GENERAL GEOLOGY

Detailed explanation-1: -law of superposition, a major principle of stratigraphy stating that within a sequence of layers of sedimentary rock, the oldest layer is at the base and that the layers are progressively younger with ascending order in the sequence.

Detailed explanation-2: -The law of superposition states that in an undeformed sequence of sedimentary rocks, each bed is older than the one above it and younger than the one below it. The principle of original horizontality means that layers of sediment are generally deposited in a horizontal position.

Detailed explanation-3: -The law of superposition simply states that for non-deformed geologic strata, “sedimentary layers are deposited in a time sequence, with the oldest on the bottom and the youngest on the top”.

Detailed explanation-4: -(a) Principle of superposition: In a succession of undeformed strata, the oldest stratum lies on the bottom with successively younger ones above.

Detailed explanation-5: -The Law of Superposition says that within the layers of sedimentary rock, the youngest layer is at the top. As you go further, each layer below is older.
