Essay on The Science of Rocks

The collection of the rocks was based on just picking up the most amount of difference looking rocks that was possible and bringing them home to analyze. This was done for about two months from many difference locations including campgrounds, beaches, rivers, highways as well as construction sites. After about two months there were many rocks so I started to analyze and take out the rocks that were of the same kind. I found many granite, basalt and conglomerate rocks.

Despite a family history of geophysicists and rock enthusiasts, I’ve never found the subject of rocks particularly fascinating. However, an exploration of Earth Science has lead me to the discovery that rocks are actually hidden gems (often literally), and that there’s more to the topic than one would think.

Next, we can see that the rock displays a subtle porphyritic texture with plagioclase comprising the phenocrysts. The overall texture of the surrounding groundmass is granoblastic equigranular. Under thin section we also see a weakly defined foliation evidenced in the preferential alignment of actinolite grains and to a lesser extent chlorite grains. Undulose extinction is also observed in quartz indicating the rock was subject to deformation. The normalized quartz, alkali-feldspar, and plagioclase (QAP) values of this rock indicate that it is classified as a grano-diorite according to the IUGS QAPF classification system which is consistent with the hand sample interpretation.

1. Observe the rock pool and the surrounds for litter, oyster shells, footprints, fishing wire, as well as other forms of human interaction.

The event of September of 1957 Arkansas was part of a movement that change the world as we know starting with The Little Rocks Nine. Nine African American students were placed in a white only school district in hope to merging into a better enhancement and transformation of a country that isn’t a reflection of racial inequalities and segregation. Meanwhile, it was an event that was fought and rebel against by many white officials and citizens in effort block these students from entering the schools because it was in the era's when the Jim Crows were still in effect. Many couldn’t accept revolution because they were content with where its stood then Therefore, bigotry behavior was accepted and consider reasonable. However, all African American

ROA’s situation is defined largely by recent financials. They have demonstrated year over year decline in revenue, profit, and net income since 2003 as demonstrated in Figure 1 (below). (MSN Money, 2008)

If you’re anything like me and you see this painting of “The Rock” by Peter Blume (1944), you may wonder what in the world is going on in the picture. At our first look, we see the obvious; the enormous rock Peter Blume placed right in the center. After looking at the scenery going on, I think that the placement and size of the rock is proportioned that way as a sign of it being significant. The way I see it, the monument plays an important role when it comes down to determining why there are so many things going on at once in the painting. With the comparison of the details of the hard working people to the broken rock, half built building, and the smoke, I will establish the reasons of why this picture shows both destruction and loyalty- and the ways destruction in this painting also results in uniting the people working.

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

Sand is a conglomeration of rocks and stones that have been broken down into sediments.

mafic rock, with predominance of mafic minerals pyroxenes, olivines and calcic plagioclase; these rocks (example, basalt) are usually dark colored, but not always, and have a higher density than felsic rocks. ultramafic rock, with more than 90% of mafic minerals (e.g., dunite)

They are alkalic basalts and very similar to those found from the Raton phase, both chemically and petrographically. ((http://gsabulletin.gsapubs.org/content/80/7/1343.full.pdf) The Capulin Phase includes several different stages, all which occurred during the Pleistocene. All of the Capulin Phase flows are composed of Capulin basalt, which is a fluid lava containing 50% - 55% silica. They have a relatively high percentage of silica for a basalt, because of the presence of quartz grains. These grains came from sedimentary rocks underlying the volcano, e.g. the Dakota Sandstone. The earliest stage of this phase, Mud Hill, formed during a phreatomagmatic eruption, which means that it was driven by the interaction of magma and water, followed by basalt flows. That was approximately 1.7 million 30,000 years ago. The First Series lava flows happened simultaneously as the cinder cone was forming. They flowed east, originating from fissures or series of small vents. The eruption which formed the cone itself, consisted of fissures or several small vents which joined together into one main vent, and the pyroclastic material erupting built up around the vent forming a cone. This eruption lasted for a period of weeks to years, about 55,000 2,000 years ago. The next stage of the Capulin Phase was the Boca eruption. It occurred after the eruption of the main cinder cone had ended, and because the activity shifted from the

The Rocks is one of the oldest areas of the Sydney area, therefore it features a range of amazingly beautiful old historic and heritage-listed buildings. The Sirius building, for example, was designed and built between 1978 and 1979. The Rocks locality features Brutalist architecture, buildings which are now used as residential apartments. The historic architecture and history of The Rocks are not the only interesting things that make it appealing.

The upper layers of sedimentary rock were lighter in colour and the texture was sandier while lower layers were a deeper grey colour and the particles were finer in texture and silt or clay-like. The fossil layers were restricted to certain areas on the cliff. The more northerly areas were lighter yellowish and light brown sandy layers. Moving further along the coast line were the darker grey layers which could be followed along the distance of the cliff.

The New Madrid Seismic Zone is also known as the New Madrid Fault Line. A fault is a thin zone of crushed rock that separates the Earth’s crust. Whenever an earthquake takes place, it occurs on one of the faults. Then the rock on one of the sides slips with respect to the other. The fault line is made up of reactivated faults. The reactivated faults formed when North America began to separate. Faults were formed next to rift and igneous rocks were formed from the magma that was pushed up to the surface (Wapedia (2010). The rift was covered with younger sediments. The sediments that covered the rift included Mesozoic and Cenozoic sedimentary rocks of the Mississippi embayment. Large amounts of the sediment was loosely consolidated, soft and sandy as a result of the ground shaking, ground deformation, slides, slumps, and liquefaction. A mass of intrusive igneous rock (also known as pluton, mass of igneous rock and a deep reservoir of magma)

     Igneous rocks are classified first by texture. This is broken down mainly into grain size. First there are intrusive, or plutonic igneous rocks. These types of rocks cool within the crust and forms large, visible crystals. The opposite would be extrusive, or volcanic rocks. These cool at the surface rapidly, forming small grains. A combination
