n: an unconformity in which formations above and below are not parallel. See unconformity.

An unconformity in which the beds below the unconformity dip at different angles than the beds above it.

adj: layered in parallel and unbroken rows of rock, indicating that no disturbance occurred during deposition of the rock. Compare unconformity.

a surface separating younger from older rocks with no indication of erosion or other disturbance.

n: 1. In geology, any sharp or welldefined boundary between two different bodies of rock. 2. A bedding plane or unconformity that separtaes formations.

the depth of the interface between the oil and water, oil and gas, or water and gas.

n: an interruption in sedimentation caused by erosion;the strata above and below the disconformity are parallel. See unconformity. Compare nonconformity.

a change in the formation that may have been caused by ancient erosional forces. Accounts for variances in formation tops in near-by offset wells in a formation with no pay inclination.

usually a crystalline unconformity on which a non-magnetic sedimentary rock sequence has been deposited.

n: a buried landscape in which sediments were deposited on an eroded surface of igneous or metamorphic rock. Compare unconformity.

an unconformity that separates profoundly different rock types, such as sedimentary rocks from metamorphic.

n: the degree of conformity to each other of measurements repeated under specified conditions, irrespective of whether they are close or far from the true value.

n: a map of the formations directly above an unconformity. Also called a worms-eye map.

abbr: unconformity;used in drilling reports.
