Determination of Paleotectonic Principal Stress Direction, Including Analysis of Joints by Optical Diffraction

Details

• Description:
  A study of joints in Marathon County, Wisconsin, was made to determine the orientation of regional paleotectonic stresses and to develop a method of using optical diffraction analysis (oda) in studying joint orientations and spacings. Standard geologic and petrofabric techniques employing the use of a geologic compass and a schmidt net were used in gathering, describing, and reducing joint orientation data. Analysis of selected outcrops with oda indicates that oda can be applied to study both joint orientations and spacings. Oda is shown to be a rapid method that can be used to complement standard petrofabric techniques, especially in the study of joint spacings. [Description provided by NIOSH]
