A petrographic study is made of the granitic and
related metamorphic rocks at Harrison Hot Springs, B.C.
this thesis contains a general treatment of the regional
and structural geology of the general area. The petrography
of the various rock types is discussed under two main
headings the granitic rocks, and the metamorphic rocks.
Heat given of by the intrusive magma converted the
adjacent unmetamorphosed sediments to hornfelses of the
cordierite-anthophyllite subfacies and pyroxene-hornfels
facies. These rocks are arbitrarily subdivided into rock
types on the basis of their mineraloglcal compositions,
rather than on the field occurrence. These assemblages
are discussed with reference to the facies classification
and the mineraloglcal phase rule.
It is concluded that the hornfelses were derived by
thermal metamorphism of aluminous-chloritic argillaceous
sediments; that the cordierite-anthophyllite hornfelses were
originally rich in MgO and FeO metasomatism was not an
important process In the formation of the metamorphic
assemblages. / Arts, Faculty of / Geography, Department of / Graduate
