13. Characteristics supporting the association with carbonatite are: multiple carbonate generations with differing compositions, breccias healed by carbonate, comb-texture of carbonate, amygdales of dolomite, the stable isotope composition of carbonate; metasomatic alteration, fenitization and carbonatization of the associated rocks; the occurrence of apatite, fluorite, phlogopite, valleriite and baddeleyite.
14. metamorphites, Mesozoic igneous intrusive rocks, Tertiary volcanic and sedimentary breccias, and Quaternary alluvia. The Precambrian Halloran Complex has been subdivided into the following formations: (1) Silver Lake Peak Formation, mostly quartzofeldspathic gneisses; (2) Cree Camp Formation, quartzites and metarhyolites; (3) Riggs Formation, metamorphosed carbonate rocks. This complex is intruded by dioritic rocks. Regional metamorphism produced parageneses of the almandine amphibolite facies. Metablastesis was a major phenomenon, partial fusion was a local one. The rocks are, therefore, metatexites. Regional metamorphism was followed by diaphthoresis, accentuated in a zone of dislocation.
