Abstract

Any genetic theory explaining the origin of ore deposits of the Mississippi Valley type must be in accord with all aspects of the geologic setting that existed at the time the deposits were formed. The basinal brine theory is no exception. Unfortunately there is still great disagreement among geologists on most facets of the mechanism, such as the source of the metals, the timing of their release, the origin of the saline solutions, how the metals are carried, the causes of deposition, or why it occurs where it does. The facts and speculations about all of these are discussed, with the conclusion that a great deal of additional research is needed before the hypothesis can be totally accepted.
