|---|---|---|---|---|
100What is Most commonly formed by the upfolding, or arching, of rock layers.
Anticline
|
100A fracture which has shown no sign of significant displacement.
What is a joint

100A dip slip fault is know as what?
Faults in which the movement is primarily parallel to the inclination, or dip, of the fault surface.
