GEOLOGIC SETTING AT OUTCROP The rocks of the Wilberns Formation have a very involved history. Today, the Wilberns outcrops are found in the Llano uplift region of central Texas, the most prolific Wilberns outcrops are to the west of the Llano uplift area (Bell and Barnes, 1972, p. 28). The Llano uplift area is a geologically complex region of central Texas (fig. 3). Precambrian metamorphic and plutonic igneous rocks mostly dominate the Llano region. The uplift brought Cambrian Wilberns rocks to…

Ian Miller is a Paleontologist who works for the Denver Museum of Nature and Science. Ian Miller’s problem is that he wants to find out how Western North America changed from the past 100 million years, what past climates were like 100 million years ago and the fossil ecosystems that existed 100 million years ago. Through solving and studying this problem, there have been many obstacles to solving his questions. Although obstacles causes trouble and hardships through experiments and test, Ian…

River otters can stay underwater for up to eight minutes and can close their ears and nostrils to keep water out! They can also dive to a depth of 60 feet!The otter is a small mammal that lives both in water and on land. There are 13 known species of otters that inhabit areas around the world Otters have a thick coat of fur which enables the otter to be warm in near freezing waters. There is also a series of thin hairs under the otters fur that help to trap air and keep the otter warm. The river…

week’s reading from chapter 5 ocean sediments, I learned a lot about sediments and different types that I never knew existed. The ocean the floor and particles moving around the ocean are actually called sediments. The sediments accumulate at a rate of centimeters in a year. Sediments are caused by various things happening inside of the ocean such as volcanic eruptions, rocks eroding, chemical reactions in the water and evidence of space matter. These sediments are classified into four…

kinds of sediments, their origin, color and its contents. For example, biological sediments are white or cream color. Deep-sea clays are ranging from red to chocolate brown color because of the oxidation or rusting of iron within the sediments to form “iron oxide” which is basically rust and nodular sediments are dark brown and black. However boulders, cobbles, and pebbles made of better-quality particles which is sand, silt, and clay and they are defined by particle size. The sediments, like…

Introduction Beach morphology is a key factor in helping determine the sediment interaction between not only the ocean but the surrounding environment as well. On September 23rd, 2016 at 1500-1645 hours’ group 3 of MSCI 112 collected local data of the morphology of Myrtle Beach State Park, SC, US. With the help of the data collected on site as well as the data collected in the lab our main objective is to able to learn more about the impact on the beach as well as the interactions it has with…

Isolation is a common theme among Canadian literary works. Farzana Doctor, in her novel Six Metres of Pavement, uses depression as a tool to illustrate the isolation of the main character from society. The theme of isolation is developed through Ismail Boxwala’s journey from self-confinement to self-acceptance. Ismail’s oppressive past consequently severs his connections, which causes him to be isolated. The desire Ismail has to find something that will help him out of isolation is conspicuous,…

In this study, sediments from a mangrove ecosystem in Sepetiba Bay was utilized for investigation since Zinc is the major contaminant in this region. In the laboratory, researchers used radiotracer 65Zn with half-life 244 days to undergo the experiment. Among the isotope of zinc, 65Zn has the longest half-life. Since it is the first time to study the removal rate of Zinc, a stable Zinc use can result in a better understanding of metal uptake kinetics. First, the core sediment samples were…

excavated hole, resulting dense and waterlogged soil which is a possible outcome of excavation as well as human presence and construction equipment. Once excavation of the first pipe begins there will be a displacement of small volumes of soil and sediment around each section of pipe. These are to be stored on site and used to fill the hole after the pipe is placed. Any excess is to be collected by trucks and transported elsewhere. A portion…

One type of sediment to note is diatomaceous earth, an uplifted siliceous ooze which contains the remains of the microscopic algae known as diatoms (Garrison and Ellis 152). With a density lower than most other sediments—measured at 0.2816 g/ml in our lab results—the powdery and apparently sticky sediment has rather tiny grains as expected from this sort of sediment. As diatomaceous earth derives from the diatom ooze of the deep ocean floor, it originates from the slow dissolution of diatom…
