    Notes: [Auszug] This coherence is shown in Fig. 1. The dashed lines on the diagram indicate the limits of scatter of Ahrens s original data, and most subsequent analyses fall within these limits, which are taken to indicate the limits of normal potassium/rubidium ratios. In view of the close coherence of ...

    On the occurrence of eclogite in Western Norway (1970)
    Springer
    Contributions to mineralogy and petrology 26 (1970), S. 12-19 
    Details
    ISSN: 1432-0967
    Source: Springer Online Journal Archives 1860-2000
    Topics: Geosciences
    Notes: Abstract Recent experimental data show that eclogites may form in the crust under conditions where total pressure exceeds water pressure. The regional distribution of eclogites in Western Norway and their association with crustal rocks makes their formation in the crust the most attractive hypothesis. Before a mantle origin should be assigned to any rock within this eclogite and garnet peridotite area it should be demonstrated that their country rocks are in a metamorphic state incompatible with the load pressures required for eclogite stability. Criteria for ascertaining eclogite formation in the crust are discussed.

    Parageneses of garnet in granulite-facies rocks, Lofoten-Vesteraalen, Norway (1969)
    Springer
    Contributions to mineralogy and petrology 23 (1969), S. 89-116 
    Details
    ISSN: 1432-0967
    Source: Springer Online Journal Archives 1860-2000
    Topics: Geosciences
    Notes: Abstract Garnet occurs widely as a secondary mineral in the granulite-facies rocks of the Lofoten-Vesteraalen islands of North Norway. The garnet-forming reactions may be inferred from the resulting textures and are interpreted as being retrograde reactions. Microprobe analyses show that garnets with high proportions of CaO and MgO occur in coronas around olivine grains in anorthosites, whereas the most iron-rich garnets formed by reaction between plagioclase and the very iron-rich pyroxenes of some monzonitic (mangeritic) rocks. Garnets ranging in composition between these extremes formed by reactions involving biotite, plagioclase and magnetite. Textural features indicate that these reactions have been induced by oxidation of the biotite; the liberated water has converted the pyroxenes to amphibole. The net effect of the reactions is to transform the granulite-facies assemblages to amphibolite-facies assemblages. The secondary garnet is nearly ubiquitous in the granulites of the outer Lofoten islands, which may show no other signs of retrogression. On Langöy in Vesteraalen garnet occurs only within a zone of strongly retrograded gneisses. Differences in bulk composition do not satisfactorily explain the distribution of secondary garnet. This distribution, and the observed oxidation textures, imply widespread penetration of the Lofoten granulites by a transient oxidizing fluid. On Langöy these fluids apparently affected only the narrow retrograded zone. The model suggests that the 1700 to 1800 m.y. Rb/Sr date obtained by Heier and Compston (1969) for the Lofoten granulites represents the time of oxidation, whereas the 2800 m.y. date for the Langöy granulites represents the original granulite-facies metamorphism.
