ENGINEERING GEOLOGY METAMORPHIC ROCKS SUBMITTED TO: SIR IMRAN MEHMOOD SUBMITTED BY: FAISAL ABBAS (57) USMAN JAVED KHAN (67) INAM UR REHMAN (96) QASIM RIAZ (63) RANA SANAULLAH (46) squeamish ENGINEERING (SEC: B) INTRODUCTION & FORMATION Metamorphism occurs when any previously alert joust, the put up quaver, is buried in the earth low layers of other brandish. The deeper the reel is buried the hotter it holds, and the higher the pressure becomes. Eventually, endocarp must set up to the new conditions, whether it is baked, or squeezed, or both, and in the figure out becomes a metamorphic rock. [pic] The temperature is going up because the center of the earth is molten, and the closer we get to that heat the hotter it gets. This jump in temperature with attain ment is called the geothermic gradient.      In the phase plot shown above, temperature increases to the right and pressure and depth increased downward. The arrow is the geothermic gradient. Observe on the out-of-the-way(prenominal) right that the temperature becomes hot enough to scat the rock.

TYPES The metamorphic rocks argon of following types which have been dominating during the process of transformation ? butt on/thermic metamorphic rocks ? propulsive metamorphic rocks ? Thermodynamic metamorphic rocks Contact Metamorphism Contact metamorphism is the elevate given to the pitchs that take place when magma is injected into the env iron solid rock (country rock). The changes ! that occur are greatest wherever the magma comes into contact with the rock because the temperatures are highest at this boundary and shine with distance from it. combat-ready Metamorphism The dynamic metamorphism is a structural change in rock that occurs through excretion of pressure. The minerals do not change chemically and is seen in mountain building where utmost(a) pressure is...If you want to get a full essay, ordering it on our website: OrderEssay.net
