Geology Essay
Metamorphismis a change in the composition of a pre-existing stone caused by pressure, heat, and reaction to synthetic fluids. There XXX at least six XXXXXXXXX types of XXXXXXXXXXXX:XXXXXXX, XXXXXXXX, cataclastic, XXXXXXXXXXXX, burial, and shock. Some XX XXXXX are XXXXXX XXXX one XXXXXXX despite XXXXXX XXXXXXX XX XXXX it XXXXXXXX metamorphism.
XXXXXXXX XXXXXXXXXXXX is a deformation of distinctive XXXXXXXX (tectonic) XXXXXX XXXX form XXXXX based XX the immense pressure XXX XXXXXX XXXX XXXX a collision (XXXXXXX show XXXXX XX XXXXXXXXX or laminae). The rocks XXXX XXXX pushed XXXX the XXXXX towards the surface, XXXXXXX the crust; while the other XXXXX XXX XXXXX XXXXXX XXXXXXX levels into the Earth XXXX. XXX XXXXX XXXX become exposed to not XXXX higher XXXXXX XX pressure XXX higher amount of XXXX. If sedimentary rocks were XXXXXX towards XXX XXXXX’s core XXXX reach XX a XXXX XXXXXXXXXXX XX XXXX 300C, it XX considered asXXXXXX metamorphism. As a result, new XXXXXXXX form XXXX as Zeolites! XX addition, XXXXXX XXXX XXX exposed to XXXXXX XXXX XXXXXXXXXXX XXXXXX in XXX XXXXXXXXXXX or XXXXXXXXX XXX XX XXX rocks’ XXXXXXX minerals XX XXXXX asXXXXXXXXXXXXXXXX.
Alternatively,XXXXXXXXXXXX metamorphism XX XXXX ores (XXXXXXX basaltic) are XXXXXXXX by high temperatures XXX XXXXXXX XXXXXXXXX from XXXXXXXXXXXX XXXXXXXX.Contact XXXXXXXXXXXX XXXXXXX XXXX rocks have XXXX exposed to very XXXX heat XXXXXXXXXXXX XXXXXXXXXX XXXX XXX igneous XXXXXXXXXX. XXXXXXX XXXXXXXXXX (an XXXXX XXXXXX XX magma XXXXXXX that solidifies XXXXX slowly reaching XX XXX XXXXXXX) XX still XXXXXXXXXX by magma, so any XXXXX that are XXXX the XXXXX will change XXX minerals XX XXX XXXXX due XX intense heat. In XXXXXXXX, XXXXX XXX XXXX closest XX the magma XXXX higher grade XX minerals embedded XXXXXXX the XXXXX XXXX are XXXXXXX for XXX XXXXX diameter XXXX XXXXX grade minerals. When a XXXX has been XXXXXXX in a heat XXXXXXXXXXX XXXXXXX XXXX and XXXX is XXXXXXXXXX a low grade; anything XXXX XXXX is considered a XXXX XXXXX.
XXXXXX, there XXshock/impact metamorphism XXXcataclastic XXXXXXXXXXXX in which XXXX occur rarely.XXXXXXXXXXX XXXXXXXXXXXX happens XX a fault XXXX XXXX large land of XXXX shifts past each other and XXXXXXX XXXX XXXXXX those XXXXXXXX XXXXXXXXX. XXXXX that XXXXXXX XXXX XXXXXXXX are mostly crushed, XXX XXXX XXXXXXXX change.ShockXXXXXXXXXXXXXX when a XXXXXXXXX or an XXXXXX ore XXXXX XXXXX an XXXXXXX impact on the Earth’s surface. XXXX a XXXXX amount XX pressure XXXXX XXXX XXXXXXX with the Earth, it creates XXXXXXX XXXX XXX XXXXXXX XXXXXX called shock lamellae or shatter cones.
