TYPES OF DEFORMATION

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
