... and three shallow cores reveal that the uppermost part of the upper Pleistocene (Marine Isotope Stage 5e) Lucayan Formation at Red Bays, Andros Island, Great Bahama Bank, comprises a single, 6-m-thick upward-shallowing parasequence. Six radar packages (P1–P6) bounded by radar surfaces (S1–S6) have been...

... Stylophora spp. As the change from nonskeletal to skeletal limestones is relatively rapid and traceable for 40 km, it is used to define the base of a new formation, the Lucayan Limestone. The upper boundary of this formation is the limestone surface exposed on the Bahama Islands or covered by soft Holocene...

... the Lucayan Formation on the leeward margin indicates that skeletal sands (shallow slope) were deposited during pre-Lucayan time. This conclusion is confirmation that skeletal sands predominated across the entire Bank during pre-Lucayan time. Reef deposits are a major contributor to the progradation...

Engineering, intended to be positive, may have a serious negative impact, as for example the detrimental effect the Grand Lucayan Waterway had upon...

All synthetic platforms are then subject to burial to an arbitrary depth of 2 km, with compactional porosity and permeability reduction. We compare vertical...

... ~1 Kyr of sparse occupation by the native Lucayan people across the archipelago before Spanish contact in 1492, which devastated native populations to near zero by 1520 (Farnsworth 1996 ). This was followed by British colonization and establishment of African slave–based plantations by the late...

... basinal sediments buried the escarpment and the platform started to prograde (Orfento Formation, Supersequence 2). This platform expansion is coeval with the development of a basin-floor fan at the base of slope in the Gran Sasso area ( Figure 6 ). The progradation was halted by renewed emergence...
