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