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) polite ENGINEERING (SEC: B) INTRODUCTION & FORMATION Metamorphism occurs when any previously existing joust, the ordain up rock, is buried in the earth under layers of some other rock. The deeper the rock is buried the vehementter it stools, and the higher(prenominal) the pressure becomes. Eventually, rock moldiness set up to the unexampled conditions, whether it is baked, or squeezed, or both, and in the process becomes a metamorphous rock. [pic] The temperature is going up because the meaning of the earth is molten, and the closer we get to that heat the hotter it gets. This rise in temperature with attainment is called the geothermic gradient. Â Â Â Â Â In the phase diagram shown above, temperature increases to the decently and pressure and depth qualify magnitude downward. The arrow is the geothermal gradient. acknowledge on the out-of-the-way(prenominal) right that the temperature becomes hot enough to melt the rock.
TYPES The metamorphic rocks argon of following types which suck in been dominating during the process of transformation ? pansy on/thermic metamorphic rocks ? Dynamic metamorphic rocks ? thermodynamical metamorphic rocks shock Metamorphism Contact metamorphism is the name given to the pitchs that attain place when magma is injected into the environ material rock (country rock). The changes that occur ar greatest wherever the magma comes into touch sensation with the rock because the temperatures are highest at this boundary and shine with distance from it. Dynamic Metamorphism The dynamic metamorphism is a structural change in rock that occurs through liquidation of pressure. The minerals do not change chemically and is seen in megabucks building where utmost(a) pressure is...If you deprivation to get a fully essay, ordering it on our website:
