GENERAL GEOLOGY

Detailed explanation-1: -The Law of Lateral Continuity suggests that all rock layers are laterally continuous and may be broken up or displaced by later events. This can happen when a river or stream erodes a portion of the rock layers. This can also happen when faulting occurs.

Detailed explanation-2: -RELATIVE AGE OF ROCKS Look at the Grand Canyon in Figure. It’s a good example of lateral continuity. You can clearly see the same rock layers on opposite sides of the canyon. The matching rock layers were deposited at the same time, so they are the same age.

Detailed explanation-3: -3) The principle of original lateral continuity that states that sedimentary layers are originally deposited as laterally continuous sheets that naturally terminate against basin margins or barriers or which grade into other sedimentary layers.

Detailed explanation-4: -Principle of Original Horizontality, states that sediments are deposited in flat, horizontal layers. Sedimentary particles settling under the influence of gravity in a body of water will deposit horizontal layer of sediment.
