Learn how to … If a great amount of pressure is exerted on the sedimentary rock, or it is heated, it may turn into a metamorphic rock. You just studied 25 terms! An example is Winnsboro Blue Granite – an igneous rock composed of the minerals quartz, feldspar and mica that is also the state stone of South Carolina. Categories of identification for the three main rock types. And with a fine-grained rock you need a microscope. Chalk. The primary basis for naming chemical and organic sedimentary rocks is their composition. includes a collection of known (identified in the visual bank) samples with reference properties. There is a sorting page for sorting the rocks by type. deposition. Compare your recorded observations with an identification chart in your textbook or other resource, OR consult this limited bank of identified sedimentary rocks. PROCEDURE First, take some time to familiarize yourself with the flow of the identification chart. Sedimentary rock identification is primarily based on composition. Saved by Costas C. 329. Organic sedimentary rocks form from the accumulation of plant or animal debris. A process that moves sediments by wind, water, and ice. cementation. With medium-grained rocks, you need a hand lens to see the grains separately. ! Sedimentary Rock Identification 1) Using the characteristics described below, fill in the table on your answer sheet for the nine (A-I) unknown sedimentary rocks. Introduction.
