Metamorphic facies

A metamorphic facies is a set of metamorphic mineral assemblages that were formed under similar pressures and temperatures.‎ The assemblage is typical of what is formed in conditions corresponding to an area on the two dimensional graph of temperature vs.‎ pressure.‎ Rocks which contain certain minerals can therefore be linked to certain tectonic settings, times and places in the geological history of the area.‎ The boundaries between facies are wide because they are gradational and approximate.‎ The area on the

Rocks Minerals : Identifying Types of Rocks

The three types of rocks are igneous, formed from molten rock, sedimentary, formed from the elements of an existing rock, and metamorphic, formed by a change in heat or pressure.‎ Identify the three different types of rocks with information from a geology professor in this free video on rocks.‎ Expert: Jeffrey K.‎ Wagner Bio: Jeffrey K.‎ Wagner is an associate professor of astronomy and geology.‎ He has been a faculty member of Bowling Green State University Firelands since 1981.‎ Filmmaker: Bradley Walton

Metamorphic Rock Experiment

Start with 3 clay balls of different colors.‎ Roll them together into one ball.‎ Smash the ball flat like a fat pancake.‎ Stand the pancake on its edge and then smash the clay flat again.‎ Cut the clay into 4 sections.‎ Students will look at the cut edges to see how the heat and pressure have made the colors stick together just like the minerals in metamorphic rocks stick together after being subjected to the heat and pressure deep in the earth.‎
