Methods of dating Basaltic rocks

- Basalt is a common extrusive igneous rock, there are a large number of volcanic provinces across Southeast Australia that have been found to contain basaltic lava flows. It is likely that these flows have come from volcanic activity caused by mantle plumes from the mesosphere. A variety of dating methods have been used to date these basaltic rocks, which have been aged from the Jurassic era right up to the late Cenozoic. 1. Composition of Basalt Basalt is a commonly occurring igneous rock. More specifically however, Basalt falls under the category of Mafic Rocks....   [tags: mafic rocks, volcanoes ]

The Coquina Rock: Diagenesis, and Sedimentary Rocks

- Type of Rock The rock coquina is originally a sedimentary rock. Sedimentary rocks are made up of sediments. The sediments are formed by the mechanical or chemical activities of the natural activities like running water, blowing wind, glaciers etc. this which causes disintegration and decomposition of the pre-existing rocks. The products of decay are transported to some depositional sites by the natural agencies, where they get deposited and with subsequent compaction form sedimentary rocks (Hefferan, O’Brien, 2010)....   [tags: sedimentary rocks, uses, myths]

Identifying the Distinct Rocks Types in the Streambed of Muddy Run

- Rivers and streams are the main transporters of sediment and rock and they are known for their powerful erosional capabilities. Sediment and rock travel down gradient from location to location until they come to rest in a delta or they are deposited when the velocity of the water has become too slow to move the debris any further. Secondary streams, although known for moving less sediment or rock, still retain the power to erode and transport. Muddy Run, a secondary bedrock stream in Oneida Township, Huntingdon County, Pennsylvania, is one such example....   [tags: Sediment and rocks, geological formation]

The Science of Rocks

- ... According to Thompson & Turk (2011), basalt, also commonly known as a mafic rock due to its high levels of magnesium and iron, contains olivine, pyroxene, and Calcium- and sodium-feldspar (37). Granite, on the other hand, is considered a felsic rock due to its high levels of potassium feldspar and quartz, and it not only contains the two mentioned minerals, but also often contains small amounts of biotite, muscovite, or hornblende which give it a speckled appearance. The difference in the mineral composition is apparent in the rocks’ color and grain texture....   [tags: lab exercise in geology]

Leonardo 's The Virgin Of The Rocks

- Foreshortening was another technique, closely tied with perspective, that helped to show the perceived depth of objects. Based on a similar principle, foreshortening is the visual shortening of objects viewed at an angle. For example, in the piece, The Lamentation of Christ, by Andrea Mantegna we see the posthumous body of Jesus lain on a table, with mourning followers off to the side. As the viewer is situationally placed at the feel of Christ, the length of his body is inversely stretched, visually speaking, which when viewed as a flat image, makes him shorter at this angle....   [tags: Leonardo da Vinci, Renaissance, Painting]

Over millions of years the layers of sediment build up resulting in the weight pressing downwards, creating high pressure, which squeezes the water out. As the water is squeezed out, salts form between the particles of sediment due to crystallization and this cements the particles together.

These rocks are from the early Proterozoic crust and act as base for younger Proterozoic rocks. Unfortunately other than the age of the rocks which make up the base, not much is known about them due to the environment altering that took place over time (“Geology”). However the rocks from the Proterozoic period that lay atop the base make up the basement for most of Death Valley....   [tags: Igneous rock, Sedimentary rock]

It is important to understand that in all of these events the molten magma was allowed to completely cool before the next event allowing for the formation of the iconic hexagonal columns of basalt (Puffer, 2009)....   [tags: Palisades Basalt]

Sometime between 1.8 and 1.7 billion years ago, the volcanic and sedimentary rocks were severely altered when chemical or structural changes occurred because of intense heat or pressure from the Earth's core.

There is some debate on whether basalt or schist was the original and dominate rock in the region before it was transformed into contorted gneiss, but again, there is no way to prove either theory....   [tags: elevation, dry, volcano]

Geology's Control of the Coastal Features in the Swanage Area

- Geology's Control of the Coastal Features in the Swanage Area Geology can have a great affect on many coastal features. This is because the lithology or structure of the rocks may affect the coastal landforms, and the different processes occurring may also affect the way the landforms turn out. Starting with the Swanage area it can be seen that the area of Swanage is an Atlantic coast. This means that there are bands of hard and soft rock in the coast and therefore due to rocks of different hardness, the rocks erode at different rates and so you get distinct landforms....   [tags: Papers]

- 1. Introduction Marie Byrd Land (MBL) is a massif within West Antarctica that is of critical importance in understanding the evolution of the West Antarctic Rift System (WARS). Although the WARS is comparable in size other rift systems, it is poorly understood due to extensive ice cover (LeMasurier, 2008). MBL contains exposures which inform on the behavior of the WARS over time (Cande et al., 2000; Steinberger et al., 2004) and the potential for subglacial volcanism associated with the system to destabilize the West Antarctic ice sheet, thus causing an instantaneous rise in sea level (Blankenship et al, 1993)....   [tags: West Antarctic Rift System, tectonics]
