Foliated textures produced by shearing and breaking, such as in a fault zone or a meteor impact crater, are referred to as mylonitic. Pressure from the weight of overlying rocks or from stresses of mountain building rearranges the minerals in rocks into bands or rearranges the atoms of the minerals into new minerals. Zoom In . These rocks may break across, rather than around, mineral grains to produce a scaly surface on the specimen. Remember, if you know the rock, you know the past environment!

All metamorphic rocks are derived by the action of heat and/or pressure on pre-existing igneous, sedimentary, or metamorphic rocks. Foliated texture is further subdivided based on the presence or absence of pronounced color banding in the rock. After going over the Do Now and objective(s) for the day, the lesson begins by asking students to turn to the 'Scheme for Metamorphic Rock Identification' on the bottom of page 7 in their ESRT(s) (image also attached on the attached resource).

Heat from the intrusion of a dike or sill or flow can bake the adjoining rocks in a contact metamorphic zone. The amount of time, amount of pressure, and highness of temperature determine what types of metamorphic rocks are made. They're usually given 1-2 minutes to collectively explore the chart, identifying any words, phrases, or rock names that might stand out to them. The chart is read The mineral composition of the rock can be determined based on observations with a hand lens and if needed, physical or chemical tests. You will discover a number of the templates are absolutely free to use and others call for a premium account. For example, when you break granite apart, you get small pieces of quartz (clear), feldspar (pink or white), and mica (black). The kind of metamorphic rock made depends on the kind of original rock; for example, sandstone is turned to quartzite, shale is turned to slate, and limestone is turned to marble.

Metamorphic Rocks Metamorphic rocks form when existing rocks are exposed to intense heat and/or pressure inside the earth These intense conditions will alter the rocks, changing (morphing or recrystallizing) them into a new rock. When you split a rock into very small pieces, the pieces are different from each other. Rocks can be a mixture of different kinds of minerals, a mixture of many grains of the same kind of mineral, or a mixture of different grains of rocks. wikipedia, Many are downloadable.

Exploring Earth Final Project Spring 2007 . Igneous rock identification key. In this texture, the mineral crystals in the rock are aligned with each other. 16. NONFOLIATED rocks (granoblastic): little or no preferred mineral Other kinds of metamorphic rock are named for the kinds of minerals present, the size of the grains and other textures. Layered is also referred to as gneissic foliation. Metamorphism (meta = change, morph = form) happens when molten rock intrudes other rocks and bakes the contact zone where the molten rock touches the preexisting rock. Rocks without distinct alternating bands of light and dark minerals are described a nonlayered, whereas rocks with alternating bands of dark and light minerals are described as layered.

This is a continuation of lesson 1.10, in that it similarly examines the 'Scheme for Metamorphic Rock Identification' on page 7 of the ESRT (attached). As a result, nonfoliated rocks commonly appear massive and structureless, with only a few lines of impurities through the rock. on page 702 of the textbook to answer the questions below. Metamorphism also happens when rocks are buried deeply during the process of mountain building. There are two major textural groups in metamorphic rocks: Foliated and Non-Foliated.
