Rock Classification Scheme Volume 1: igneous rocks; Volume 2: classification of metamorphic rocks. Igneous rocks (fiery rocks) are made when molten material inside or outside the earth cools and becomes solid. You need to know this number, because you need to know how many of the rocks that you are working with are Igneous Rocks. IGNEOUS ROCK IDENTIFICATION KEY..... 28 Igneous - glassy ... identity, refer to the mineral key or the rock classification charts. Part A- Identification of Igneous Rocks Classification of igneous rocks is based on texture (grain size) and mineral composition (often related to color). Use the classification chart (Table 1) to assign correct names to the lab specimens. Do not expect the classification and key to match up well. Note: An important key to classifying igneous rocks is their Environment of Formation.In other words, where did the rock originally solidified; from magma or lava. It is our hope that the samples and information will … 1.

Students are provided with both hand specimens and thin sections. They should be able to explain the differences between igneous, sedimentary, and metamorphic rocks. The diagram in Figure 3.16 can be used to help classify igneous rocks by their mineral composition. Name a very light-colored, glassy, extrusive rock with bubbles. Igneous rock - Igneous rock - Classification of plutonic rocks: A plutonic rock may be classified mineralogically based on the actual proportion of the various minerals of which it is composed (called the mode). Letters A, B, and C represent specific rocks in this classification scheme. This melted rock is called magma when it is inside the earth. Mineral identification worksheet answers. Mineral Identification Chart Link Doesn T Work But Chart Is This worksheet utilizes the scheme for igneous rock identification of the esrts and allows students to practice calculating the percentage of each mineral found in a some igneous rocks. 10 in depth questions - … Igneous Rocks. What name is applied to a coarse-grained, felsic igneous rock? Using your senses and the Scheme for Igneous Rock Identification found in your reference tables, you will be able to first classify then identify the environment of formation of a variety of different igneous rocks. Rock Classification Answer Key Vocabulary: classify, extrusive igneous rock, foliation, fossil, igneous rock, intrusive igneous rock, metamorphic rock, mineral, sedimentary rock, strata, texture Prior Knowledge Questions (Do these BEFORE using the Gizmo.) Most Igneous Rocks have a texture. The diversity of metamorphic rocks results from the combined effects of a range of tectonic and/or metamorphic processes acting on a wide range of protolilths (the original, pre-metamorphism rock). These are known as intrusive igneous rocks. Apr 5, 2015 - Two page worksheet where students identify the different types of igneous rocks. Samples come from the Wards Collections (which many schools have). Name a coarse-grained, dark-colored igneous rock. Deals heavifully with reading the Igneous Rock Scheme Chart.

Whatever your company planning goals, cash flow is the most crucial resource in the company, and managing money is the business purpose. (4) igneous rock that formed in a land environment Base your answers to question 22 on the Rock Classification Flowchart shown below. 1. Use the Scheme for Igneous Rock Identification in the Earth Science Reference Tables to answer the following questions about igneous rocks. II. The quiz will help you determine how many igneous rocks you should try to identify. Remember, rocks form the sentences and paragraphs of earth’s language. Students should understand what minerals are and how to identify them. Using the chart in their ESRT, they can identify the specific metamorphic rocks that are formed from particular sedimentary rock forms. 3.4 Classification of Igneous Rocks As has already been described, igneous rocks are classified into four categories, based on either their chemistry or their mineral composition: felsic, intermediate, mafic, and ultramafic. This is the amount of Plagioclase Feldspar in the rock. 10 in depth questions - great for HS Earth Science class. Rocks and the Reference Tables Use the rock identification charts on pages 6-7 of the Earth Science Reference Tables to answer the following questions Scheme for Sedimentary Rock Identification 15. I explain that the symbols are types of igneous or sedimentary rocks, but when magma intrudes into sedimentary rock layers, it's capable of "baking" the rock, ultimately turning it into a type of metamorphic rock. A key is just a method of identification, and subdivides objects only for that purpose. Describe the differences in how these groups of rocks formed. 1. For example, most such schemes show that a dacite is a rock that contains small amounts of quartz, somewhat larger amounts of sanidine or alkali feldspar, plagioclase, biotite, and hornblende, In all the years I have been looking at igneous rocks (since about the mid-cretaceous) I have yet to see a dacite that contains alkali feldspar. the key: if you know the rock, you know the past environment! 4. In this key, clastic, chemical and biochemical rocks are often intermixed. Identify the rocks you have studied using the rock identification chart.

Finally, they should be able to identify mineral and rock samples using the Earth Science Reference Tables and the physical characteristics of the samples. Rocks Flow Chart Scheme for Igneous Rock Identification ESRT The magma cools slowly inside the Earth, the resulting igneous rock will have larger, more visible crystals. Scheme for Igneous Rock Identification Overview: Igneous rocks form as molten rock (lava/magma) cools and solidifies. This project is intended to introduce students to the IUGS rock classification scheme. 2. The rock names are color coded to their origin, however, according to the following scheme. Name the three major groups of sedimentary rocks (refer to their textures). Interactive Rock Identification chart answer key. In this lab, we will explore the basic classification scheme for igneous rocks based on texture and silica Two page worksheet where students identify the different types of igneous rocks. If this solidification process occurs inside the Earth, the magma will form intrusive igneous rocks. 6 IGNEOUS ROCKS SECTION IGNEOUS ROCKS REVIEW Directions: Using your Igneous Rock Identification Scheme from your ESRT’s answer the following questions. These extrusive igneous rocks may also have a vesicular texture, containing trapped air pockets. 3.
