Rocks: Igneous, Metamorphic and Sedimentary Rocks hold the history of the earth and the materials that will be used to build its future. Metamorphic rock is classified by texture and composition. Granulite: banding due to elongated quartz or feldspar grains. HPHE diversity in mineral composition of metamorphic rocks can be regarded as the resultant of two independent variables, first of the ultimate composition of the rocks, and secondly of the grade of metamorphism, or the … At the end of this lecture, you should be able to: (a). The major types of foliated metamorphic rocks include slate, schist, gneiss, and mylonite; important nonfoliated (or granular) rocks include quartzite, marble, hornfels, greenstone, and granulite.They are distinguished by their textures and secondarily by their compositions. - Formation of Sedimentary Rocks Two processes that cause lithification. Igneous Rock Igneous rocks are formed by magma and lava as it cools. - Chapter 5: Sandstone and Conglomerates Terrigenous From the Earth Terrigenous clastic sedimentary rocks are composed of clasts of pre-existing rocks and minerals. 7.2 Classification of Metamorphic Rocks There are two main types of metamorphic rocks: those that are foliated because they have formed in an environment with either directed pressure or shear stress, and those that are not foliated because they have formed in an environment without directed pressure or relatively near the surface with very little pressure at all. to the appropriate root as "granite migmatite," "monzonite injection migmatite," Graphite, Chondrodite, Scapolite. In each of the sections, you will find brief descriptions of TEXTURES and MINERAL COMPOSITIONS, and a classification chart based on these characteristics. All rocks can be transformed into other rock types Rocks are divided into 3 categories Igneous- crystalline- forms as liquid cools Metamorphic- crystalline-forms as rocks are heated and squeezed Sedimentary- non-crystalline- smaller pieces or chemicals from other rocks Magma • molten rock … Explains that metamorphic rocks are classified on the basis of texture (grain size, shape, orientation) and mineral composition. Clio's. Metamorphic Rock Classification. Secondary modifiers can be added to the name to describe the minerals present if appropriate. Cataclasite (kat-a-CLAY-site) is a fine-grained breccia produced by grinding rocks into … Igneous Rocks. Many of them are also animated. Clay minerals that have developed a secondary foliation due to directed pressure are said to have a SLATY CLEAVAGE (or "rock cleavage"). - Title: Chapter 8: Major Elements Author: Chuck Description: Most s are from your text, kindly provided online by Prof. Winter and Prentice Hall.Modifications by ... - Chapter 21: Metamorphism Rocks as chemical systems (Ch.

This is an exothermic process (it loses heat) and involves a phase change from the liquid to the solid state. Method #2 for plotting a point with the components: 70% X, 20% Y, and 10% Z on triangular diagrams. to the rock; it differs from schist in that grains are too small for megascopic due to pressure. % Progress . Types of Metamorphism Contact Metamorphism - Rocks heated (changed) by touching or being near magma. Phyllonite: a phyllite owing its fine grain to mylonitization, Rhyolite Gneiss irregular structure produced by intimate mixing of metamorphic and magmatic 3 types of rocks. Give an account of sediment erosion and transport (c). Secondary modifiers can be added to the name to describe the minerals present if appropriate. Metamorphic Rocks •Heat and pressure change rocks –The original rock is called the parent rock –The new rock formed is called the metamorphic rock –Heat and pressure change the structure of the parent rock and their minerals recrystallize The rock has split from bedrock along this foliation plane, and you can see that other weaknesses are present in the same orientation. The kinds of rocks that can be expected to form at different metamorphic grades from various parent rocks are listed in Table 7.1. Knowing the differences between these 3 types of rocks allows us to learn about Earths past.. Igneous Rocks - Formation Igneous Rocks are formed by melting, cooling, and crystallization of other rocks. Classification of metamorphic rocks. Foliated metamorphic rocks appeared banded or layered. They are all artistically enhanced with visually stunning color, shadow and lighting effects. Non-foliated metamorphic rocks do not have aligned mineral crystals. By C. E. TILLEY. TY - JOUR.
