Granite Granite is a volcanic igneous rock that is formed by the slow cooling of magma. While it is a suitable stone to build structures, nowadays granite is used almost only used as an interior or exterior covering. Advantages offered by granite are that it is stain resistant, it is a sanitary (Non-Porous) surface, it is heat resistant, and in general, it is abrasion resistant. That said, while this material is very hard and crystalline in nature, some granites are resin-treated to enhance the color. For this reason, many types of granite have lower abrasion resistance than expected. Limestone Limestone is a sedimentary rock composed essentially of calcite, a mineral of calcium carbonate. The formation processes of limestone differ substantially in the origin of the constituents sediments: these may result (organogenic limestones) from shells or exoskeletons. They can also be formed by the chemical precipitation of salts dissolved in water (chemogenic limestones). Finally they may come from the degradation of existing limestone (detrital or clastic…

Ian Miller is a Paleontologist who works for the Denver Museum of Nature and Science. Ian Miller’s problem is that he wants to find out how Western North America changed from the past 100 million years, what past climates were like 100 million years ago and the fossil ecosystems that existed 100 million years ago. Through solving and studying this problem, there have been many obstacles to solving his questions. Although obstacles causes trouble and hardships through experiments and test, Ian…

Marble is a metamorphic rock that can be found in lots of places, this rock has many uses in our everyday life. This rock can be found in many common household items. There are many different colors of marble that are found all over the world. Colorful marble is discolored due to how it was formed. When marble is formed from a limestone that has few impurities, the marble turns white. If the marble contains clay minerals, iron oxides, or bituminous minerals, the marble will turn a different…

Purpose What makes the best bubble solution? In order to make a best bubble solution, I have to use detergent, corn syrup, water, and glycerin. By the best, I mean a mixture that creates a solution which will last long. Acknowledgments I would like to thank everyone who helped me make my project successful. First of all, I would like to thank my teacher Mr. Mackey’s help. He provided the instructions and explained how to do an essay and a poster board. Secondly, I would like to thank you my…

Caesar Stone was founded by Amos Amir, Gili Amir's father and CEO of Caesaria Marble, Sdot Yam's floor tiles plant, in the 1970s. Amir had come to the conclusion that the days of Terrazzo flooring, had passed. So he began searching for the next generation of flooring material that was thinner, lighter, and stronger, while being less labour intensive and polluting to produce. …??? Caesar stone is a stone manufactured to create surfaces such as benchtops, splashbacks, bathroom vanities, wall…

A lot of planktonic organisms use calcium carbonate to build their shells (Davis, 2017). If the foraminifera are in good health they will calcify probably and sink when they die. The shells from foraminifera clump together with coccoliths shells. These shells contribute to the ‘alkalinity pump’. The ‘ alkalinity pump’ transports carbon out of the ocean (Davis, 2017). The shells from foraminifera and coccoliths comprise 20-80% of marine calcite (Davis, 2017). The shell material also acts as a…

Abbylyn Sessions Professor Livingston Geology 1100 28 August 2016 Fantasy Field Trip Just outside of Custer, South Dakota is a hidden geological treasure: Jewel Cave. Jewel Cave has over 181.89 miles in mapped passageways making it the third longest cave in the world (United States. National Park Service). The formation is lined with calcite crystals creating a beautiful view inside. Jewel cave is a geologic wonder that would make a great field trip. A field trip to Jewel cave would allow the…

Questions and Answers Rock specimen “A” is identified as marble. This sample had a white to cream color to it, which is an identifying characteristic of marble. Another characteristic is the calcite inclusion; this inclusion is seen by bubbling when exposed to a saturated citric acid solution. When viewed by the unaided eye, the grain and crystal structure is clearly seen. While marble is supposed to be a fairly soft rock, the example provided proved to be fairly durable which was tested…

impact of short-term exchange on geochemical proxies. Foraminiferal calcite is the foundation of many proxy-based reconstruction. Hence, understanding the mechanism of exchange and determination of rate of mineral-fluid exchange in foraminiferal calcite are critical for accurate estimation of the extent of post-formational alterations on carbonate-based proxies. The reaction rates estimated in most of the atom exchange experiments are under the basic assumption of homogeneous exchange at…

preferred methods used for deep time isotopes. As the calcite within the hard shell of a brachiopod precipitates out of the surrounding seawater, trace elements are recorded within the shell, indicative of information detailing the surrounding water. Most species of brachiopod shells are composed of a low-magnesium calcite, one of the most stable forms of skeletal carbonate; much less prone to diagenesis than other species. These shells are then…
