Abstract
A study was conducted at the Dufferin Aggregates Mosport Pit to examine the sedimentary processes occurring during the formation of Oak Ridges Moraine deposits and the processes responsible for their deformation. Detailed sedimentological analysis suggests an ice-proximal glaciofluvial setting for these deposits. Deformation structures found within silt, sand, and gravel were likely created through the loading of overriding flood deposits, melting of buried ice-blocks, and remobilization of saturated sediments. These ice-proximal glaciofluvial deposits likely represent a small portion of the topset deposits from a glacier-fed fan-delta. The possibility that these sediments are part of a much larger ice-walled esker deposit has not been ruled out. Incorporating the study of deformation structures with standard sedimentological techniques allowed for a better understanding of the processes that occurred during and after sediment deposition and the ice-proximal nature of the depositional environment.
