<p>This study was planned as a combination of detailed field
mapping, thin section petrography, whole rock geochemistry and
amphibole chemistry of the rocks of the Port Coldwell intrusion.
It was hoped that the results of the detailed field
mapping would give a clearer picture of the stratigraphy and
structure of the intrusion. It was hoped to define the mineralogy
and textures of the various phases of the Port Coldwell intrusion
enabling a postulation of possible physical conditions under which
crystallization occurred.
Through whole rock chemical analysis it was hoped to
correlate the petrochemistry with the stratigraphy, and so to
provide a chemical explanation of the differentiation process.
Furthermore, it was hoped to classify the gabbros and through
differentiation trends provided by the plots of the analyses, to
determine whether the gabbro could be a feasible parent of the
other phases of the intrusionThe amphibole found in each phase of the intrusion was to
be determined in order to discover elemental trends and to provide
corroborating evidence of a differentiation sequence suggested
by other sources. </P> / Thesis / Master of Science (MSc)
