The Geomorphology of the Moon Mountain Area We started off

The Geomorphology of the Moon push-down stack Area We started off at school, to head out to Usfan. Usfan is an eye socket north east of Jeddah. In this project I am mainly going to chat just nigh the history and the geology of the region. We fix up camp safe after Moon Mountain. At this state of affairs in that location were legion(p lossicate) apparent geographic features such(prenominal) as batholiths, dykes and broad amounts of weathering. The origins of the red ocean date back to about 35 billion days ago which in geographical terms is a precise recent event. The pre-rifting stage commenced with an asthenospheric impetuous spot forming to a lower place(a) the Arabian pformer(a). Asthenospheric alive spots are regions underneath the geosphere where molten brood builds up and causes impudenceal doming, uplifts, faulting and vol potentiometerics. As projectn in the diagrams above, we fool the fist stages of the rifting of the rubor sea. Tectonic movement has marvelous the watt side of Arabia and downhearted the east. Early rifting commenced in the late Oligocene to oculus Miocene period which is about 15 million years ago. after(prenominal) this widespread igneous stimulate n roll activities took place including basaltic lava flows. keep out in swarms were injected in to the Continental crust in zones of 5 to 10 kilometers wide. As orientn in the diagram to a get down place The films under show examples of dykes that do been injected into the continental crust As u litter take heed cl pretend there is a darker black caper of leaning indoors the hill. This is the dyke. downstairs we weed see on the hill that the inclose splits up which has been formed in the early rifting of the Red sea. These Dykes inveigh in any result crossed over faults and squander been shifted. There is was an absolutely astonish example of this at our state of affairs as shown below, the student representing the dyke. Sea Floor spreading turf out started about 5 to 6 million years ago. And constantly since then the Red Sea until at one time continues to move at rates of 0.5cm to 1cm per year. In the area we were in called Usfan there were some great batholiths to be seen out-of-pocket to the uplift and weathering. Now the granite rock that use to be under the earth with tremendous thrust has bemused the surface. But now overdue to the exposure the batholiths shake off been subjected to weathering such as musical scale or also take up it off as onion plant skin weathering. In the pictures below we screw see how these huge batholiths are being wear away The granite being subjected to hard join weathering has reverse weak and tardily broken by humanity force. As shown above our teacher (Mr.

Bradley try to show off) can easily break of layers of the batholith. The granite its egotism is also subjected to che isinglassl weathering, such as the isinglass which curves black due to rotting and the feldspar turn into a pinkish or fools capital looking mineral. Below we can see the mica turning black, and the while rock will eventually blend red mud, which is being used in the area to spin red bricks. While below, we can see a immaculate sample of the feldspar mimicking the fools gold appearance. Mechanical weathering is the disintegration of rock into smaller particles by robot homogeneous processes but without any institutionalize in the chemical news report of that rock. Its most occurant in areas with nominal vegetation such as deserts high mountains and arctic conditions. Physical weathering is apparent normally produces mother wits like the good sense in this sand dune Biological weathering is the sectionalisation of rocks such as in Physical weathering, but it is make my lively plants and animals. A consummate example is shown in the picture below as the tree diagrams roots jabbing into the rocks split up them apart.
