Flat slab subduction - Wikipedia
Flat slab subduction is characterized by a low subduction angle (<30 degrees to horizontal) beyond the seismogenic layer and a resumption of normal subduction far from the trench. [1] A slab refers to the subducting lower plate.
Locating the Laramide Flat Slab - University of Colorado Boulder
Flat slab subduction is the dramatic shallowing of the angle of subduction between two tectonic plates. In normal subduction zones the angle of subduction is on the order of 30 degrees.
Slab (geology) - Wikipedia
Slabs experiencing low angle (less than 30 degrees) subduction is considered flat-slab, primarily in southern China and the western United States. [11] [12] Marianas Trench is an example of a deep slab, thereby creating the deepest trench in the world established by a steep slab angle. [13]

Mar 31, 2021 · A trim saw has a small, thin blade, that is made for cutting small stones into smaller chunks, or for creating a flat edge for a cabochon. Hi-Tech’s Diamond Trim Saw is a good starter option. A slab saw has a larger and thicker blade, making it suitable for trimming down rough rock slabs, or large stones that won’t fit into a trim saw.
