| A megaflap, or an overturned, folded, sedimentary-basin edge, is a classic feature of salt-controlled basins, formed during the inception of salt allochthony. To illustrate the relative importance of the balance between salt and sediment inputs, basin rheology, and tectonism resulting from basin interactions in the development of megaflaps, a set of analog experiments were performed in a computed tomography scanner. Sediments are modeled using both granular material and a mix of granular and viscous material and salt as purely viscous material. Uneven sedimentary loading and associated salt flow localize primary minibasins, which then migrate and expand laterally until sufficient thickness is reached to pin the downbuilding phase. The encasement of... |
