Dolomite

supersaturated in dolomite, yet dolomite is rarely directly precipitated in the present day. Discuss the strengths and weaknesses of different mechanisms that have been postulated to explain dolomitization, and why it is important to understand from a hydrocarbon perspective. Introduction Dolomite (CaMg〖(CO_3)〗_2) is found in carbonate rocks of all ages that formed under a variety of conditions, but today it only forms in hypersaline lagoons, lakes and tidal flats. This suggests that most dolomite is secondary

The studied sedimentary succession are characterized by their on-lapping nature on top of Yellow Limestone Group, which is presented by impure limestone occurrences in Jamaica. By using chronostratigraphic constrains derived from 87Sr/86Sr values, biostratigraphic information and sedimentologic and stratigraphic characteristics of these successions, we propose a sequence stratigraphic framework for the Eocene-Miocene carbonate deposits in Jamaica. Figure xxx show the sequence stratigraphic framework

The term Keg River has been historically used within Alberta to indentify early to middle Devonian carbonate reef type structures within the Alberta Basin. Nomenclature problems were identified by Schneider (2011) with commonly interchangeable terminology that began in the 1930s, including Upper Elk Point formations such as the Winnipegosis, Keg River and Methy. Sproule (in Ells, 1932) described the Keg River from outcrops along the Clearwater River, near Fort McMurray in the 1930s. Sproule described

ranging up to 9,753ft. In Switzerland there is a mountain called Weisshorn. This mountain has a major peak with an culminating at 4,506 above sea level and its elevation is 14,783ft. One more mountain I would go see is iin Northwestern Italy called Dolomites. This mountain forms a part of the Southern Limestone Alps (or a high mountain, especially a snow capped one) and it extends from the River Adige in the west to the Piave Valley in the east and this mountain's elevation is 10,968ft.Europe also has

the example of dolomite in order to show that human interests do not play a role in science. His belief is that there is nothing less socially constructed than a rock, but this statement does not accurately portray the facts. Dolomite has a long history that involves a number of people and social interests. Each person contributed to the discovery and identification of dolomite and social factors were at play during the scientific process. Hackling starts with the history of dolomite. In 1791, a French

Cape Lieper and Cape Ingersoll formations: They are part of Ryder Gletscher Group. They are mainly composed of dolomites and other carbonates rocks and they overlie Dallas Bugt Formation with thicknesses of up to 40m (Higgins et al, 1991). Other smaller formations within the Ryder Gletscher Group include Lower-Middle Cambrian wulff River and Cape Wood formations and they are mainly dominated by irregular bedded micritic limestone with thickness of up to 150m (Higgins et al, 1991). Cape Kent Formation

upper members), Mule Spring Limestone, Monola Formation (lower and upper members), and the Bonanaza King dolomite (dominantly limestone and undivided). These Cambrian rocks are followed by rock layers from the Devonian period, thus meaning that an unconformity occurred between the layers. The Devonian dolomite rock layers include the Hidden Valley dolomite and the Lost Burro Formation (cherty dolomite). These are followed by the Mississippian

1. The depositional environments of the six facies displayed in Figure 1 are as follows: • Fore reef (dark blue)-The mudstones indicate a low energy environment and small amounts of skeletal fragments creating a wackestone, suggesting an infrequent presence of organisms. The conglomerates have formed due to gravity driven flows. • Reef crest (orange) - Indicated by the presence of red algae and Schleractinian corals e.g. .Acropora (Oppen, at el, 2000), which suggests a low energy crest. • Lagoon

Even though, it share similarity to the other region in the Western Northern America province, what make Death Valley unique is the characters of the mountains and desert valleys are in a grand scale than the others. In addition, varies rock type and formation which include volcanic, metamorphic, and sedimentary rocks makes the valley a great place for geological study (Green, 1997, p. 9). Today’s Death Valley we see has taken millions of years to take its present form. In this paper, we examining

With the presidential elections coming up, the issue of health care coverage will definitely be a hot issue for debate. The people behind the website called Barack Obama created a webpage specifically for detailing how President Barack Obama will be a better candidate for what happens to health care. There are three videos on the webpage that show people who have been affected by the president’s Affordable Care Act. In these videos aimed towards the voters of America, Barack Obama frames those who
