Characteristics Of Impactites In The Central Uplift Of The Mistastin Lake Impact Structure, Canada, Alaura Singleton
Characteristics Of Impactites In The Central Uplift Of The Mistastin Lake Impact Structure, Canada, Alaura Singleton
Electronic Thesis and Dissertation Repository
This thesis investigated the nature of parautochthonous and allochthonous impactites found in the erosional remnant of the central uplift of the Mistastin Lake impact structure, central Labrador. This was carried out with the goal of discovering details about the composition and formation conditions of these complex materials. This study involved fieldwork and a range of laboratory techniques. As part of this work, a geological map of Horseshoe Island has been created, and is the most detailed to date. The shock metamorphic features found in the uplifted target rocks have been assessed, and indicate a peak shock level of 5a (35-45 …

Impact cratering is a ubiquitous geological process that has shaped planetary bodies of the Solar System and beyond. While the impact cratering record on Earth has been poorly preserved, the Martian surface is characterized by a very old and cratered terrain. Central uplifts within complex impact craters are of particular interest as they expose deep-seated material, some of which may correspond to samples of the early Martian crust. Central uplift formation is, however, still a poorly understood geological process. This research investigated the origin of the exposed bedrock in the central uplifts of two Martian complex craters as well as …
