A Sedimentological Study Of Modern And Ancient Lacustrine Environments At Michael Bay, Lake Huron, Lindsay D. Nakashima

Theses and Dissertations (Comprehensive)

Modern and ancient environments associated with Lakes Algoma and Huron were studied according to attributes of stratigraphy, sediment texture, parameters, sediment size distribution, bedforms, and primary sedimentary structures. Results from a computation of wave refraction diagrams and from an examination of the wave climate characteristics indicate that the modern embayment is low energy.

A sediment texture comparison between modern and ancient environments indicates that higher energy pervailed in the ancient environment relative to the present day environment. The cobble and gravel sediments as well as an extensive belt of foredunes preserved in the ancient environment are evidence of this high …

Sedimentology Of The Glaciofluvial Deposits Of Woolwich And Pilkington Townships, Ellis Bowes

Theses and Dissertations (Comprehensive)

The Lake Wisconsin glaciofluvial deposits in Woolwich and Pilkington townships are examined for the purpose of environmental reconstruction and the establishment of the paleocurrent patterns. Sediment grain size and primary sedimentary structure are used to define sedimentary facies of environmental studies while the distribution of indicator pebbles, trends in clast size reduction and primary sedimentary structures and employed for paleocurrent analysis. The exposures most representative of the depositional sequences encountered are examined and provide an impression of the sedimentological characteristics of the various glaciofluvial deposits.

Three distinctive types of glaciofluvial deposits can be identified on the basis of surface morphology …

A Comparative Study Of Nickel Sulphide Deposits Within The Area Of The Canadian Shield, Robert G. Kreiner

Theses and Dissertations (Comprehensive)

In order to plan the future development of the Canadian Shield within a conceptual framework as suggested by the Mid-Canada Corridor concept, both the presently developed and potential, natural resources of this area need to be evaluated for knowledgeable development and management. To this purpose, various areas of nickel sulphide deposits within the area of the Canadian Shield have been studied with the object of determining similar sequences of intrusive events and their spatial relationships.

Within the Sudbury area, Ontario, five periods of intrusive activity have been recognized, each period characterized by an initial intrusion of acidic composition, followed in …
