Unconformity \Un`con*form"i*ty\, n.
1. Want of conformity; incongruity; inconsistency. --South.
[1913 Webster]
2. (Geol.) Want of parallelism between strata in contact.
[1913 Webster]
Note: 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.
