EVEG 2000 : Study Guide To Metamorphic Rocks
Document Summary
Metamorphic rocks-is a rock that forms from a preexisting rock. Metamorphism- is the solid-state recrystallization of pre-existing rocks due to changes in physical and chemical conditions. Metamorphic texture-is the way the grains in the rock have grown and interlocked. Metamorphic grade- is a scale of metamorphic intensity used to indicate the amount of metamorphic change that the rock has undergone. Questions: the processes that help to form metamorphic rocks are recrystallization, phase change, metamorphic raction, and pressure solution. He first made his observations in the latter half of the eighteenth century in ireland: the role of hydrothermal fluids is chemically breaking down minerals and accelerating metamorphic reactions. These fluids flow across or beneath the earth s surface and are deposited to form veins. mineral is what determines where metamorphism will occur: metamorphism occurs in all different types conditions. Depending on the: we classify metamorphic rocks through the study of the layers of the metamorphic rocks.
