Un′con‐form″i‐ty, n. 1. Want of conformity; incongruity; inconsistency. South.
2. (Geol.) Want of parallelism between strata in contact.
☞ With some authors unconformity is equivalent to unconformability; but it is often used more broadly, for example, to include the case when the parallelism of strata once conformable has been disturbed by faulting and the like.
