Different Types Of Sedimentary Basins

Out wash has small sediments sorted in layers, and Till has large sediments not sorted into any layers. Till can leave behind features like Kame, Drumlins, and Moraines. Drumlins are elongated hills of till. Drumlins can be found in Central Minnesota and/or South of Brainerd. Moraines are very large ridges of Till. Moraines can be found in West/Central Minnesota. Outwash can leave features behind like Outwash Plains and Eskers. An Outwash plain formed by melt water of a glacier. Outwash plains are important because they are very great for farming which is a huge part of America. Glaciers can leave behind features like Kettle Lakes. Kettle Lakes formed by ice chunks falling off the main glacier, causing an indent on the earth's surface. Then the ice chunk will melt causing the hole to fill up with water. Most of Minnesota’s Kettle lakes are in Moraine/Terminal Moraine

The three faults being considered are thought to have influenced the character of some 120,000 square miles. The Big Pine, Garlock, and San Andreas faults are all mutually active, deep, long, and steep and noted as being conjugate shears. In concert, the faults have defined a primary strain pattern of relative east-west extension and north-south shortening of the area of 120,000 square miles. The large region is noted for its deformity, with the source of this being a northeast-southwest counterclockwise compressive couple. The compressive couple was potentially supported through drag as a result of the deep-seated movement of rock material from the Pacific region (Hill & Dibblee, 1953). The interaction of the faults in the San Andreas region since the Jurassic period have served to shape and contour the present geology of the land, while a study of the paleontology of the region likewise requires such knowledge to effectively determine conditions at any given point in time.

There are coarsening-upward sequences preserved, with flooding surfaces represented by low-relief erosional contact of trough-cross-stratification (runnel) upon low-angle planar bedding (swash zone).

The Lynne deposit lies within the early Proterozoic Penokean fold belt of the southern province of the Precambrian Shield. The fold belt is divided into two major terranes in Wisconsin (Sims 1989). The first is the northern Penokean terrane, which contains major oxide facies iron formations and granitic intrusions (DeMatties 1989). The second major terrane, separated from the Penokean terrane by the Niagara fault zone, is the Wisconsin magmatic terrane, characterized by a volcanic island arc-basin assemblage (Sims 1989). This southern terrane lacks major oxide facies iron formations, but contains abundant tonalite-granite intrusions (DeMatties 1989). The Wisconsin magmatic terrane is further subdivided into the northern Pembine-Wausau terrane and the southern Marshfield terrane, which are separated by the Eau Pleine shear zone, a north-dipping subduction zone (Sims 1989).

When the Ouachita Mountains were created, the sediment carried by rivers was sent downward and eroded again. Swamps overfilled with clay and plant remains ended up buried. These remains become valuable products of the valley today- coal and natural gas. This region varies between narrow ridges and flat-topped mountains with rolling or hilly plains split by the river. The Arkansas River was an important means of transportation between the mountains. Present day Batesville, Fort Smith, Clarksville, Russellville, Morrilton, and part of Conway are within this

Rodinia started to rift around 750 to 600 million years ago and the Iapetus Ocean opening up as seen in Figure 1, the Swift Run Formation with Grenville, volcanic debris and ash material produced the Catoctin Formation that contains flood basalts supporting Shenandoah. With modern day East Africa rift and Red Sea curst stretched, this allowed flood basalts and rhyolite seep through the ocean floor and eventually made its way to the surface.

First, we must examine the sedimentary formations; when they were formed, how they were formed, and what materials they consist of. About ninety-three to one hundred million years ago, the Western Interior Seaway rolled through the North American continent, eventually reaching the geographical area of today’s Mesa Verde National Park (National Park Service 2005). This sea deposited a thick, hard sandstone base that is called Dakota Sandstone, although this layer is not exposed in the park

Below these Carboniferous rocks, Devonian rocks are also exposed. These rocks can be found along the northern edge and southeastern margin of the plateau, where strata is nearly vertical. These two geologic systems have also been subdivided into numerous formations categorized according to their lithologic aspect and the fossil fauna and flora which they

