Processed seismic data of Cruise ME53 1980

In the period from February 13th to March 2nd 1980 4,037 km of magnetic, gravity and bathymetric lines and 1,195 km of digital reflection seismic lines were recovered on the 2nd leg of METEOR cruise no. 53. Heat flow measurements have been performed on 13 stations; on two stations sonobuoy refraction measurements and dredging have been carried out. From a preliminary interpretation of the seismic monitor records the Mazagan Plateau is part of the Moroccan Meseta. Seawards of this stable swell lies the 75 km wide, downfaulted rift graben characterized by salt diapirs. A submarine body, 150 square kilometres large, lying at the foot of the Mazagan Escarpment in water depths of 3000 m - 3800 m beneath sea level, from which western flank few granitic fragments were retrieved, is interpreted as a subsided and tilted block of the Mazagan Plateau. The north-trending magnetic anomalies, discovered during METEOR cruise no. 46 within the Essaouira continental margin segment have also been recognized within the Tafelney Plateau segment, situated between latitudes 30°45'N and 31°30'N off Morocco. Two neo-volcanic zones were found west of the Conception Bank and west of the Betancuria Massif/Fuerteventura Is. The Mesozoic and Tertiary depositional sequences are highly deformed by small piercement structures interpreted as dykes within these zones.

Explanation: siehe dazu die angegebene Durchführungsbestimmung

Statement: During the period from the 13th February to the 2nd March 1980 BGR acquired seismic lines off Central Morocco. Lines ME53-02, ME53-04, ME53-08, ME53-17, ME53-24 and ME53-27 are processed (stacked) data. Lines ME53-03, ME53-05, ME53-06, ME53-07, ME53-09, ME53-10, ME53-23, ME53-24 and ME53-25 are processed (migrated) data.
