• Resumen

  • Analyses of gravity, magnetic and seismic data in southeastern Bahamas provide clear evidence for the presence of a Jurassic salt diaper at a depth of 5000 m. To date, salt diapirism has not yet been identified in the Bahamas. The deduced feature is adjacent to a deep basin, has a drainage area of over 9000 km2 and appears to be part of a Triassic-Jurassic syn-rift that extends 800 km southeast from Florida’s Sunniland Trend.
