Title:

Processed multichannel seismic data in the Venezuelan Basin and over the Beata Ridge, acquired during the R/V Maurice Ewing survey EW9501 (1995)

Abstract:

This cruise collected data in the Venezuelan Basin and over the Beata Ridge. The cruise had multiple purposes. Venezuela Basin: 1) Define the rough/smooth basement boundary better and examine the spatial and temporal relationship between the different crustal types. 2) Ascertain the crustal velocity structure. 3) Determine crustal thickness variations acrooss the rough/smooth boundary. 4) Image Moho, sub B, and Cretaceous to early Tertiary sediment reflectors. 5) Examine the link between the observed magnetic lineations and structural lineations. Beata Ridge: 1) Determine if crustal thickness variations can explain the differential topography between Beata Ridge and the Venezuelan and Columbian Basins. 2) Determine if additional deformation affected the region due to differential plate motion. 3) Ascertain whether the additional deformation and the resulting topography was due to tensional or compressional forces. 4) Address the history of the relative motion of the Caribbean plate and discern whether the azimuthal and deformation data can be better explained by one or two plates for the Caribbean region by determining the deformational history of the Beata Ridge.
