Hot Springs Observation Paper

Located just outside of Moab, Utah, the Arches National Park was underwater 300 million years ago. After the seas dried up, they left thousands of feet of salt. Soon, the layers of salt were covered in sand and other sediments. All of the sediments pressed together and formed sedimentary rock. The red rocks were deposited over millions of years to be the way they are now. During those years, erosion has shaped them into what they look like now. Soon, the water flowed through and didn’t give the top rock any support and collapsed. Caused by erosion, the water flowed through narrow cracks and made canyons.

The youngest of these rocks are dated at about 220,000 years ago. Rhyodacties and quartz latites in the modern caldera area extruded from about 320,000 years ago to 260,000 years ago, and then silica-rich rhyolites at Glass Mountain northeast of the caldera erupted from about 210,000 years ago to 80,000 years ago. The scattered distribution of the initial mafic eruptions indicates that they were erupted from the mantle, while the slightly younger domes and flows were from a deep-crustal source. The youngest rhyolite eruptions erupted at the northeast rim of the caldera at Glass Mountain and were the first activity of the silicic Long Valley magma chamber (Bailey, et. al., 1989).

Introduction - For the period of Sunday, August 28th – Sunday, September 4th, 2011, students from the University of Saskatchewan geological sciences department along with professors Dr. Kevin Ansdell and Dr. Kyle Larson took part in a geologic field school in and around the city of Flin Flon, Manitoba. The purpose of this field school was for students to

The country rock was identified in the field to be a Meta-Limestone, but a more in-depth chemical analysis done by others classifies it as a dolostone of the Strath Suardal formation from the Durness group. (Digimap, 2017) (Goodenough et al. 2011)

As I looked out the window, I saw walls of rocks all over the place. I also saw a lot of good rock exposure on the top of the mountain where the rock was to steep for the snow to stick to. You will notice that Mount Baker has an abundance of all sorts of rocks. From the rocks I examined I observed a lot of extrusive igneous rock, metamorphic rock and sedimentary rocks and you will find few places where you can walk continuously from shale or basalt into well-metamorphosed gneiss (Tabor & Haugerud). I observed rocks such as gabbro, shale, and types of extrusive and intrusive igneous rock such as basalt. The ages of the rocks range from about as old as the mountain, which is about 140,000 years old.

The study is carried out in Bicentennial Park to investigate and analyse the local area and expand on the understanding of geological and climatic concepts that can be identified through careful analysis of the area.

Welcome to our first stop on this tour, NAU, also known as Northern Arizona University! Most of you guys go to school here, but for those of you who come from somewhere else, here's a brief geologic description of this area, the amazing city of Flagstaff. Flagstaff has many geologic wonders and is found on the southern part of the Colorado Plateau. A small portion of Flagstaff's northeastern rocks are sedimentary, like limestone, dolostone, quartzite, and shale, which were all deposited in the Paleozoic Era. The north region of Flagstaff is mostly volcanic rocks, like basalt. However, the west region of Flagstaff is mostly made up of limestone and again, basalt. Some of the geologic wonders that you can see here in Flagstaff are the San Francisco

The latest rocks in this region were formed in Pleistocene time as imperfectly consolidated gravel of river terraces and alluvial deposits of the

Although you are only required to respond to the questions in this worksheet, you are encouraged to answer others from the text on your own.

On the first side of the outcrop the rock when examined was greenish and had small black grains indicative of diorite with hornblende giving the green color. The rock was similar to the outcrop encountered at Hollow rock which also had several fractures parallel although not as many, and that outcrop was also highly weathered. On the other side of the outcrop, the rock was incredibly different. This side was not weathered beyond recognition but

In Colorado, we have marble, sandstone, and granite, being metamorphic, sedimentary and igneous rock from left to

The Slave Structural Province is a unique and distinctive Archean craton in the northwest Canadian Shied, which is indicated by its rock types, deposits and structures (Padgham,1992). The Slave province covers much smaller than (1/10) that of Superior Province, which is about 213 000 km2. The supracrustals (33% of Slave province) consist of 70-80% of greywacke- mudstone and approximately 20% of volcanic rocks, which is high in SiO2 (felsic to intermediate) (Padgham,1992). There are abundant mineral deposits in the Slave Province: gold deposits, rare-element-rich pegmatite and zinc-lead-silver-concentrated volcanogenic massive sulfides (VMS), which differ from the high contents of copper-zinc-gold in the Superior Province (Padgham & Fyson, 1992).

The only types of rocks found in Big Bend National park are Sedimentary (N.P). The specific names for these rocks are: limestones, shale and sandstones, clay, Lava Flow, Conglomerate, Marl, and Cherty Limestone are found in this park (N.P). These rocks were likely abundant throughout the park; when the area was covered by a salty sea during the Cretaceous period (N.P). The way how these rocks formed is by the results of pebbles being cemented together. Another way how the rocks can form is by how the earliest layer of rock was deposited in a relatively deep marine environment. After the next layer above the shale indicates that the rock is deposited in a very shallow way, that's when the ocean water starts

The Tuscarora formation is in the Silurian age, located in Pennsylvania, mostly composed of quartzite, and is secondarily composed of sandstone. Its thickness is 150-200 feet and is in the lower part of the Silurian age. The Tuscarora formation is in the Clinton group. One member would be Castanea located at the top of the Tuscarora Formation. The depositional environment is, as we know it, a continental shelf of some sort of marine zone because of sediment structures like fossils and cross-bedding. The Tuscarora formation is mainly non-porous and neither

Where the rock is found: Much of the mountains in the north of California and southern Oregon is pieces of broken up seafloor crust estimated to be 150-450 million years old. While most of eastern Washington and Oregon (the Columbia River Basalt), and north eastern California (the Modoc Plateau Basalt) are underlain by flood basalt.
