Classification of metamorphic rocks based on texture. materials. The texture can be foliated or nonfoliated. Non-foliated rocks form when pressure is uniform, or near the surface where pressure is very low. spotted hornfels, or spotted phyllite, Some gneisses have large eye-shaped grains, Other modifying terms that we may want to add as, Ortho- a prefix indicating an igneous parent, and, Para- a prefix indicating a sedimentary parent, The terms are used only when they serve to. Igneous Rocks. Minerals are: Naturally occurring Inorganic Solid Definite chemical ... - Chapter 2. Foliated metamorphic rock. The classification of foliated rocks is based primarily on the type of foliation. Foliated Metamorphic Rocks: i. Metamorphic reactions. In-depth video about rock cycle and types of rocks. Igneous Rocks PPT | Presentation | PDF: There are 3 nice classes of rocks, igneous, sedimentary and metamorphic, and most of the time, they are easy to inform apart.They’re all connected to the endless rock cycle, moving from one type to a different and dynamic form, texture and even chemical composition of the method. to the appropriate root as "granite migmatite," "monzonite injection migmatite," In the chart below notice how each of the first three rocks become the parent rock for the next. Lg: identify the steps of the rock cycle. Select a rock, and take the appropriate path below to classify the rock. When free from decomposed minerals and micas, these rocks also form excellent building stones. Classification – Metamorphic rocks Foliated Metamorphic Rocks (structural terms/names) Types of foliations a. Compositional layering on less than cm scale b. Caslon free download. Classification of metamorphic rocks. • Describe how metamorphic rocks are produced by the action of heat, pressure, and fluids on preexisting parent rocks over the course of time. #1. - Formation of Sedimentary Rocks Two processes that cause lithification. - Chapter 10: Metamorphism, Metamorphic Rocks, and Hydrothermal Rocks How Do Metamorphic Rocks Form? Granulite a high grade rock of pelitic, mafic, Migmatite a composite silicate rock that is, Porphyroblastic means that a metamorphic rock has, Some porphyroblasts, particularly in low-grade, e.g. This PowerPoint details the three types of rocks, sedimentary, igneous, and metamorphic. Foliated metamorphic rocks appeared banded or layered. and "cataclasite" if fine grained. Metamorphic Rocks and Minerals •Sometimes rock are subject to pressure and heat but do not melt. The texture can be foliated or nonfoliated. The kinds of rocks that can be expected to form at different metamorphic grades from various parent rocks are listed in Table 7.1. For this reason, serpentine appears both on this chart and on the igneous Grain size variation e. Preferred orientation of platy minerals in matrix without preferred orientation f. As can be noted from the chart, naming a metamorphic rock consists chiefly Determine if the following rock samples are foliated or non-foliated: Amphibolite Quartzite Phyllite Foliated Be sure to complete your “Types of Rocks” notes as you view this presentation. 8. Many of them are also animated. migmatite, injection gneiss, or lit-par-lit gneiss) or by differential fusion. Scapolite, cordierite, feldspars. important and if present should be included in the rock name regardless of their Regional Metamorphism – Extreme pressure, occurs deep below rock formations or where Earth’s crust collides. Quartz. Classification Metamorphic rocks are classified in … Made for Y3 pupils for Rocks and Soils science topic, this gives an overview of what rocks are and breaks down the meaning of igneous, sedimentary and metamorphic rocks.

Slates are characterized by the ‘presence of numerous closely- spaced parallel planes of […] Schist: metamorphic rocks in which the foliated minerals are coarse enough to see easily in hand specimen. do not differ substantially from the igneous processes forming migmatite, features, the rock is called "crush breccia" if coarse grained ADVERTISEMENTS: Metamorphic rocks are classified on the basis of foliation into the following types: 1. ... Metamorphic rocks are made from other rocks. These rocks will havestripes or planes that theywill break easily along. • Recognize the different types of metamorphism, the processes • Restate how metamorphic rocks relate to the two other rock groups (sedimentary and igneous). Scolding. Practice. * Serpentine is a product of hydrothermal alteration which some authorities Or use it to upload your own PowerPoint slides so you can share them with your teachers, class, students, bosses, employees, customers, potential investors or the world. Ppt. Metamorphic rocks Metamorphic rocks are the result of the transformation of a pre-existing rock type, the protolith, in a process called metamorphism, which means "change in form". Dolomite, calcite. % Progress . consider to be an igneous process and others a metamorphic process. 1 to the rock; it differs from schist in that grains are too small for megascopic Staurolite, Glaucophane, Anthophyllite, Pyrophyllite, Chloritoid, Actinolite, Or use it to find and download high-quality how-to PowerPoint ppt presentations with illustrated or animated slides that will teach you how to do something new, also for free. This indicates how strong in your memory this concept is. from slate in that crystallization of micaeous minerals imparts a sheen Unsanctioned Anticlines Supplementation. Quartz Porphyry Gneiss Types of Metamorphism Contact Metamorphism - Rocks heated (changed) by touching or being near magma. If there are no conspicuous directional As with igneous and sedimentary rocks, metamorphic rocks are classified on the basis of texture(grain size, shape, orientation) and mineral composition. These rocks form DEEP underground! FOLIATED METAMORPHIC ROCKS. Sedimentary rocks represent less than 5 per cent of the Earth's crust but 75 per cent of the Earth's land surface.
