earth. The Blue topaz is found in the enormous crystals in pegmatite dikes (Topaz). Pegmatite dikes comprise extremely coarse crystalline granitic rocks (Dike ( Geology )). It can also be found in rhyolite, gneisses, and schists which are very acidic (Topaz)." Topaz crystallizes from fluorine-rich vapor in the final stages of solidification of igneous rock" (Topaz). Topaz can also be found in…

Abbylyn Sessions Professor Livingston Geology 1100 28 August 2016 Fantasy Field Trip Just outside of Custer, South Dakota is a hidden geological treasure: Jewel Cave. Jewel Cave has over 181.89 miles in mapped passageways making it the third longest cave in the world (United States. National Park Service). The formation is lined with calcite crystals creating a beautiful view inside. Jewel cave is a geologic wonder that would make a great field trip. A field trip to Jewel cave would allow the…

The Tuscarora formation is a light-gray sandstone with quartz grains imbedded throughout it. Most exposed Tuscarora specimens were dark and weathered on the exterior but were light colored on the interior and comprised of fine to coarse grains. The Tuscarora formation is about two hundred meters thick. The Castenea formation is found in parts of the Tuscarora formation. It is typically observed as a dark brown-reddish layer binding a middle section of lighter brown fine grain well sorted…

1. Introduction Silicified wood is normally formed close to the surface due to the infiltration of buried wood with mineral-rich water and the associated deposition of minerals (Kim et al., 2009). Two typical geological environments have been reported, 1) trees transported by streams and rivers then buried in the fluvial sediments (e.g., Weibel, 1996; Fielding and Alexander, 2001; Parrish and Falcon-Lang, 2007; Hartmann et al., 2010), and 2) ash from volcanic eruptions buries trees while felled…

Clearwater Beach, FL’ and Key West, FL. Each sample has been sieved and analyzed. Because of the different locations of the sands, the composition is diverse, ranging from quartz to hornblende. This feature is determined by the parent rock, which is the source rock that has been eroded and deposited into the same area. This is usually where the sand originates. Galveston beach is known as a barrier island. Galveston Island is located south of Houston, about 50 miles. Galveston Island split up…

Why is the Grand Canyon considered a natural wonder? The Grand Canyon is visited by over 5 million people every year. Many people dream of a day to be privileged to see such a beautiful sight. It is one of the most popular of the world 7 natural wonders. It has been recognized as one of these natural wonders because of its enormous size and in addition its beautifully colored landscape. The Grand Canyon is located in the northern part of Arizona in the United States. It is among the biggest…

along cracks and faults in the limestone rock by sulfuric acid. The limestone was laid down about 250,000,000 years ago, as part of a reef complex along the edge of an inland sea. Seventeen to 20,000,000 years ago, the ancient reef rocks that had been buried under thousands of feet of younger rocks began to lift upwards. This historic park is very special because it contains more than 119 limestone caves. The cavern is special because of its many famous rock structures and its enormous room…

Dear, Principle Davis I would like to bring to your attention the 8th-grade field trip to Lava beds national monument. The monument is on the California and Oregon state border. There are about seven hundred caves in the monument. There are a couple safety concerns that you should be aware of. There are many flat-footed caves, but some raged caves that could cause some problems. Most of the caves are flat with high roofs. It's a historical and geographical landmark. Although there are some…

Ocean rocks got piled up was located in the northeast. The collision of the Northeastern part of North America and Baltica didn’t really affect the southern coast until part of Avalon called the Carolina Terrane hit the southern part. These collisions caused the rocks to be metamorphosed. North America and Baltica at this time were located near the equator and North America was moving…

and the deep ocean floors only 13 percent in volume. Another sort of sediments are pelagic sediments which are fine-grained and settled far from land, for example, siliceous oozes, calcareous oozes, and red clays. Lithogenous sediments consists of rock and minerals are also found far from shore, however, it is used interchangeably with terrigenous sediments. Pelagic sediments are slow-accumulating deposits at the average rate about 1 millimeter per 1000 years because these sediments accumulated…
