What are the methods for the production of slate formation?
② quadrant angle representation. In general, the direction of inclination, inclination and inclination, such as N65 ° W / 25 ° SW, is about 65 ° north west, inclination of 25 °
(Usually, the direction and tendency are in the default plane parallel to the ground) There are two ways to represent the formation:
① azimuth representation. Generally record the tendency and inclination, such as 205 ∠ 65, that is, the tendency of southwest 205 °, angle 65 °, the trend was NW295 ° or SE115 °.
