During METEOR-Westafrica cruise 46, leg 1, geophysical measurements were carried out off Morocco between 31°30'N and 32°30'N in the time period from the 8th October to the 5th November 1977. Altogether 1,855 km of 24-fold reflection seismic data were collected on lines ME46-02 to ME46-11 and on lines ME46-14 to ME46-19. For the purpose of planning the programme, the reflection seismic data were processed (12-fold stack) aboard. 3,465 km of magnetic, gravimetric and bathymetric data were collected on lines ME46-01 to ME46-26 using the new BGR digital recording system. Along lines ME46-101 and ME46-102 with a total length of 209 km refraction seismic measurements were carried out with 6 moored telemetric buoys. A total of 164 shots with charges of 5 kg up to 200 kg were fired along the two lines in distances of about 1.5 km. A distinct fault zone was discovered in the area of investigation which is associated with a positive magnetic anomaly. The fault zone strikes NNE-SSW and probably marks the ocean-continent boundary. Beside diapiric structures (salt) allochthonous structures - thrust structures - are widespread features east of the discovered fault zone and below the lower continental slope. The seismic data indicate that the evolution of the old continental margin of the East Atlantic was also controlled by large scale gravity tectonics.
From 1st May to 25th May 2011 the French Institute from Brest Institut Français de Recherche pour l'Exploitation de la Mer (IFREMER) together with BGR conducted a scientific cruise on the IFREMER research vessel L'ATALANTE, which constitutes the 1st leg of the MIRROR survey. In order to acquire supplementary marine geophysical research data to the MIRROR scientific survey a 2nd leg was performed from 2nd June to 11th June 2011. Both legs are spread over the shelf edge and slope of Morocco, the adjacent Essaouira Rise, and the easternmost abyssal plain, and are located between 33°30' N and 30°30' N. The region of MIRROR Leg 2 is situated south of Leg 1. The main research objectives were to image the deep structure of the crust, to test the origin of the magnetic anomaly S1, and to test rifting models in order to understand the nature of the continental margin of Morocco as well as the opening history of the Atlantic Ocean. Another objective was to realize a comprehensive sediment basin analysis for specifying the hydrocarbon potential of the region. In total multi-channel seismic lines with a length of 1,391 km and additional 271 km with the other geophysical methods (magnetic field measurements as well as bathymetry) were acquired. The seismic data acquired during Leg 2 were processed onboard and two of the lines were interpreted. Line BGR11-208 traverses from DSDP Site 415 to Site 416 and ties the MCS grids of both MIRROR legs as well as other former MSC surveys of BGR. Therefore, the line enables a reliable regional seismostratigraphic interpretation and a moderately well mapping of the Jurassic, Cretaceous, and Cenozoic sequences. Large compressional structures are present in the sedimentary cover along the seismic line pointing to transform faults or an activated fracture zone. Regarding the NWW-SEE trending line BGR11-202 the area of investigation can be subdivided into three structural units, a zone of rifted continental margin, a zone of initial seafloor spreading, and a zone of regular seafloor spreading as well as post-Cretaceous igneous activity. Huge rotated basement blocks are located under the shelf and uppermost slope and striking salt domes at the lowermost slope. The zone of initial seafloor spreading is characterized by a sub-basement reflector with overlying tilted basement blocks. The sub-basement reflector trends generally horizontal and appears to be a detachment fault. The magnetic slope anomaly S1 is located at foot of the slope near the western boundary of the zone of rifted continental margin.
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.
In the period from September 25th to October 19th 1979 5,260 km of magnetic, gravity and bathymetric lines and 3,567 km of reflection seismic lines were recovered on the first leg of the VALDIVIA Westafrica-cruise 1979 with the research objective to study similarities and differences in the geological development of physiographically different Northwest African continental margin segments. Test measurements have been carried out during this cruise with an “implosive" seismic sound source. The software for acquisition, calculation and presentation of gravity, magnetic and bathymetric data has been developed so that onboard presentation of free-air anomalies, Bouguer anomalies, anomalies of the earth's magnetic field and of the bathymetry could be achieved. Differences within the regional geological development of the Northwest African continental margin has been confirmed. Parts of the Moroccan continental margin are modified by a Cretaceous epirogenic uplift associated with block—faulting and halokinesis. Tertiary folding of the Western High Atlas extends into the shelf of the Tafelney Plateau segment.
Das Projekt "Staub im globalen System - prozessorientierte Forschung auf Einzelpartikelebene" wird vom Umweltbundesamt gefördert und von Technische Universität Darmstadt, Institut für Angewandte Geowissenschaften, Fachgebiet Umweltmineralogie durchgeführt. Das Ziel des Heisenberg-Programms ist es, herausragenden Wissenschaftlerinnen und Wissenschaftlern, die alle Voraussetzungen für die Berufung auf eine Langzeit-Professur erfüllen, zu ermöglichen, sich auf eine wissenschaftliche Leitungsfunktion vorzubereiten und in dieser Zeit weiterführende Forschungsthemen zu bearbeiten. In der Verfolgung dieses Ziels müssen nicht immer projektförmige Vorgehensweisen gewählt und realisiert werden. Aus diesem Grunde wird bei der Antragstellung und auch später bei der Abfassung von Abschlussberichten - anders als bei anderen Förderinstrumenten - keine 'Zusammenfassung' von Projektbeschreibungen und Projektergebnissen verlangt. Somit werden solche Informationen auch in GEPRIS nicht zur Verfügung gestellt.
The study analyses the country background, emissions trends, ongoing activities and barriers relating to the implementation of the Nationally Determined Contribution (NDC) of Morocco under the UNFCCC. A special emphasis is laid on further mitigation potentials in the fields of urban environment, the mineral sector and the transport sector. A chapter is dedicated to the relevance and perspectives of coal use.
