Ga and the known oldest rocks are the genesis found along the Acasta River which is about 3.6- 4.0 Ga old, which is estimated using the zircon dating (Isachsen & Bowring, 1994; Padgham,1992). Following by 2.8 - 3.5-Ga old genesis of Point Lake and genesis under the Yellowknife Greenstone belts, which exist over 3 Ga (Isachsen & Bowring, 1994; Padgham,1992). The major rock types include granitic to tonalitic genesis, migmatitic genesis and granodiorites, which have been deformed and metamorphosed (Fyson & Helmstaedt, 1988; Isachsen & Bowring, 1994; Padgham,1992). In the eastern Slave Craton, the basement is not confined but is correlated to the Nd-Pb isotopic boundaries

Two-hundred million years ago a salt sea covered the Permian Basin which can be attributed to the abundance of oil in Odessa, Texas. Once the structure of the Earth changed a limestone floor developed in the sea. With the help of other rocks, hydrocarbons were trapped from the plants and animals which later resulted in the formation of oil and gas. This area is known as the Permian Basin and distinguishes counties in West Texas and South New Mexico. The Permian Basin earned its name with Permian referring to the Permian Period where sedimentary beds were simultaneously deposited in parts of Russia, England, Southeast New Mexico and West Texas. Basin can be defined as, geologically, a natural indentation in the Earth’s surface that contains water. Two thousand foot cliffs of limestone that cover West Texas and South East New Mexico were at one time submerged reefs created by millions of lime-secreting algae. With this knowledge the West Texas Geological Society

The South Brae oilfield is mainly Kimmeridgian to mid-Volgian in age, however on some accounts it may possibly be of Oxfordian (Turner et al, 1987). The oilfield is heavily developed along the western, fault-bounded margin of the South Viking Graben approximately 161 miles NE of Aberdeen flanking Fladen Ground Spur (see Fig.1). The Upper Jurassic rifting of the South Viking Graben encountered, pronounced movement along the western bounding fault as syn-rift extension proceeded (Harris & Fowler, 1987, Gregory et al, 2007). Syn‐tectonic deposition throughout the Jurassic ensued the formation of a distinct sediment wedge thinning eastwards into the basin, outlining the main phase of fault movement down the boundary fault (Roberts, 1991). As a result, the Brae oilfields are a series of

An aquifer is a permeable rock underground that bears water, this water can be collected through wells for people to use and drink. Within Texas there are 23 different aquifers, but for Central Texas we tend to favor Edwards Aquifer and due to this many problems have arisen for the aquifer and its inhabitants. We will first discuss the history of Edwards Aquifer, the reasons behind the current issue concerning the aquifer including what species are endangered and why, and lastly what solutions are being set forth.

an event similar to the 365 AD event may occur about every 800 years, with the lastEgypt is situated on the northeastern side of the African continent and bordered by the Mediterranean Sea from the north with coast line of about 995 km long. The Egyptian Mediterranean coastal zones is one of the tsunami prone areas in northern Africa and affected by very strong tsunamigenic earthquakes in the historic (past) which have occurred in the eastern Mediterranean region along two subduction zones; Hellenic and Cyprian arcs. For instance, the most severe events that happened along Hellenic arc were 21 July, 365 AD and 8 August 1303 AD. These tsunami events caused widespread damages and destroyed the Nile Delta region, northern part of Egypt (Sitros

Ultra-high pressure metamorphism (UHPM) refers to a process of extensive subduction continued through continental collision. The complexity of these rocks occurrence at the surface leads to questions about exhumation, potential depths, and rates of these
