The Geology of the New Quebec Crater: Discussion
Two different theories of the origin of the New Quebec Crater are presently receiving serious consideration. One is the meteorite impact theory and the other is the volcano-tectonic theory, proposed by K. L. Currie (1965). Currie's thorough investigation of this crater and his theory on its origin have received much less attention than they deserve; partly because of the much too modest 50/50 claim which he makes for the probability of his theory versus the impact theory. The purpose of this discussion is to add one more piece to the impressive evidence which Currie has presented to support his theory. In particular, a quite plausible environment is suggested which satisfies the necessary conditions for the growth of large well-developed
