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…
understand the formation of the Himalayas. Some of these are the rocks collected…
as precise of a rock name as you can, and an interpretation of the (possible) environment of formation. Quaternary: This is an igneous rock known as Tuff pyroclastic, which is a volcano-clastic rick composed mainly of volcanic ash. This conclusion makes sense as the quick cooling would cause the porous structures. This rock possesses sand to mud sized grains; therefore it is fine grained. This rock has interlocking crystals as well as a predominately mafic structure. This rock contains K…
trips over the cable and he falls and the cord and the tank go flying away with a loud whoosh! I started freaking out thinking as fast as I could to get back to the ship without Will dieing. “Miranda help!” Will said as he was slowly dieing from the hard impact of the earthquake and the air that he was breathing in. I had no idea what to do so I tried to open my tank to try and get him to receive some of my air so he won’t die. It worked! And we are now trying to head back to the spaceship…
fault; the St. Nicolas fault which brought the Manhattan schist. There were observations of boudins of quartz, which are kinetic indicators of movement and stress on the rocks (Flores, 2016). In the Manhattan schist basaltic intrusions were also observed and contact of the intrusion zone. The pegmatites, which are igneous rocks, observed pointed to the Acadian orogeny which followed the…
Earth is composed of many different components such as minerals, and rocks. These components have several different properties and characteristics which are unique to each. In this paper, I will discuss some of the different properties, characteristics, and uses of three different factors, those being gypsum, coal, and nickel. Gypsum Gypsum is derived from the Greek word gypsos which means plaster (Gypsum Meanings, Powers, and History). Gypsum is composed of oxygen, calcium, sulfur, and water…
sandstone and shale. Then an intrusive magma that made its way through the crust, only to cool and become granite and pegmatites. This magma changed the existing rocks making schists and quartzite. After the inland sea receded erosion dominated the area eroding many layers of rock that had been deposited. A massive uplift rose these rocks to 15,000 feet. The erosion process eventually got rid of the sedimentary layers, exposing the granites and metamorphic knobs that we see today. Imagine if one…
Initially, the most striking feature of Eroded Rock, Point Lobos, a gelatin silver print by Edward Weston, is its relationship between positive and negative space. The photo’s subject is an eroded rock, whose rough, raised plateaus create a light positive space and emerge from smooth, blackened sections of the eroded rock which create the image’s negative space. These sections of eroded rock envelop the plateaus in languid serpentine lines, almost as though the plateaus are land masses cast…
During the Scottish Enlightenment, a period of increased intellectual activity in the 18th and early 19th century, individuals tended to explore multiple disciplines of study (Young, 2016). One prominent Scottish Enlightenment figure was James Hutton, living from 1726 to 1797. During his lifetime he was a lawyer, geologist, chemist, physician, farmer, and naturalist. Hutton, along with other prominent Enlightenment figures, Joseph Black and Adam Smith, founded the Oyster Club. This intellectual…
