Abstract
The New Quebec Crater is a circular depression in the acid Archaean gneisses of northeren Quebec, about 2 miles in diameter and 1300 ft deep. The crater is roughly bowl shaped, with a prominent rim elevated 300 to 500 ft above the surrounding barrens. The rim structure is a relatively recent deformation resulting in a systematic outward dip of rock sheeting, and radial distribution of other curviplanar strctural elements. Rocks of the rim are strongly mineralized with epidote and hematite, and are altered to sericite. These minerals are not found in the same rock units outside the rim. Glaciation of the rim appears to have removed little or no material. No evidence of impact was found.
