dc.description.abstract	dyke rocks occurring in the coldwell alkaline instrusive complex, n. w. ontario, were studied by various petrographic and geochemical means. the resulting observations indicate that 5 types of mafic alkaline lamprophyres, distinguished on the basis of chemistry and mineralogy according to the scheme of rock (1977), and 1 type of felsic tinguaite occur in the complex (in approximate order of abundance): a) ocellar camptonites b) analcite tinguaites c) quartz-bearing camptonites e) amphibole camptonites f) monchiquites lamprophyres are characterized mineralogically by phenocrysts of clinopyroxene and brown amphibole, and remnant phenocrysts of olivine...(see document for full abstract)
