GEOL 1301 Lab 07 Geologic Structures and Maps In this lab, you will learn about geologic structures and how to read and work with a geologic map. Please complete the attached worksheets and submit them in Canvas. Important notice: In order to successfully complete the lab, please review the following concepts and terms in your textbook and on the websites listed below. Terms and Concepts: ● Strike and dip ● Normal fault, reverse fault, strike-slip fault ● Hanging wall, footwall ● Anticline and syncline ● Geologic map ● Geologic profile Helpful Websites: http://en.wikipedia.org/wiki/Strike_and_dip http://commons.wvc.edu/rdawes/basics/structures.html 1
Geologic Structures Below you find some images of models of geologic structures numbered from 1 to 4. Name the structure and describe what happened in each case (e.g. compression or extension, how did the rocks move relative to each other, etc. 1) 2) 3) 4) Model # Type of Geologic Structure Represented What happened? 1 Reverse and thrust rocks hanging on to the wall of other rocks thus depicting compression 2 folding the bending of rocks with no cracks or fractures 3 strike and slip faulting the lateral slide of rock causing lateral displacement 4 normal fault the extension of rock as one side goes down the other comes up 2
Use the image below to answer the following questions: a) What is the strike and approximate dip of the rock layers? the strike of the rock layers in the image are going in the north-south direction, the dip of the rock layers are approximately 30 to 40 deg.to the east. b) Draw the map symbol that you would use to show strike and dip for these layers. the symbol used to demonstrate the strike and dip layers looks like a T, with the long side representing the strike and the horizontal short side representing the dip. This is demonstrated in the image above as well. 3
