Bombshell Rocks

given an observation journal to record primary data about the two types of rocks, at Coomera (Nucrush Quarry) and at Springwood Conservation Park. To maintain an equal representation, secondary data will be used to refer to the main points. On our field trip, we went to Nucrush Quarry at Coomera. Nucrush offer a range of products that are all made from a sedimentary rock by the name of, Greywacke. Figure 1: The Rock Cycle According to figure 1, greywacke is formed deep under the sea. The…

The Badlands formed from a complex geologic setting. The topography that we see today is formed from erosion of the soft and not well-consolidated rocks. The oldest rocks found at The Badlands National Park are the Upper Cretaceous mudstones of the Pierre Shale (Graham, 2008). Overlying the Pierre Shale is the Fox Hills Formation, and overlying the Fox Hills Formation is the Tertiary White River Group. The White River Group contains a paleosol that are bright red. Overlying the Fox Hills…

leaves and the light grayish blue rocks, and the small touch of yellow flower on the right side of the photograph, the combination of the color adds drama and it gives balance to the whole picture. The texture of the rock from the picture looks…

type of shale rocks are chosen because they are “local” rocks which was abundant and available in the lab, also they have very similar mineralogical compositions. Both of the shale samples are provide by the SEER lab (Abiola). Before the tests, samples are cut into piece from the core with thickness about 1 in, and polished to make the top and bottom surfaces parallel. All tests are proceed on Nanovea Indenter perpendicular to the bedding direction. As natural material, the shale rock…

1. Short summary of the history At 145 ± 4 to 66 million years (Ma) ago, Cretaceous period was the last period of the Mesozoic Era, right after Jurassic period and followed by the Paleogene period of the Cenozoic Era (International Commission Chart, 2014). 'Creta' in Latin means chalk and this is due to the large amount of calcium carbonate deposited by shells of marine animals thus resulting in large quantities of chalk (American Geological Institute, 1972). The shifting of continents as the…

intruded country rock with different igneous compositions. These compositions ranged from alkaline to mafic to rhyolitic based on their interactions as they made their way to the surface with country rock. Mafic magma interacts well with host rock while rhyolitic magma does not due to its high viscosity.…

Gissella Fajardo Treasure of the Earth: Gems Nova The title of the documentary that we watched today was “Treasure of the Earth: Gems Nova”. The intended audience is anyone that is interested on learning about gems like rubies, diamonds and sapphires.The purpose of the documentary is to inform the audience about gemstones. I didn’t know specific information about gemstones. During the documentary I learned that near the Earth's surface many gemstones are formed when…

CMRJ341 Professor Jennifer Bourgeois October 18, 2015 Impact radial fracture lines ends shortly after the earlier impacts. In this case, bullet (C) was the first shot followed by (B) And lastly (A). In order to figure out the order of bullets is figuring out the radial fractures is looking at the initial fracture. Bullet fractures are round and has the same shape as a wheel. Fractures Also connects in the shape of a spider web. Then you have to figure out which side the fragment is facing in…

weather in the United States, which it can attribute to its geology. San Diego is also well known for consistent droughts; however, its current unique geography is a result of ancient rivers and seas depositing Cretaceous and Tertiary sedimentary rocks. As a result of these ancient rivers, “San Diego County can be divided between three distinct geomorphic regions: the Coastal Plain region as exposed west of the Peninsular Ranges, the Peninsular Range region, and the Salton Trough region as…

In 1965, the serpentine rock became California’s state rock; they are abundant in central and northern California. The serpentine rock is a metamorphic rock that forms by the hydration of rocks from the Earth’s mantle; these types of rocks will rise towards the Earth’s surface along fault zones. It can be found in various colors from dark green and brown, to blue with a glossy surface. However, these rocks tend to be slippery and creates a high risk for land slides. Through a series of…