It consists of the state’s most unique landscapes – strangely long, tapered and almost parallel ridges and valleys, all mingling over water gap formations. The province extends from the center towards New Jersey (north-eastward) and into Maryland (south-westward). The province’s ridges and valleys are made up of Sedimentary rocks from the Paleozoic Era. Metamorphosed Proterozoic volcanic rock (~575 million years old) is also found in some ridges of the South Mountain sector of the province. The sediments were originally deposited in a horizontal manner, but then these rocks were subjected to a high amount of heat and pressure during the Alleghanian orogeny, which resulted in them being folded and angular. The erosion of sediments over the years have formed a very distinct landform – valleys have been formed over areas of shale and limestone (softer rocks) and ridges have been formed in the areas of sandstone (harder rock). This Province is divided into 7 sectors: South Mountain, Great Valley, Blue Mountain, Anthracite Upland, Anthracite Valley, Susquehanna Lowland and Appalachian

The first deformation event (D1) resulted in folding of volcanic rocks in the Wabigoon and Wawa subprovinces (Hooper and Ojakangas, 1971; Hudleston, 1976; Hudleston et al., 1987; Jirsa et al., 1992) and locally within the Quetico subprovince (Bauer, 1985b). Most D1 folds in the Wawa terrane in MN rarely display axial-planar cleavage, with Bauer (1985b), Hooper and Ojakangas (1971), Hudleston (1976), and Jirsa et al. (1992) having identified cleavage (S1) development locally in the Vermillion greenstone belt (Peterson, 2001). In the Wabigoon terrane, D1 resulted in recumbent folding that overturned the stratigraphic sequence and the first regional schistosity (Poulsen et al., 1980). S1 is generally subparallel to the layering in the metavolcanic and metasedimentary rocks, and a gneissic foliation attributed to D1 is well developed in gneissic domes (Czeck and Poulsen, 2010). Although D1 likely created significant thrust or oblique faulting, direct evidence

This formation is a very fine grain Mississippian limestone. To test to see if this was the Bangor formation we used HCL and because there was a reaction we know its limestone. This formation could also be described as gray in color as well as an average thickness of 700 feet. We see the Bangor until stop eight, where we see a very different vertical bedding. Also different at stop eight is the outcrop no longer reacts with HCL. From this we gathered that we had moved into the Hartselle formation. In the Hartselle Formation, Mississippian aged sandstones are dominant. This particular stop had a large amount of jointing. After the Hartselle, we figured the Pride Mountain Formation would be next, however at stop nine we see the Maury Formation present. This stop focused on the rock located inside the creek. Because we were unable to go into the creek to get the strike and dips, we once again had to do a projected orientation. Also found on this stop were natural sulfur springs, easy to notice with the smell that it gives off. The Maury formation consist of Mississippian- Silurian aged shale. At the next stop, stop 10, we encounter the Ft. Payne formation. Although this area location was thickly vegetated, we were able to conduct the acid test and saw that the HCL reacts in some places but not all. From this we concluded that this was the cherty limestone of the Ft. Payne formation. The following stop, 12, we went up section and arrived at the Maury Formation once again. At the final stop, location 13, we see Ft. Payne Formation. All of the metamorphism and deformation in the southernmost Appalachians can be related to the movement of the thrust sheets and stacks (Higgins,

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

According to the geological definition, the Gulf of Mexico is an ocean basin bounded on the northeast, north, and northwest by the Gulf Coast of the United States, on the southwest and south by Mexico, and on the southeast by Cuba. The formation of Gulf of Mexico can be dated back to the late Triassic, which was about 300 million years ago. The ancient mega-continent Pangea was split by a 6,000 km long crack into two supercontinents--Laurentia and Gondwana [2], which are mostly the North America and the South America with Africa. During the extension and stretching of the super-continents Laurentia and Gondwana, there was a great rift basin being formed across South

The Plains take second place! This region was created when soils by rivers and lakes from the Canadian Shield were deposited at this regions edge. In addition, sedimentary rock was formed from these deposits, which became huge areas of flat, fertile lands, river valleys, and rolling hills. To add, there are three flat levels and each consists of hills, cliffs, low mountains, forests, wide river valleys, and sand

Stratigraphy: The Augustine-Seldovia arch, which is oriented east-west, transverse to the main structural trend of the basin, separates the forearc basin into two depocenters. (ADNR 2006). The northern depocenter in upper Cook Inlet is dominated by roughly 25,000 feet of Cenezoic strata. The southern depocenter in lower Cook Inlet and Shelikof Strait contains a thinner Cenezoic section superimposed on top of 36,000 feet of Mesozoic strata.
