(geology)
A sedimentary structure characterized by shingling of pebbles all inclined in the same direction with the upper edge of each leaning downstream or toward the sea. Also known as shingle structure.
Tabular masses that overlap one another and are inclined in the same direction. Also known as schuppen structure; shingle-block structure.

Imbricate Structure

 

a tectonic structure characterized by relatively thin and elongated rock sheets that overlap one another. The thickness of the rock sheets ranges from a few meters to a few hundred meters. Imbricate structures are usually found in series, forming groups of closely spaced folds, low-angle thrust faults, or fault-folds. In folded regions, they form imbricated fault zones. The amplitude of displacement may reach several kilometers but is usually not greater than a few hundred meters.
