Dictionary:Fig F-15

FIG. F-15. A flower structure results when there is a component of convergence on a strike-slip fault, sometimes called an upthrust structure. Flower structures usually involve asymmetry. A component of divergence produces a negative flower structure (not shown) with the center dropped down to accommodate the extra space. Bends in a strike-slip fault may produce positive and negative flowers at different places (see Figure F-4). (From Lowell, 1985, 63.)
