    A new ophiolite occurrence in NW Sudan – constraints on Late Proterozoic tectonism (1990)

    Notes: Mafic–ultramafic sequences in the Jebel Rahib fold-and-thrust belt of NW Sudan comprise the metamorphosed equivalents of obducted oceanic lithosphere. Primary features like pillow-structures, quenchtextures, igneous layering and primary minerals like chromian spinels and pyroxenes are partly preserved. Geochemical investigations confirm the field evidence and reveal the occurrence of harzburgites, ophiolitic chromites, gabbros, gabbroic cumulates and basalts of primitive tholeiitic compositions resembling transitional MORBs. The age of low-grade overprint of the basaltic rocks can be limited to 860–740 Myr (K–Ar). The existence of an ophiolite, as well as its close interfingering with highly deformed basin sediments, provides unambiguous evidence for a cycle of extensional and compressional tectonics in NW Sudan during Pan-African times. Consequently, the concept of an older, stable Proterozoic, or even Archaean, ‘African Craton’onto which the juvenile Pan-African Nubian Shield assemblages were accreted, needs revision.

    Relationship Between Thermal Denaturation of Porcine Muscle Proteins and Water-holding Capacity (2002)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: : Differential scanning calorimetry was used to investigate denaturation characteristics of pork muscle proteins from carriers and noncarriers of the RN-gene. Pork from RN-carriers deviated from noncarriers in maximum denaturation temperatures and denaturation enthalpy, with proteins of RN-carriers being the most heat-labile. Correlation studies on the results showed that water-holding capacity was significantly correlated to changes in enthalpy of the population mainly representing myosin tails and sarcoplasmic proteins (p 〈 0.001). Finally, the influence of ultimate pH and preheating on thermal characteristics of porcine muscle proteins was studied. Myosin tails and sarcoplasmic proteins were most sensitive to pH changes, while myosin heads were most sensitive to preheating simulating stress-induced temperature increases.

    Upper Proterozoic and Phanerozoic Pole Positions and Potassiumargon (K-Ar) Ages From the East Sahara Craton (1989)
    Oxford, UK : Blackwell Publishing Ltd
    Geophysical journal international 97 (1989), S. 0

    Notes: Seven new palaeopole positions from southern Egypt and northern Sudan with ages ranging from Upper Proterozoic (720 Ma) to Uppermost Cretaceous are presented and discussed in the context of the apparent polar wander path (APWP) of Africa. Rockmagnetic studies were also performed to determine the carriers of magnetization and to test the reliability of the remanence data. Ages pertinent to the APWP were taken from the literature or-for most of the localities-have been determined by K-Ar dating on whole rocks or minerals. the localities, geographic coordinates, ages, rock types and positions of the palaeomagnetic South Poles are as follows:(1) Gebel Gifata, SW Egypt, 29.0°E, 25.5°N, Upper Cretaceous (65–70 Ma) limestones and shales, 45.0°E, 81.5°S. (2) Northern Volcanic Field, N Sudan, 33.3°E, 19.0°N, Upper Cretaceous (80 Ma) basalts, 97.8°E, 55.9°S. (3) Nusab el Balgum complex, SW Egypt, 29.3°E, 23.3°N, Triassic (216 Ma) rhyolites and subvolcanics, 50.7°E, 64.1°S. (4) Sabaloka complex, N Sudan, 32.6°E, 16.3°N, Lower Devonian (395 Ma) volcanics, subvolcanics, metamorphosed quartzite, 55.8°E, 43.5°S. (5) Bir Safsaf, SW Egypt, 29.3°E, 23.1°N, Cambrian (586 Ma) dykes, 249.7°E, 80.0°N. (6) Nabati, N Sudan, 33.7°E, 18.1°N, Pre-Cambrian-Lower Cambrian (589 Ma) diorite and granite, 314.1°E, 67.9°N. (7) Kadaweb, Red Sea Hills, N Sudan, 36.3°E, 20.1°N, Proterozoic (720 Ma) gabbros, 319.6°E, 1.0°N.Nine other localities of Mesozotc and Palaeozoic rocks gave no reliable pole positions, mostly due to secondary magnetizations. the seven palaeopoles cover the Phanerozoic and Upper Proterozoic and increase the palaeomagnetic database for Africa. For the Phanerozoic there is coincidence with the palaeomagnetic data of other African cratonic areas indicating that Africa has behaved as a more or less stable block since the end of the Pan-African orogeny.

    Notes: In trimmed muscle types of four game species the dry matter, crude protein, crude fat, ash, Ca, P, Mg, Na, K, Cu, Zn, Fe, and Mn contents were determined. Samples of the m. semimembranosus and m. longissimus dorsi of each of 10 red deer, fallow deer, roe-deer and wild boars from the Southwestern region of Hungary in the end-winter period were analyzed, and mean values, related to dry matter, were compared. The game muscle samples had much lower crude fat, more Ca, P and microelements, especially Cu and Fe, when compared with published data for the respective muscles of domestic animals.
