The long axis of a strain ellipsoid is generally in the same direction as the strike of tension joints.

Both meridian and parallel of latitude will form an ellipse when the earth ellipsoid makes one turn.

The<br/>long axis of a strain ellipsoid is generally in the same direction as<br/>the strike of tension joints。(<br/>)

In<br/>a strain ellipsoid for rock deformation, the maximum strain axis is<br/>parallel to() A: the<br/>maximum flattening surface B: the<br/>maximum tensile surface C: the<br/>maximum stretching direction of minerals D: the<br/>maximum shearing surface
