Riven Rock

be used to represent the sedimentary rock. The goal is to see if different amounts of alum powder will affect the amount of crystals that grow. In this experiment, the groups’ hypothesis is the more alum powder in the solution, the bigger crystals will form. A geode is a “mass of minerals within a rock that can take thousands of years to form” (Steve Spangler). The word geode is from the word Geoides, which is considered “Earthlike” (Wonderopolis). These rocks form geodes when…

ancient siliciclastic sequences of river sediments. The value of the technique lies not only in the number of possible minerals, but also in that many of them have petrogenetic parageneses that positively identify the involvement of particular parent rocks. Single grain analytical methods have been most successful in constraining provenance compared with bulk methods (Gehrels et al., 1995; Mange and Morton, 2007). This approach is based on the principle of finding a diagnostic and distinct…

lay large 60 degree a ngeled slabs of rock known as the Flatirons. Over millions of years sediment become compressed into these layers of rock. Clues to what may have caused the tilted sedimentary layers are the darker rock at the bottem called granite, which has no layering like the rock on top of it. The garnite full of menerals showing signs of magma, from a liquid rock. From class I know that magma is usually found deep within the Earth. But this rock has been pushed up causing a tilting…

was observed to be igneous rock, with evidence of batholith, an igneous specific type of intrusion that spans for miles at a time. This is evident in figure 8. Various minerals and a grainy texture were also observed. Because of this, and identification of minerals such as quartz, as observed in figure 6, and orthoclase, in figure 9, this rock was concluded to be the igneous rock, granite. Granite forms when magma under the Earth slowly crystallizes. Igneous rock forms when there is an…

Sediment-hosted copper deposits are formed by fluid mixing in permeable sedimentary and (more rarely) volcanic rocks. Two fluids are thought to be involved: an oxidized brine carrying copper as a chloride complex, and a reduced fluid that commonly formed in the presence of anaerobic sulfatereducing bacteria. For a sediment-hosted copper deposit to form, four conditions are required: (1) an oxidized source rock, (2) a brine to mobilize copper, (3) a reduced fluid to precipitate copper, and (4)…

There are many land formations and I chose these three. The first one is a canyon, it’s located in Arizona and its name is Grand Canyon. The second one is a volcano it’s found in Washington State, Cascade Range and it is named Mount St. Helens. The last one is a plateau and it can be found in central Asia and it is called Tibetan Plateau. And then I’ll be comparing the different land forms. The Grand Canyon is in Northern Arizona with an elevation of 8,000 feet. The process of the…

exposed rock material has a visible reverse fault, and is heavy faulted/folded. Visible soil, and vegetation growth on exposed section of the formation. Visible iron oxide staining from fractures in the section both natural, and manmade. Alternating material layers light grey to dark grey in the formation, and thick bands. 0 to 3feet of the section is composed of light grey, and soft material. The bottom facie was a small section of laminated layered shale. 3 feet to 6 feet of the exposed rock…

Questions and Answers Rock specimen “A” is identified as marble. This sample had a white to cream color to it, which is an identifying characteristic of marble. Another characteristic is the calcite inclusion; this inclusion is seen by bubbling when exposed to a saturated citric acid solution. When viewed by the unaided eye, the grain and crystal structure is clearly seen. While marble is supposed to be a fairly soft rock, the example provided proved to be fairly durable which was tested…

The Pinturas Formation (Middle Miocene) includes a sedimentary succession exposed at the Río Pinturas valley, Santa Cruz province, Argentina. It is separated in three members. The lower and the upper ones were dominated by ashfall episodes with paleosol formation during stability times; while the middle member is represented by desert eolian deposits. Mentioned palaeosols bears a moderately diverse ichnofauna. Trace fossils presents are Coprinisphaera murguiai, C. ispp., Loloichnus baqueroensis,…

till. The sandstone was the oldest in the formation of rocks dating back over 550 million years. It was a layered set of sandstone and was folded. The elevation was less than 1,000 feet and its thickness was approximately 115. The next oldest in this area was the Ordovician dolomite. This is roughly 505 million years old. It was bedded flat and had layers. Its elevation was also less than 1,000 and the thickness was approximately 20. The newest rock in the area was the quaternary till that was…
