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

Jackson Blue is a first magnitude spring in the karst terrane of northeast Florida. Previous studies have identified inorganic fertilizer as the source of high nitrate levels in the spring. Agricultural land use and karst vulnerability make Jackson Blue a good model for conservation concerns. This work offers an aggregation of studies relating to the springshed, providing a valuable tool for planning and conservation efforts in the region. An analysis of nitrate levels and other water quality parameters within the springshed did not reveal significantly different values between agricultural and forested land use areas. Confounding factors include: high transmissivity in the aquifer, interspersed land use parcels, and fertilizer application in forested areas due to commercial pine stand activity.
