SEISMICALLY INDUCED DEFORMATIONAL STRUCTURES (SEISMITES) FROM THE MID-LATE HOLOCENE TERRACES, LOWER MAHI VALLEY, GUJARAT

Seismically induced deformational structures from the lower Mahi valle y are reported. These include injected liquefied sand, contorted lamin ations, load structures, overturned small-scale folds and convolutions , syn-sedimentary microfaults and pseudonodules. The structures are si milar to the seismically-induced deformation structures reported elsew here and conform to the criteria for relating them to seismic events. Radiocarbon dating of the two organic rich clay layers suggest the def ormation is related to a Late Holocene seismic event that took place b etween 3320+/-90 and 2850+/-90 yrs. B.P.
