Any gap in age of rock between rock layers is called an uncomformity. An unconformity is the contact between two layers representing a gap in the geologic record, usually from the erosion of the layers which would normally be expected to appear.

a SILL is an intrusion that is parallel to the strata.

What can cause an unconformity?
Unconformities occur when erosion wears away rock, or when rock deposits are never formed.

A gap in the geologic record formed when sedimentary rocks cover an eroded surface is called an?
A dis-conformity is an unconformity representing a period of erosion or lack of deposition in a sedimentary rock section.
What causes a gap in the geologic record?
Erosion of already deposited layers or a time span of non-deposition.
A break in the rock record deposition of sediment has been interrupted is referred to as a?
A gap in the geologic record of rock formations is called an uncomformity.
A common cause of gap in rock layers is what?
A gap in sedimentary layers is known as an unconformity, and occurs as a result of either erosion or a period of non-deposition.
What is unconformities?
unconformity (plural unconformities)(nonstandard) A lack of conformity.(geology) A gap in time in rock strata, where erosion occurs while deposition slows or stops.
What does uncomformity mean?
An unconformity is a gap in time of the rock record. In a stratigraphic column this is evidence that erosion has removed a portion of the natural deposition of sediment in an area. In a disconformity erosion takes place between sedimentary rocks that have not been otherwise modified. In an angular unconformity, previous bedding has been tilted from its original deposition and undergone erosion, and is topped by new sediment that is deposited horizontally on top of this tipped surface. In a nonconformity, huge amounts of erosion have exposed igneous or metamorphic basement rock and there is an igneous or metamorphic rock contacting sedimentary rock.
