Flame structure
Encyclopedia
A flame structure is a type of soft-sediment deformation that forms in unlithified sediments. The weight of an overlying bed
forces an underlying bed to push up through the overlying bed, generally when both strata are saturated with water. The resulting pattern (in cross section) may resemble flame
s.
The structures occur under pressure; they are often triggered by earthquakes of magnitude
> 6, which can initiate flaming in large (hundreds to thousands of square kilometres) areas, but can also be caused by the repeated pounding of waves.
