Deep and wide shrinkage cracks and slickensides are developed in Vertisols due to the presence of shrink‐swell minerals like smectites. As a result of swelling of these minerals, vertical and horizontal shear stress pushes the clay mass upward forming parabolic thrust cones as cyclic horizons. A mathematical equation has been proposed for measuring the linear distance of these cyclic horizons taking into account the depth of occurrence of slickensides. This equation is an improvised, but useful, method to identify locations of microdepressions and microknolls required for better management of Vertisols.
