Igneous rock

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…

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…

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…

1. Introduction Silicified wood is normally formed close to the surface due to the infiltration of buried wood with mineral-rich water and the associated deposition of minerals (Kim et al., 2009). Two typical geological environments have been reported, 1) trees transported by streams and rivers then buried in the fluvial sediments (e.g., Weibel, 1996; Fielding and Alexander, 2001; Parrish and Falcon-Lang, 2007; Hartmann et al., 2010), and 2) ash from volcanic eruptions buries trees while felled…

meter stick, rock hammer, flashlight, bottle of acid, and helmet, we set off to the mine. Located roughly 100 feet below the surface near Grand Rapids, the mine is now a storage facility owned by Michigan Natural Storage. In the mine, we measured the various rock columns to find how large the different sections of gypsum, shale and dolomite were. In addition to measuring the rock types, we took samples using the hammer. After the trip in lab the next week, we looked at the different rock types…

There are many land formations and I chose these three. The first one is a canyon, it’s located in Arizona and its name is Grand Canyon. The second one is a volcano it’s found in Washington State, Cascade Range and it is named Mount St. Helens. The last one is a plateau and it can be found in central Asia and it is called Tibetan Plateau. And then I’ll be comparing the different land forms. The Grand Canyon is in Northern Arizona with an elevation of 8,000 feet. The process of the…

exposed rock material has a visible reverse fault, and is heavy faulted/folded. Visible soil, and vegetation growth on exposed section of the formation. Visible iron oxide staining from fractures in the section both natural, and manmade. Alternating material layers light grey to dark grey in the formation, and thick bands. 0 to 3feet of the section is composed of light grey, and soft material. The bottom facie was a small section of laminated layered shale. 3 feet to 6 feet of the exposed rock…
