Lens (geology)

The adjectives "lenticular" and "lentiform" are used to describe lens-like formations.

Lenticle is a synonym for lentil, but may also refer to a fragment of rock that is lens-shaped.

[2] A lentil may also refer a minor unit in a formation of rock, similar to a member but not generally spread out over a large geographical area.

[3] Lenticular bedding is a special form of rock interbedded mudrock and cross-laminated rippled sandstone.

The lenses or ripples in lenticular beds are discontinuous in all directions.
