Metamorphic rock

extrusive igneous rocks (rhyolite to dacite), metamorphic rocks (quartzite) that have high T/P ratios, greywacke, and chert. The source of the clasts might be a continental crust. The Panoche Formation was part of the submarine fan that migrated laterally in the turbidite…

way through the crust, only to cool and become granite and pegmatites. This magma changed the existing rocks making schists and quartzite. After the inland sea receded erosion dominated the area eroding many layers of rock that had been deposited. A massive uplift rose these rocks to 15,000 feet. The erosion process eventually got rid of the sedimentary layers, exposing the granites and metamorphic knobs that we see today. Imagine if one of these processes did not take place. Would there even be…

understand the formation of the Himalayas. Some of these are the rocks collected…

fault; the St. Nicolas fault which brought the Manhattan schist. There were observations of boudins of quartz, which are kinetic indicators of movement and stress on the rocks (Flores, 2016). In the Manhattan schist basaltic intrusions were also observed and contact of the intrusion zone. The pegmatites, which are igneous rocks, observed pointed to the Acadian orogeny which followed the…

“Will look over here!” Miranda said as she looked out the window to an asteroid passing by. “Woah!” said Will as he saw the asteroid pass by with a loud whoosh! I thought the rocketship Fuzzball was going to crash because of the asteroid that passed by, Will nearly ran back to control Fuzzball. We have been on this rocketship together for almost 2 years! We are almost at the Ooblekian planet and we don’t know what to expect because all we have heard from our boss was that the planet Ooblekian is…

till. The sandstone was the oldest in the formation of rocks dating back over 550 million years. It was a layered set of sandstone and was folded. The elevation was less than 1,000 feet and its thickness was approximately 115. The next oldest in this area was the Ordovician dolomite. This is roughly 505 million years old. It was bedded flat and had layers. Its elevation was also less than 1,000 and the thickness was approximately 20. The newest rock in the area was the quaternary till that was…

During the Scottish Enlightenment, a period of increased intellectual activity in the 18th and early 19th century, individuals tended to explore multiple disciplines of study (Young, 2016). One prominent Scottish Enlightenment figure was James Hutton, living from 1726 to 1797. During his lifetime he was a lawyer, geologist, chemist, physician, farmer, and naturalist. Hutton, along with other prominent Enlightenment figures, Joseph Black and Adam Smith, founded the Oyster Club. This intellectual…

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…

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…
