Direction of the intersection line between the inclined rock stratum and the horizontal plane B. Trend C. Joint D. Angle between the rock stratum plane and the horizontal plane E. Intersection line
A. Direction of the intersection of the inclined rock plane with the horizontal plane B. Dip C. Joint
A. Direction of the intersection line between the inclined rock stratum and the horizontal plane B. Trend C. Joint D. Angle between the rock stratum and the horizontal plane
Three elements of occurrence: Strike: The line where the fault plane intersects the horizontal plane is called the strike line, and the direction in which this strike line extends is the strike of the fault plane. It indicates the direction in which the rock strata extend above the ground surface. Dip: The line on the fault plane that is perpendicular to the strike line is called the dip line or true dip line. The direction in which the plane tilts downward, as indicated by the projection of this line on the horizontal plane, is the dip of the fault. Angle of inclination: The angle between the true line of inclination on the rock layer’s plane and its projection on the horizontal plane is called the angle of inclination. It represents the angle between that fault plane and the horizontal plane in an upright section along the direction of the vertical fault plane.
The main parameters of stratigraphic attitude are (ABC). A. Direction of the intersection line between the inclined rock stratum and the horizontal plane B. Trend C. Joint D. Angle between the rock stratum plane and the horizontal plane E. Intersection line
