In a(n) __________ the erosional contact represents missing rock strata and separates sedimentary beds that are parallel.

Question

Quizplus · Accepted Answer

A disconformity is an erosional contact that separates parallel sedimentary beds but is not indicative of missing rock strata. A basal conglomerate is a layer of mixed sedimentary material that sits at the base of a sedimentary sequence, and is not necessarily indicative of missing rock strata. A nonconformity is an erosional contact that separates older igneous or metamorphic rock from younger sedimentary rock, and is not parallel. A boundary layer is not a term used in geology. An angular unconformity is an erosional contact that represents missing rock strata and separates non-parallel sedimentary beds. Therefore, the best choice for this statement is option A, disconformity.
