| dc.description.abstract | Haughton is a 23-million year old impact structure with an apparent crater diameter of 23-km, formed in mixed target rocks of the Canadian High Arctic on Devon Island [1]. At the time of impact, the target stratigraphy comprised 1880 meters of Lower Paleozoic sedimentary rocks unconformably overlying granulite-facies tonalitic and granitic gneisses of the Precambrian Canadian Shield. A location near the center of the structure, characterized by strong negative gravimetric and positive magnetic anomalies, has been coined “Anomaly Hill” [3]. Highly shocked lithic clasts resembling pumice are particularly abundant at this locale, including carbonate-rich and gneiss clasts [4, 5]. In this study, a hand specimen from Anomaly Hill was investigated using an array of advanced analytical techniques. The goal is to constrain shock conditions experienced by Haughton crystalline basement rocks and their post-shock evolution. | |
