The Structure Of A Basin

Approximately 17 meters thick, Unit A defines the lowest third of the Juniata Formation. Fragments of marine fossils, including bryozoans, brachiopods, and gastropods, are commonly found in the bottom-most portion of this unit of structureless mudstone and quartz arenite. Quartz grains in the sandstone beds of Unit A are typically immature and fine-grained, though the sandstone packages tend to coarsen upwards. Though typically structureless, intermittent bedding of the sandstone and shale packages is observed in this unit, and some areas display

Starved Rock State covers about 200 miles and some 470 million years, from Ordovician sandstones to Pleistocene glacial till. The Ordovician St. Peter Formation sandstone was deposited across the midcontinent during the second major marine transgression of the Paleozoic Era. The first transgression deposited Upper Cambrian to Lower Ordovician clastics and carbonates. The clastic to carbonate rock transition is consistent with gradual sea level rise over the North American craton. Sea level dropped late in the early Ordovician, exposing the carbonate strata to processes of cave development.

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

The Copper Basin of southeastern Tennessee is an area that is climatically unique with a rich history rooted in copper mining. It is thought that man is responsible for the total destruction of the environment over this large area, but it is mostly contributed to the exclusive location. The Copper Basin was susceptible to negative environmental effects due to its topographical, geological, climatic, edaphic, and meteorological location. However, the copper mining had a transformative effect on the surrounding lands that of which are still recovering.

The Earth's crust has been undergoing complex chemical, physical, and biological reactions over more than 4 billion years now. In this relentless tardiness of geologic instance, the convection of the Earth's mantle gave form to the planet (Cronon, 1993). The Middle Atlantic region of North American was shaped by the tectonic plate movements and climatic changes shaping the ancient oceans into lands. Water streams gave form to hills and deep valleys and rainwater broke big rocks into fine soil. It is interesting to note that while all this was taking place, Maryland's mountains were comparable to the size of the Himalayas (Flannery, 2001). Their rock gradually created the mountain that we see in Maryland in the present day. Eventually, Maryland's rock layer turned into fertile soils, mineral deposits, and composite water elements.

The quadrangle is considered to be a part of the Allegheny Plateau, so the rocks in this region are mostly of Carboniferous age. Carboniferous rocks are subdivided into two series: the Pennsylvanian and Mississippian. The rocks of both series mainly consist of alternating beds of shale and sandstone, but Mississippian rocks on southern parts of the plateau include thick limestones (Phalen 1). Both series are represented in the Johnstown quadrangle. The Pennsylvanian series, however, covers most of the region, while Mississippian rocks appear only at the surface along deeply eroded anticlines.

The Ukiah Valley Groundwater Basin is comprised of seven water entities that supply water to the region which includes the City of Ukiah, four water districts, Rogina Water Co., and the Russian River Flood Control and Water Conservation Improvement District. The following is a description of each water entity that is responsible for providing the necessary water supplies for meeting majority of the municipal and agricultural water demands in the region.

At both Cienega Amarilla and Cottonwood Canyon, stratum VI consists of a 0.2–1.3-m-thick surface layer of bedded, fluvial sand locally with a very weak soil profile (Figures 3 and 4; Table 3). No radiocarbon dates or plant macrofossils are associated with stratum VI, but radiocarbon dating of underlying stratum V alluvium indicates that stratum VI post-dates ~300 cal BP. Stratum VI alluvium appears to represent arroyo fan deposits associated with historic period arroyo cutting. Accounts from ranchers indicate that arroyo-cutting in this area occurred in the late 1800s or early 1900s, consistent with widespread arroyo formation across the southwest U.S. at this time (Waters and Haynes, 2001).

The Arkoma Basin is one of several foreland basins that formed along the Ouachita Orogenic Belt during the Mississippian and Pennsylvanian time periods. It covers approximately 33,800 square miles and extends from southeastern Oklahoma to central Arkansas (Perry, 1997). The Arkoma Basin is bounded to the north by the Ozark Uplift, to the south by the Ouachita Mountains, to the northwest by the Anadarko Basin, to the southwest by the Arbuckle Uplift, and to the southeast by the Mississippian Embayment (Figure 5). The red box in figure 5 denotes the general location of the study area, which is in the eastern Arkoma section.

The purpose of this assessment is to understand all topographic factors concerning the past, present, and future of Taylor Mountain Regional Park. The site is 4 acres in size and is located in Taylor Mountain Regional Park and Open Space Preserve. The coordinates of the site, according to the USGS 1954 Santa Rosa Quadrangle Map, are N 38 degrees 24 minutes and 30 seconds, W 122 degrees 41 minutes and 25 seconds (Figure 2). The entrance to the site is located at the 1900 section of Kawana Terrace, adjacent to the private continuation of Kawana Terrace in  Santa Rosa California 95407 in the United States. The site is located in the NE 1/2 of the SE 1/4 of section 36, T7N, R8W on the Mount

The Peninsular terrane is a Triassic to Jurassic island-arc complex that was accreted to the North American craton by the Early Cretaceous (Detterman and Reed, 1980; Jones et al., 1987; Ridgway et al., 2002; Trop et al., 2002, 2005; Clift et al., 2005). The terrane includes mafic to andesitic flows and volcaniclastic rocks, limestone, and mudstone. These rocks structurally overlie and are intruded by Jurassic plutonic rocks of the Talkeetna arc (Reed and Lanphere, 1973; Reed et al., 1983; Rioux et al., 2010). The plutonic rocks include gabbroic to granitic compositions, but are dominated by quartz diorite and tonalite rocks (Detterman and Reed, 1980; Reed et al., 1983).
