A summary of the theories of the origin of the Lake Superior copper ores, with evidences pertaining thereto

Author

Eva Endurance Hirdler

Abstract

"In each of the foregoing theories we obtain sound reasoning in connection with many facts. Therefore a correlation of these facts ought to give us enough material to deduct a sound theory. The most plausible supposition seems to be that all metallic ores are derived ultimately from the interior of the earth, from a great metallographic province, when they are delivered by igneous eruptives near or at the surface"--Conclusion With Reasons, page 29.
