Sedimentary Rocks Identification Lab Before you start this lab, watch the Sedimentary Rocks Part 1and Part 2 videos under Learning Activities. (Notes from this lecture are posted on the Study Guide for Exam 2 Edit From #33-#55 Highlighted in Yellow) The Laboratory about Sedimentary Rocks is from page 147 to page 181 in the Lab Manual. Objectives: Beable to describe, classify, and identify hand samples of sedimentary rocks Complete the Sedimentary Rocks Identification Table Read “A Practical Guide to Sedimentary Rock Identification” on pages 159 to 161. Where might this sediment have been deposited/precipitated? Use the information from lecture, Page 165 in your lab manual and Page 165 Old (below). What depositional environment could the rock be forming in today? The “Sedimentary Rock Field Notes” file is there to help with the Identification of the Sedimentary Rocks. Some of the information in this file is about using Hydrochloric Acid on the rocks. If you place one drop of dilute Hydrochloric Acid (HCl) on a rock that contains Calcite (CaCO3), then it will fizz and bubble (effervesce) because of the chemical reaction that takes place. If you place one drop of dilute Hydrochloric Acid (HCl) on Dolostone (CaMg(CO3)2), then it will fizz and bubble (effervesce) weakly because the chemical reaction is weaker.
