    In case of Normal Fault or, Dextral faulting the final pattern will be as shown in the picture below. Sinistral Fault and reverse Fault will produce common pattern (shown in question); Dextral Fault and normal fault will produce same pattern (shown below in figure). Sinistral fault and normal fault will never produce the same pattern in this case.

    Answer: Reverse or Sinistral fault As you can see that the northern block (Hanging wall) is showing that the stratal position has shifted towards left. This can occur in two conditions mentioned below: 1. Sinistral fault: Normally as a result of strike slip Sinistral faulting this pattern can come out. 2. Reverse Fault: The beds are dipping towards west. Upthrowing of Northern block (Hanging wall) and subsequent erosion of elevated part in northern block will create the same pattern as shown in the diagram.
