YupRocks - Metamorphic Rocks Descriptions and Pictures

The study of metamorphic rock helps to understand the pattern of heat and pressure formed under the earth’s crust. Examples of Metamorphic rocks are Slate, Schist, Quartzite, Gneiss, Marble and many others. The process in which the metamorphic rocks are formed is known as ‘metamorphism’, meaning “change in form”.

Metamorphic rock - Wikipedia

Metamorphic rocks arise from the transformation of existing rock types, in a process called metamorphism, which means "change in form". The original rock is subjected to heat (temperatures greater than 150 to 200 °C) and pressure (100 megapascals (1,000 bar) or more), causing profound physical or chemical change.The protolith may be a sedimentary, igneous, or existing metamorphic rock.

Classification of Metamorphic Rocks - Geology In

Each of these will be discussed in turn, then we will summarize how metamorphic rocks are classified. Texture In metamorphic rocks individual minerals may or may not be bounded by crystal faces.

Metamorphic microstructures - Union College

Fault rocks are a special variety of metamorphic rock that is often overlooked. Fault rocks have a range of characteristics from brittle to ductile. Brittle faulting, foliation development, and grain size reduction tend to make faults weaker than surrounding rocks, a process known as strain-softening. That tends to restrict faults to narrow zones.

Rocks - Geology (U.S. National Park Service)

Rocks are divided into three basic types depending on how they were formed: Igneous, Sedimentary, and Metamorphic. How Rocks are Classified Natural objects, such as rocks and minerals, contribute to the beauty and wonderment of the National Parks and should be left, as they were found, so that others can experience a sense of discovery.

Metamorphic Rock Textures

The mineral constituents of foliated metamorphic rocks are oriented in a parallel or suhparallel arrangement. Foliated metamorphic rocks are generally associated with regional metamorphism. Four kinds of foliated textures arc recognized. In order of increasing metamorphic grade, these are slaty, phyllitic, schistose and gneissic.

Metamorphic rock Facts for Kids - Kiddle

A metamorphic rock is a type of rock which has been changed by extreme heat and pressure.Its name is from 'morph' (meaning form), and 'meta' (meaning change). The original rock gets heated (temperatures greater than 150 to 200 °C) and pressured (1500 bars).This causes profound physical and/or chemical change.
