APPARATUS AND METHODS FOR MEASURING STRIKE AND DIP, TREND AND PLUNGE, BEARINGS, AND INCLINATION

摘要

An apparatus and methodology for measuring strike and dip of a plane, trend and plunge of a line, directional bearing in the horizontal plane, and angle of inclination in the vertical plane. More specifically, the present invention relates to a compass adapted to measure geological features using single compass configurations for each type of measurement. The compass includes a base, a hinge assembly rotatably interconnected to the base, and a lid rotatably interconnected to the hinge assembly. The lid is operable to rotate around both a major axis and a minor axis of the compass. A sight tube is positioned in a hollow bore of the hinge assembly and is operable to sight directional bearings.
