Introducing Metamorphism [Paperback]

Metamorphic rocks are one of the three main types of rock. Originally comprising either igneous or sedimentary rocks, metamorphic rocks are the products of change by heat and pressure, often at great depths in the earth’s crust, into a completely new form. One of the classic examples of the result of a metamorphic process is the transformation of sedimentary mudstone into slate.Introducing Metamorphism provides a succinct introduction to metamorphism. Ian Sanders explains how and why rocks change during metamorphic processes. He discusses the role of water in metamorphism and describes the different types of metamorphic processes including contact, shock and high pressure metamorphism and metamorphism in an orogenic belt.Copiously illustrated and written for those who wish to gain a clear understanding of metamorphic processes, Introducing Metamorphism is designed to make the processes that led to the formation of these rocks intelligible to its readers. Technical terms are kept to a minimum and are explained in a glossary.Metamorphic rocks are the third great type of rock found in the lithosphere. Originally of other types these rocks have been changed mainly by heat and pressure into new forms. This introductory guide explains metamorphic processes and the resulting rocks.‘In summary, the author has succeeding in producing a text that provides a comprehensive description of metamorphism ranging from the simple fundamental definitions to complex metamorphic processes.It is superbly illustrated with, in particular, excellent photographs and microphotographs illustrating mineral textures, the relationship of minerals to structures and the relative development of minerals. In addition, there are many very clear and useful diagrams covering mineral types, their stability fields and their development under evolving metamorphic conditions, simplified facies maps, the relationship of minerals within triangular chemical diagrams, etc.This is a well-produced boló¾
