The purposes of the present study may be stated as follows : i. To present a logical chronological account of the physiographic development of Melville Peninsula. ii. To trace the major events of the Pleistocene glaciation and deglaciation in Melville peninsula. iii. To discuss the geomorphic processes which are active today in modifying the present surface configuration ofMelville Peninsula. iv. On the basis of the above discussion, to divide the peninsula into physiographic regions and to describe them systematically.

<p> The northwestern Melville Peninsula in the area of 69°34'N/84°50'W consists of Precambrian Shield rocks that have suffered multiple metamorphic events, including a high grade metamorphic event in the late Archean, ranging from upper amphibolite to granulite grade locally. The oldest unit present is a tonalite-granodiorite-granite suite showing both foliation and lineation and a somewhat migmatic texture. This biotite-hornblende orthogneiss has produced a Rb-Sr whole rock age date of 2.55 +/- 0.2 Ga. Field relationships indicate that this is a metamorphically induced age rather than an emplacement age. A coarse grained granitic pegmatite associated with the orthogneiss has produced a Rb-Sr isochron indicating an age of 1.83 +/- 0.06 Ga. Petrographic and field evidence indicate that this represents the emplacement age of the pegmatite. </p> / Thesis / Bachelor of Science (BSc)
