Geology and Lithology of la Sierra de Guadarrama
What is Geology and Lithology?
Geology is the science that studies the origin and formation of the earth and the materials that compose them and Lithology is the science that studies of the rocks in an environment.
Types and Characteristics of the Rocks:
There are lots of types of rocks that the geologists studies, in Sierra de Guadarrama there are some type of rocks like: plutonics, metamorphics, sedimentaries and dykes rocks. Also the most antique rocks are the gneiss, marble and schist (Those are Metamorphic Rocks).
Plutonics Rocks:
Plutonics rocks are igneous rocks that had been melt at a deep distance. The most common type of plutonic rock is the granite. The granite of the Sierra de

In Sierra de Guadarrama these rocks are 30 km underground and at a temperature of 750ºC The gneiss is a metamorphic rock due to the high temperatures and pressures in the interior of the earth's surfaces, it’s composed of quartz, feldspar and mica. The genesis is one of the most important rock in Sierra de Guadarrama due to its antiquity of 450 million years …show more content…
This pieces can be of multiple sizes and are carried by wind, water.
In la Sierra de Guadarrama there are three types of Sedimentaries Rocks: marl, limestone and dolomite.
Marl or also known as marlstone is a mudstone that contain a high variation of clays and silt. The limestone is a sedimentary rock that is practically composed of calcite, it is the 10% of all sedimentary rocks and it is white but the clay, sand and dust it can change the colours of the rocks. Dolomite or dolostone is a carbonate rock that is mainly composed of Calcium Magnesium Carbonate.
This rocks can be found in the bottom of valleys, like in La Pinilla del Valle, that is totally exposed because the erosion that the rain caused. It is also found in the southeast slope in Sierra de Guadarrama Dyke Rocks:
Dyke rocks origin inside of the terrestrial surface, because of the solidification from magma that goes up through cracks or breaches to the exterior. It is basically a igneous rock that extend from the interior of the earth's surface into the exterior and then fall over other rocks forming vertical tall walls.
The process would
Mya Seaway Research Paper
1677 Words | 7 PagesPierre shale is a formation of marine origin from the Cretaceous period that resulted from the Western Interior Seaway. The formation stretches from New Mexico to North Dakota, is up to 700 feet thick and rests on top of the Niobrara formation. The Niobrara Formation is a geological formation that appeared around 87-82 Mya during the Cretaceous, also a result of the Western Interior Seaway. It is composed of two layers: a chalk and limestone layer. The chalk was formed due to calcium carbonate left behind by decomposed shells of microscopic algae that populated the Seaway.
Hell's Half Acre: A Case Study
722 Words | 3 PagesThe rocks do not show signs of heavy weathering. There is some white staining visible, but there is very little red or brown staining. The rocks have abundant vesicles. There is a mix of rocks with varying sizes and numbers of vesicles. Samples collected were representative of this mix.

Stinky Cove Research Paper
1724 Words | 7 PagesWe walked along the beach a little more and talked and looked at the location of a whale skull that used to be buried in the sand. The rock was actually much smoother than . We also took a look at some possible bones and skeletal remains along with concretions. The concretions were rather large comparable to smart car in size. Concretions are solid masses formed around some type of matter that will change the chemistry of the rock slightly, helping it become harder and less susceptible to erosion.
Cordell Formation
1484 Words | 6 PagesThe minerals were not obvious in hand sample so further mineralogical analysis would likely be needed to recognize the accessory minerals. The Cordell unit is difficult to distinguish in the field from the lower Engadine unit, the Rockview, due to the high degree of dolomitization and recrystallization. However, unlike the Rockview, the Cordell member is more thinly bedded and fossiliferous and lacks algal mats. The bottom of the Rockview dolostones appear to weather to a lighter color than that of the exposed Cordell and is considered
The Naica Mine: The Cave Of Crystals
561 Words | 3 PagesThis cave is located 1000 feet underground and contains many of the largest natural gypsum crystals in the world (2). These pillars of selenite gypsum measure up to 50 feet long and 4 feet in diameter (1). These crystals were able to form in such huge quantities because the area was submerged in water that was rich in minerals as well as having a high stable temperature of 136 degrees Fahrenheit (2). The water had an abundant amount of anhydrite and, because of this environment, it dissolved into gypsum and formed these massive crystals (2). The water has since drained out of the caves and the air in the caves normally stays between 45 and 50 degrees Celsius and the humidity levels range from 90 to 100 percent (3).

On the rock cycle the order is sedimentary rock, metamorphic rock, and igneous rock, therefore, These three rocks are the rocks that other rocks are classified into. This tells what order the rock cycle
Sequoi Kings Canyon National Park: Geology Analysis
1195 Words | 5 Pages(Harris, 2004) The downfaulting of Death Valley is correlated with the extension of the lithosphere in the Death Valley region, which plays a part to the uplifting associated with Sequoia – Kings Canyon National Park. The Batholiths of the Sierra Nevada mountain ranges are prominent in both parks, exposing “plumbing systems” in magma chambers that fed the volcanoes. “Magmatic differentiation” involves the crystallization of a magma with magma of a different chemical composition, creating more than one type of igneous rock, which can be seen in both Yosemite and Sequoia – Kings National Parks. (Harris, 2004, 748)
How Did Water Shaped Michigan
1189 Words | 5 PagesThe water that was created from the glaciers melting carried out a great deal of the leftover debris, which was sorted into different sizes such as gravel or pebbles, sand, silt or clay. All of the leftovers started to form in layers or beds in river ways, ponds, and in lakes to form what the geologist call glacio-lacustrine formations. Glacio-lacustrine formations is just a scientific phrase for a glacier melted and the materials that had been inside the glacier deposit into the lakes and rivers created by the melted

1389 Words | 6 PagesAnother type of layer is called the Terrestrial Fossils. In this layer there are several rock layers and fossils that form this whole layer. Some layers are called the Hermit Shale, Supai Group, Coconino Sandstone, and Surprise Canyon Formation. There are many types of fossils called leaves, Tracks, and Dragonflies.
Manchester State Park Case Study
511 Words | 3 PagesThe poorly sorted nature of the conglomerates, considered with the inclusion of wood fragments in the older conglomerate members and the graded sandstones and mudstones throughout the formation suggest deposition occurred through successions of debris flows. Presence of volcanics in the lithic fragments further indicate volcanic activity in the process of sedimentation as well—as debris flows associated with lahars are the likely source of the slope failures. Deposition environment was moderate to deep marine, as mudstone deposits require low energy depositional environment, but the style of sedimentation indicate deposition was not on a continental shelf. This is further supported by inclusion of the large overturned clast from an older member within the formation. Cross-bedding, graded bedding, and scouring surfaces provide 3 lines of evidence establishing the northern contact of the formation as the original upward oriented surface.

Catastrophism is the idea that Earth has been affected in the past by sudden, short-lived, violent events, possibly worldwide in space. This view holds that the present is the key to the past, and that all things continue as they were from the beginning of the
Comparing The Chemical Reaction Between Pop Rocks And Soda Drink
298 Words | 2 PagesPop Rocks and soda have a very interesting chemical reaction with each other. Soda is a very pressurized drink that has carbon dioxide in it. Carbon dioxide is a pressurized chemical. When it is shaken, it fizzes, and causes pressure, and overflows releasing the carbon dioxide. It is similar to the Pop Rocks.
