| Abstract: | Abstract— The Devon Ice Cap, Northwest Territories, has been targeted for searches for extra-terrestrial material in the Canadian Arctic. Of three expeditions (1981, 1986, 1990), only the last met with weather conditions favourable for meteorite reconnaissance. Surveys were carried out on the ice cap margin, along boulder trains brought to the surface along ice layers, supra-glacial stream and lake sediments, and the ubiquitous cryoconite that covers the ice surface. In addition, outwash streams and plains were covered, in the hope of discerning meteoritic material lying on the Lower Palaeozoic bedrock. No meteorites were recovered, though a number of pseudotaks were identified as potential searching grounds for future expeditions. Samples of cryoconite, supra-glacial lake sediments and outwash silts were collected, and some of these have been given a preliminary examination. SEM analysis indicates that this material represents a new source for micro-meteoritic material, analogous to the deposits found in Greenland. |
