  A phase of granulite facies metamorphism associated with a major fault at about Ma is most important. Inliers of Precambrian metamorphic rocks in the Perth Basin also provide evidence of various phases of post-Archaean deformation and highgrade metamorphism (e.g., at c. lOO_O Ma, Northampton domain and Ma, Naturaliste domain, Fig. ).Cited by: 7.   Precambrian structures and metamorphic rocks of Central Australia and Tennant Creek, N.T.

In conclusion let me reiterate my main reasons for interpreting the Vijayan-Highland Series-Southwest Group as a basement-supracrustal relationship (Katz, , p. ). 1. The Highland Series-Southwest Group structures are simple linear trends in comparison with the more complex Vijayan structures. 2. There appears to be in certain places a cross-cutting relationship where Highland. The Warramunga Group at Tennant Creek, Central Australia is a Precambrian sequence of essentially slate-greywacke alternation and is metamorphosed to greenschist facies during regional tectonism. Seven chlorites carefully separated from the chloritic slates and chloritic schists have been analysed by X-ray fluorescence spectroscopy and by other. The stratigraphic distribution in Australian Precambrian rocks of columnar stromatolites, organosedimentary structures formed by blue-green algae, has been investigated. Their morphology is being studied according to methods developed in Russia. The discovery of successive different assemblages supports not only regional but also intercontinental stratigraphic correlations which are in. metamorphic rocks of Tennant Creek area, Central Australia T.

The new edition covers the same topics in a more concise and accessible format and is replete with explanatory figures, tables, and illustrations. Structural analysis of Precambrian metamorphic rocks south of Bancroft, Ontario, has disclosed fold structures in lithologic layering, which are examined on the working hypothesis that two distinct generations are present. Folds of the first system, in the southern part of the mapped area, are.
