Unformatted text preview: Creates faults. Fault break in rock along which movement occurs. Dip-slip fault all motion is parallel to dip of fault plane. Normal fault hanging wall goes down. Reverse fault hanging wall goes up relative to foot wall and fault dip >45 Thrust fault hanging wall goes up relative to foot wall and fault dip <45 Horst Graben Strike-slip fault all motion is parallel to strike of fault Fault is usually vertical, so cannot determine foot wall/hanging wall. Named by looking across fault to see what direction other side is moving Left-lateral strike-slip fault the other side of the fault moves left Right-lateral strike-slip fault the other side of the fault moves right Oblique-slip fault motion is diagonal Sometimes rocks break but no movement occurs. Creates fractures. If a geometric pattern is created, fracture system is called joint system. Foot wall Hanging wall...
