GENERAL GEOLOGY

Detailed explanation-1: -In terms of faulting, compressive stress produces reverse faults, tensional stress produces normal faults, and shear stress produces transform faults .

Detailed explanation-2: -Normal faults result from tensional forces when rocks are displaced away from each other. Reverse faults results of compressional forces when rocks are displaced towards each other. Strike-slip or transform faults results from either compressional or extensional forces when rocks slip parallell to each other.

Detailed explanation-3: -There are three causes to faults: tensional stress, compressional stress, and shear stress.

Detailed explanation-4: -Rock responds to stress depending on pressure, temperature, or minerals. Rock deforms by three forms of deformation: elastic, ductile, brittle. Direction of stress determines fault types: tension stretches, compression shortens, shearing pushes horizontally. fault types also relate to the three plate boundary types.

Detailed explanation-5: -reverse (thrust) fault-a dip-slip fault in which the upper block, above the fault plane, moves up and over the lower block. This type of faulting is common in areas of compression, such as regions where one plate is being subducted under another as in Japan.
