1.FOLDS 2.FAULTS 3.JOINTS
FOLDS
Flat-lying sedimentary & volcanic rocks are often bent into a series of wave-like undulations.
2 MOST COMMON TYPES
» Anticline & Syncline
» Domes & Basins
FAULTS
are fractures in the crust along which appreciable displacement has occurred, on a scale from cm~km.
3 TYPES– Dip-slip Faults
– Strike-slip Faults
– Tensional & Compressional Forces
JOINTS most common rock structures are fractures. are fractures along which no appreciable
displacement has occurred.
2 TYPES
• Columnar Joints
• Sheeting
