flower structure A series of convexupward thrust or reverse faults found in transpressional strike-slip zones. On seismic sections the appearance of the structure is reminiscent of the petals of a flower or the leaves of a palm tree, hence the analogy. Such structures are important in oil exploration as they indicate strikeslip movements and therefore the possible development of pull-apart basins, and also provide potential areas for oil accumulation.
