Abstract

Change in the character of acoustic basement within the Mesozoic (Keathley) magnetic anomaly. South of Bermuda, the boundary is well defined and nearly isochronous, corresponding to anomaly M-12 or M-13 ( approximately 128 m.y. B.P.). North of Bermuda the boundary is diachronous and more transitional, with the change in basement relief occurring in a zone between anomaly M-21 and M-16-age crust (132 to 142 m.y. B.P.).--Modified journal abstract.
