Lab 14 – Strain Analysis Information to do this lab is available in the lab book as well as the lecture slides for ch. 4 Assignment: Problem 14.1 Problem 14.2: Use the handout showing oolites. Use the spreadsheet below to record your measurements. You can also enter formulas to automatically calculate most of the parameters. a. Measure the long and short axes of all the possible oolites (principal strains). Measure the azimuth of the long axes assuming North is at the top of the photo b. Assume that the area of the oolites did not change during deformation and calculate the diameter of the original circular oolite for each of the deformed oolites (area of ellipse = pi * radius1 * radius2; area of circle = pi * radius 2 ). c. For each oolite calculate engineering strain, stretch, and quadratic elongation of the principle strains. d. Find the average value of the principal quadratic elongations for the measured oolites. e. Plot a Mohr diagram of strain using your average values.
