Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

A paraconformity is an unconformity for which no evidence exists, true or false?

A	True
B	False
C	Either A or B
D	None of the above

Explanation:

Detailed explanation-1: -The significant age gap between the beds that contain ammonites and the beds that contain trilobites suggest the presence of an unconformity. So, a sudden change in fossil content can provide evidence for the presence of an unconformity in nature.

Detailed explanation-2: -A paraconformity is a type of unconformity in which the sedimentary layers above and below the unconformity are parallel, but there is no obvious erosional break between them. A break in sedimentation is indicated, for example, by fossil evidence. It is also called nondepositional unconformity or pseudoconformity.

Detailed explanation-3: -Disconformities are characterized by subaerial erosion features. This type of erosion may leave in the rock record channels and paleosols. A paraconformity is a type of disconformity where separation is a simple bedding plane with no apparent buried erosional surface.
