Zhu Zhicheng et al. [China University of Geosciences] Strike and dip of a plane Trend & plunge of a line Pitch and pitch direction Relationship between true dip() and Apparent dip( or )
APPARENT DIPANGLE CALCULATION Equation β= atan tan(o)cos(6) B=apparent dip angle, a= true dip angle, 8=angle between true and apparent dip direction
Equation: = atan[tan()cos(d)] = apparent dip angle, = true dip angle, d = angle between true and apparent dip direction. d APPARENT DIP ANGLE CALCULATION
