 having uniform displacements, the spacing being uniform within each system but different for each system.

FIG. 52. Diagram showing the diverse courses of lines of equal displacement which are the result of two systems of equal 

 .faults intersecting at right angles but unequally spaced. 



From this simple case the variations and irregularities such as are usually met 

 in nature bring about endless changes. A few of these maj r be ideally deduced. 

 Fig. 51 illustrates a case of equal faulting in two systems which are at right angles,
