Igneous rock

about 30 minutes until he began to talk about the Rock Garden. Chad: “After Founders Hall, please head to the Rock Garden, where you can show your students our 19 large rock specimens ranging from 100lbs to nearly 1 ton. In addition, to our 5 sedimentary, 6 metamorphic, and 7 igneous rock types.” Me: I immediately raised my hand and said, “I am so sorry to interrupt, but that is just fascinating. Unfortunately, I haven 't been able to visit our Rock Garden. I hope I am not only speaking for…

that will work to find the age for that fossil. As well as the many terms that goes in the processes for dating fossils. Relative dating does not give an actual date for the fossils. Relative dating is used to organize geological events, and the rocks they leave behind in a sequence. A geological event is basically a severe natural event that happens in the crust of earth that is normally harmful like an earthquake or a volcano . The method of reading the order is called stratigraphy…

be used to represent the sedimentary rock. The goal is to see if different amounts of alum powder will affect the amount of crystals that grow. In this experiment, the groups’ hypothesis is the more alum powder in the solution, the bigger crystals will form. A geode is a “mass of minerals within a rock that can take thousands of years to form” (Steve Spangler). The word geode is from the word Geoides, which is considered “Earthlike” (Wonderopolis). These rocks form geodes when…

Hill pluton of South Carolina is one of twenty-four known granitoid bodies along the southern Appalachian Piedmont which possess the properties of a supergroup as described by Pitcher. The country rocks surrounding the plutons are at least mid-Paleozoic in age. Liberty Hill lies within country rocks of the Carolina Slate belt which consists of “primarily intermediate to felsic pyroclastic debris and hypabyssal intrusive bodies.” (Speer et al. 1980). The isotopic ages of metamorphism from 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…

directional indicators imply that the formation was derived from a terrane consisting of igneous, high-grade metamorphic, and sedimentary rocks (Morey 1967). Morey’s study agress with what Ojakangas and Matsch put into the Minnesota’s geology book. Both of these studies state that the sandstone came from the weathering and erosion of the igneous and metamorphic rocks. These igneous, metamorphic and sedimenatry rocks all came from the volcanism that occurred earlier in Minnesota’s…

Adair Park Field Trip was a really great experience where you get to see many different types of rocks and many diverse examples of minerals. This trip happened on Saturday November 1, 2014. Several geology classes went to the field trip for the expedition, with the purpose of learning the different types of each rock and its minerals and also to identify the stones from oldest to youngest. The group leaders of this trip were several professors of geology. Professor Croxen, Garrett, Dr. B, did…

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…

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…
