A sill is a relatively thin intrusion, which makes a table along bedding planes.

Well, then there's a squeeze through a bedding plane.

The long squeeze through the bedding plane had taxed his nerves.

There is a bedding plane, a seam, running just below the capsule.

What is any bedding plane if it is not a mini-unconformity?

If we really had continuous sedimentation then there would surely be no bedding planes at all.

But I still maintain that most bedding planes show evidence of a pause in sedimentation, if not actual erosion.

They are created by the wave driven erosion of cliffs along faults and bedding planes in the rock.

It is a complex maze of passageways, large and small, mostly developed along one or two major bedding planes.

Fortunately, the Burgess fossils do not usually lie on a single bedding plane.
