Tectonics

During the later stages of ore formation, Mn filled veins and veinlets of fractures and joints of the host rocks. The mineralized horizons (laminate and bands) are locally boudinaged and cut by the veins and veinlets, indicating that the role of tectonic activities and fault rupturing during the late stage of Mn mineralization in the area. However, emplacement of Eocene-Oligocene intrusions have also affected the ore bodies in the Venarch mine deposit and produced different alteration minerals…

Geometry and Eratosthenes In Professor Russ physical science class, there’s a plethora of subjects you, as a student, are bound to cover. This semester we had discuss over twenty different fields of science; the first being Geometry and Eratosthenes computing circumference of earth. We started the final semester off with two worksheets. The first was the “Angles of a Triangle”, we had to cut out the three angles of the triangle and piece them together in a shape. The three angles form a…

Alfred Lothar was a famous scientist and lived from 1880 to 1930. He was born in Berlin, Germany. He got a PhD in astronomy but soon wanted to study meteorology and paleoclimatology. He continued his work in Germany and Austria. He was most famous for his continental drift theory. Alfred Wegener stated his theory in 1912. His theory stated that all the continents were once all joined together but slowly drifted apart as time went on. He called it Pangaea. People did not believe him until the…

That is why, despite not being the closest planet to the Sun, Venus is the hottest planet in the Solar System. Earth 's Tectonic Plates: the tectonic plates of our planet are portions of what is scientifically called "lithosphere", which accounts for the layer of the Earth that contains the terrestrial crust and the upper-most solid mantle. Tectonic plates account for many interesting phenomena - such as the formation of volcanoes and mountains, and the generation of earthquakes and…

9. Define the terms subduction, mid-ocean ridge, and ocean trench and island arc. Subduction is when two tectonic plate’s convergent boundaries come crashing together resulting in one going below the other. This results in the bottom plate to sink into the mantle. Mid-ocean ridge is an underwater mountain ridge that forms when convection currents causes magma to rise where two tectonic plates meet at a divergent boundary. Ocean trench are long narrow depressions on the sea floor as a result…

TECTONIC HISTORY The Smackover Formation of Texas is located in the East Texas Basin, in North-East Texas, and is “one of three Mesozoic basins flanking the northern rim of the Gulf Coastal Plain” (Foote et al., 1988, p.3). “Subsidence from rifting and crustal attenuation in addition to subsequent sediment loading results in a maximum of 23,000 feet of subsidence in the center of the basin” ( an idea originally published in Seni and Jackson,1984, quoted from Foote et al., 1988, p.3). The area…

Abraham was still walking among the earth. The eruption of Mount Vesuvius occurred on August 24, 79 AD, and is often referred to one of the greatest cataclysmic events in European history according to our tour guide. Volcanic eruptions and movement of tectonic plates in any state, form, or fashion have the absolute power to kill everyone in close…

billions in public taxpayer funds to rebuild after the damage. There are several types of gravitational forces that occur within the earth and cause earthquakes, such as plate tectonics and seafloor spreading. Understanding these actions can allow us to have better understanding of the causation of earthquakes. Plate tectonics is the theory that states Earth’s outer shell is divided into several plates that glide over the rocky inner layer of Earth called the mantle. The theory began in the…

The Alaskan way Viaduct will collapse if an earthquake happens, but that earthquake will take many steps. These steps will got through the layers of the earth. The layers are stacked on top of eachother, like the liquids in the “Density Column lab”. The layers are inner core, outer core, mesosphere, asthenosphere, and lithosphere(upper rigid mantle, continental crust, and oceanic crust). The earth's compositional layers are inner core, outer core, mantle, and crust. The inner core radiates…

beautiful hot magma that flows from the volcano is dangerous and burns everything in its path. Two volcanoes that have always caught my eye is Hawaii’s Kilauea and Japan’s Mount Fujiyama. Both volcanoes are located on an island that was formed due to tectonic plates shifting, furthermore both volcanoes represent different types of volcano forms, however, Hawaii’s Kilauea volcano is still active while Japan’s Mount Fujiyama has not erupted since between 1707-1708. Havelock Ellis once said, “All…
