The Mistastin Lake Impact Structure As A Terrestrial Analogue Site For Lunar Science And Exploration, Marianne M. Mader
The Mistastin Lake Impact Structure As A Terrestrial Analogue Site For Lunar Science And Exploration, Marianne M. Mader
Electronic Thesis and Dissertation Repository
The impact cratering record on the Moon is important for many reasons, from understanding early solar system chronology to probing the lunar interior. In order to maximize scientific return from future lunar missions, it is useful to: 1) study terrestrial impact craters to better understand impact processes and products, and 2) develop appropriate human and robotic exploration strategies aligned with geological goals.
This research shows that the intermediate-size Mistastin Lake impact structure, in northern Labrador, Canada, is an unparalleled lunar analogue site, which includes both an anorthositic target and an almost complete suite of impact lithologies, including proximal ejecta deposits. …

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 …
