Metamorphism and metamorphic facies chapter 16 ,introduction. metamorphism is the sum of all changes that take place in a rock as a result of changes in the rocks environment; that is, changes in temperature, pressure and composition of fluids. the changes in the rock may be textural, mineralogical, chemical, or isotopic. these changes proceed at varying rates, so time is an important factor in metamorphism.

Geology Petrology Course

this course is a basic to advance introduction for the undergraduate students pursuing b.sc. geology engineering graduate for civil and mining. the term petrology comes from the ancient greek word petra rock and logos explanation that means the study of rocks and the ir processes of origin. this course deals with the naturally occurring rocks in field as well as laboratory petrology. greenschist, as a rock type, is defined by the presence of the minerals chlorite and actinolite and may contain albite or epidote.greenschist often has a lepidoblastic, nematoblastic or schistose texture defined primarily by chlorite and actinolite. greenschists often have some foliation resulting in mineral alignment, especially of chlorite and actinolite.
