  • Description Of Adaair Park Field Trip

    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 everything possible for this trip to happen. Guess their goals for us were achieved because we had the experience to know more about how the mountains get build at the time with the movements of our nature and also to know how the rocks are made of. Once we arrived to Adair Park…

  • A Rock Sample Lab Report

    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…

  • The Appalachian Basin

    various depositional environments and the understanding of sea level change, the Appalachian Basin formed by the collision of tectonic plates and sediment accumulation under the Earth’s surface. The Appalachian Mountains reveal subsidence belts, faulted marine sedimentary rocks and other geologic rocks in these tectonic settings. The Basin exists in the northeastern states of North America. This large rock formation exhibits collisional tectonics with modern time development of shales. This…

  • Sacrifice In Northern Minnesota

    This makes the sandstone a mature sandstone. The sandstone is probably well rounded, well sorted, and well cemented if it is mostly made up of quartz and feldspar. Analysis of cross bedding and other sedimentary 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…

  • Great Valley Sequence

    By dating ammonite fossils, we know that the Panoche Formation (Mid-Cretaceous) is older than the Moreno formation. The conglomerates’ clasts have sizes around 5cm in diameter and they are round to sub-angular. Mineralogy of the clasts includes slightly metamorphosed felsic 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…

  • Fordham Gneiss

    The outcrop featured large garnets, anatexis was observed which shows two generations of garnets, pointing to the fact that there was differential or partial melting taking place (an indicator that it was an amphibolite facies). There was also evidence of a 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…

  • James Hutton: Increased Intellectual Activity In The 18th And Early 19th Century

    James Hutton’s proposals in The Theory of Earth were a turning point in the field of geology, as it established the principle of uniformitarianism, which would come to form the foundation of the geological field (Encyclopædia Britannica, 2003). Hutton’s discoveries contrasted with the widely accepted geological interpretations that were primarily based upon the Bible. The majority of people in Hutton’s time explained the formation of all rocks through the biblical account of the great flood. The…

  • Gypsum Mine Observation

    On Saturday, November the 21st, I visited the Gypsum mine with my lab group: Luke Petro, Liz Morehead, and Kylie Hoef, along with several other groups. After procuring the necessary tools from the geology lab like a 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…

  • The Importance Of Existance Of Lake Malawi

    2.4. Hydrocarbon potential Previous work reveals presence of mature sedimentary sequence was derived from Jurassic to lower cretaceous periods in the north part of Lake Malawi which has hydrocarbon reservoir prospects. Existence of thick sedimentary sequence rock could possibly trap hydrocarbon especially in lower Shire valley, northern of Lake Malawi. Presence of large proportion volcanic clasts interbedded with sedimentary rocks transported by rivers present for extensive alluvial plain…
