The purpose of this paper is to compare the angular basalt cobbles lining the paved trails at Hell’s Half Acre with samples taken from the basalt flow at the same location in order to determine if the cobbles are from the surrounding lava flow. A trip was made to Hell’s Half Acre where observations were recorded and three samples of both the basalt from the trail and the flow were collected to visually compare physical and mineral properties. The study area is a unit of relatively young Quaternary lava flows found on the Snake River Plain known as Hell’s Half Acre. Trails through the lava flow are located at the Blackfoot Rest Area on I-15 in southeastern Idaho between Blackfoot, Idaho and Idaho Falls, Idaho. All observations were made and samples collected from the trails at the northbound rest area. …show more content…
The rocks are pebble to cobble sized basalt fragments. The samples collected ranged from 50mm to 120 mm. The rocks are angular. They have a gray, very fine ground mass. Fine plagioclase feldspars are visible throughout the ground mass and sparkle in the sunlight. The rocks do not show signs of heavy weathering. There is some white staining visible, but there is very little red or brown staining. The rocks have abundant vesicles. There is a mix of rocks with varying sizes and numbers of vesicles. Samples collected were representative of this mix. Light green olivine phenocrysts are visible with the naked eye and more are visible when viewed through a hand lens. The olivine is visible on both weathered and fresh surfaces in all three samples. Also found mixed with the basalt rocks lining the trails are intermittent sub-rounded quartzite pebbles and
The poorly sorted nature of the conglomerates, considered with the inclusion of wood fragments in the older conglomerate members and the graded sandstones and mudstones throughout the formation suggest deposition occurred through successions of debris flows. Presence of volcanics in the lithic fragments further indicate volcanic activity in the process of sedimentation as well—as debris flows associated with lahars are the likely source of the slope failures. Deposition environment was moderate to deep marine, as mudstone deposits require low energy depositional environment, but the style of sedimentation indicate deposition was not on a continental shelf. This is further supported by inclusion of the large overturned clast from an older member within the formation. Cross-bedding, graded bedding, and scouring surfaces provide 3 lines of evidence establishing the northern contact of the formation as the original upward oriented surface.
There are a four requirements to be met before a potential client can become a member of Spring City Corner Clubhouse. He or she must have a diagnosed mental illness, the person must at least be eighteen year of age, residing in the county of Waukesha and no major criminal history. He or she does not have to belong to any particular nomination or any religious organization. There is also no statues that dictates the sexual orientation of a client.
After interviewing Sergeant Tumlin, an interview was conducted with Mr. Paul Owens who was an employee at MUV Fitness Forest Acres for approximately five years. Mr. Owens was asked about the community’s political structure and if it is active politically. He responded stating Forest Acres has a city/municipality political system and is influential politically; making it one of the more established communities in Columbia. Also, he reported that the city council members and state legislators impact the community and makes many of the decisions for certain policies and laws enacted in the area and that these members are of Caucasian decent as well. Mr. Owens was then asked if he had any knowledge about zoning and coding enforcement; responding that the community has a strict Zoning
In A Paradise Built in Hell, Rebecca Solnit focuses on the occurrences of the aftermaths of five major North American disasters and how strong bonds within communities form because of those disasters. Each case study provides a concrete description of what surviving residents themselves understand to be an unusual sociological change arising in the midst of casualties, disorientation, homelessness, and significant loss of all kinds. Reflecting on the 1906 San Francisco earthquake; the enormous 1917 explosion in Halifax, Nova Scotia; the devastating 1985 Mexico City quake; Lower Manhattan after the 9/11 terrorist attacks; and Hurricane Katrina’s 2005 deluge of New Orleans, Solnit brings a new perspective to these heart-wrenching tragedies. Solnit tells many enlightening stories of altruism and courageous social action. Moreover, although providing insight on these tragedies, Solnit presents her case with a redundant political bias and can seem to show problems that were not there.
Dear_________________ The board of directors of the Trinity Park Cemetery is proposing that the First Trinitarian Congregational church transfer ownership of the Cemetery to our “neighbor,” the Fairview Cemetery. The Church Council agrees with this proposal. Our church established Trinity Park Cemetery in 1997, following a gift of land. The original plan was to use the sale of cemetery plots to establish a fund for the care of the cemetery in perpetuity.
King Ranch “The birthplace of American Ranching” - Robert Kleberg. The King Ranch is one of the biggest ranches in the world. The King Ranch has many thousands of acres, and has over 20,000 head of cattle. The owner of the King Ranch is Robert Justus Kleberg, and they have several employees that help work the multiple lands owned.
For example, experts say, “The three sets of rocks are differentiated on the basis of not only stratigraphic position, but also age, rock types, and overall geologic setting in which they form.” One of the types of rocks found there are crystalline rocks which are exposed near the bottom of the canyon. Another type is sedimentary and volcanic rocks found in the coastal basins which tilted when the continents split apart. Lastly, the Paleozoic rocks at 3,000-4,000 ft. which is flat-lying sediment rocks that create the “stair step” canyon.
Richard A. Muller a professor of physics at the University of California, Berkeley, expresses his concerns on the subject of nuclear waste. In his essay, Nuclear Waste, he writes about where the United States stores its nuclear waste, alternative ways to dispose of the waste and whether it would be effective. He also talks about how dangerous the nuclear by-product is, and other dangers regarding civilian’s safety. He effectively explains his concerns through pathos, logos, ethos, and other uses of examples to help readers understand his concerns. He attracts readers by talking about the future generation and their safety against potential nuclear waste contamination.
I am writing to enthusiastically support Emma Idol’s application for a GIA Graduate Gemologist (GG) On Campus Scholarship. I have known Ms. Idol since the Fall semester of 2014 and have been her instructor in two senior level geology courses, including Structural Geology, and notably, our six week capstone Geology Field Course in Italy. Perhaps more importantly, Ms. Idol has been conducting research with me and a colleague in a collaborative geologic hazards project entitled Determining the history of landslide activity using dendrochronology, highway 105 in Boone, NC. These experiences have afforded me a substantial amount of time to get to know Ms. Idol; I feel very well qualified to speak to a number of her qualities.
Simply put, marble is just limestone that has been exposed to heat and pressure for an extended amount of time. Because it is formed by applying heat and pressure over time, it is considered a metamorphic rock. Complexities arise when impurities are introduced to the limestone undergoing crystallization. Many things can change the mineral composition of marble, such as silica. When silica is present then carbonate minerals form masses of quartz or chert crystals, but only at lower temperatures of formation.
Iridium was found in samples from the K-T boundary, which marks the division between the Cretaceous and Tertiary periods (“Extinction”). Iridium happens to be uncommon in the Earth’s crust, but profuse in meteorites. Besides containing
In the hydrosphere, all dissolved down in the groundwater, was me; a carbon molecule. For hundreds of years, I have been there, mixed with the water below, until I precipitated out. I ended up at Havasu Falls in travertine. Usually, travertine consists of deposited minerals from mineral springs, and my journey has taken me to combine with other carbon molecules joined in a form of limestone. I have been soon on my way into a new destination to the limestone lithosphere.
