Title: J.O.I.D.E.S. Ocean Drilling on Continental Margin off Florida: ABSTRACT

Author(s): Robert Gerard

Article Type: Meeting abstract

Abstract:

Most of the Tertiary section was sampled in six core holes drilled along a transect across the continental shelf, slope, and Blake plateau east of Jacksonville, Florida. Water depths at the drill sites ranged from 25 to 1,032 meters and penetrations into the bottom from 120 to 320 meters. Continuous coring was attempted at most of the sites, using a wire-line core barrel. Core recovery averaged 36 per cent overall, with best recovery (46%) in the soft formations of silt and clay and poorest recovery (22%) in hard layers of chert and dolomite. A generalized stratigraphic cross section, drawn from the coring results, reveals that the continental margin is a wedge-shaped constructional feature which becomes thinner seaward.
