Summary

The Archean Dolodau carbonatite dykes occur near a late tectonic syenite stock located in the Northern Volcanic Zone of the Abitibi greenstone belt. The biotite sovite and amphibole-biotite silicocarbonatite dykes produced fenitization of the host rocks. The Dolodau carbonatites compare favourably with Phanerozoic carbonatites in petrography, mineralogy and geochemistry. An Archean age is suggested by field geology and the isotope data available. The similarities suggest that Archean carbonatite petrogenetic processes were similar to modern day processes.

Zusammenfassung

Die archaischen Karbonatitgänge von Dolodau liegen in der Nähe eines spättektonischen Syenit-Stockes in der nördlichen vulkanischen Zone des Abitibi Greenstone Belts. Die Biotit-Sovit- and Amphibol-Biotit Silicokarbonatit-Gänge führten zu Fenitisierung der umgebenden Gesteine. Die Dolodau-Karbonatite lassen sich gut mit phanerozoischen Karbonatiten vergleichen, was Petrographie, Mineralogie and Geochemie betrifft. Ein archaisches Alter wird durch Geländebeziehungen and Isotopendaten belegt. Diese Ähnlichkeiten weisen darauf hin, daß archaische Karbonatit-bildende Vorgänge ihren modernen äquivalenten ähnlich sind.
