The Elena Gallegos Open Space area sits near the base of the Sandia Mountains on a piedmont surface. This exercise was intended to gain insight into the mountain-front landforms of the Pino Embayment area. Through the use of surficial geological mapping and soil descriptions we were able to establish relative ages of geomorphic surfaces of the area and determine whether the area displayed qualities of alluvial fan and pediment surfaces. The geomorphic setting of the study area showed…

Plate tectonics is a scientific theory that describes the large-scale motion of Earth’s Lithosphere. The theory was believed to be developed around 1912 by Alfred Wegener. Wegener introduced the fact that all of today’s continents were once a large supercontinent (Pangea) and how they slowly drifted to their present positions. This idea was developed by simple observations such as the fact that the African and South-American coast lines fit together like pieces of a puzzle and that fossils and…

Annotated Bibliography [1] R. Holtz, W. Kovacs, T. Sheahan. An Introduction to Geotechnical Engineering, 2nd Ed. New Jersey: Pearson, 2011, pp. 294-301. Liquefaction is a phenomena that appears in not very cohesive soils. There are many factors linked to the existence of quicksand. Holtz, Kovacs, and Sheahan describe how the seepage forces, liquefaction, earthquakes, soil stress and underground water table are crucial elements to the understanding of quicksand. Additionally, the book provides…

GOLDEN GEOLOGIC HISTORY REPORT It all started with the Big Bang then the whole universe is formed, continued with the formation of the Milky Way, where there is a solar system with the planet Earth and then there were this little town called Golden. This is a report that will travel through time telling the stories of the incidents happened in to this town of Golden. During our journey we must note that the whole geological of Golden is tilted and there were mining done here. Let’s start our…

1. Spiral Jetty was created by Robert Smithson in Great Salt Lake, Utah, 1970 from earthwork. 2. The Spiral Jetty is arranged into a spiral shape along the water of the Great Salt Lake. The emphasis of the earthwork draws the viewer into the center of the shape along the spiral, as this part is larger and more filled. The work is arranged in a unified pattern, especially as the textures and colors are all the same throughout the shape. The core of the spiral, as the largest part of the work, has…

The Mt. Isa Mine is a deposit of copper, lead and zinc. It is located at latitude 20∘44’S, longitude 139∘29’E and is in Queensland (Forrestal, 1990). Generally, this ore deposit contained 123 g/t copper, 5.0% lead and 7.0% zinc at 4.8 Mt. The host rock of this deposit consists of pyritic shale, carbonaceous shale, dolomitic siltstone, carbonate, granite, ironstone and metasedimentary cover rocks (Hutton et al. 2012). Deposit genesis The ore deposit genesis is considered to have occurred in…

TECTONIC HISTORY The Smackover Formation of Texas is located in the East Texas Basin, in North-East Texas, and is “one of three Mesozoic basins flanking the northern rim of the Gulf Coastal Plain” (Foote et al., 1988, p.3). “Subsidence from rifting and crustal attenuation in addition to subsequent sediment loading results in a maximum of 23,000 feet of subsidence in the center of the basin” ( an idea originally published in Seni and Jackson,1984, quoted from Foote et al., 1988, p.3). The area…

Alfred Lothar was a famous scientist and lived from 1880 to 1930. He was born in Berlin, Germany. He got a PhD in astronomy but soon wanted to study meteorology and paleoclimatology. He continued his work in Germany and Austria. He was most famous for his continental drift theory. Alfred Wegener stated his theory in 1912. His theory stated that all the continents were once all joined together but slowly drifted apart as time went on. He called it Pangaea. People did not believe him until the…

Mining is a business directly related to the extraction of ore, valuable minerals or other geological resources such as gold, silver, diamond, iron, coal and uranium from mines. Because the process of extraction requires a large amount of capital, mining business is normally done by the government, multinational companies or wealthy business owners. All the resources that need to be extracted are non-renewable as these materials cannot be artificially created nor grown through agricultural…
