Abstract

The expected concentration of chlorine in the biotite fraction was not found. The chlorine was not significantly water leachable from the whole rock samples following normal grinding. The Idaho Batholith as a source for mineralizing chlorine was not established.

The chlorine distribution supports, but does not prove, a metamorphic origin for the Idaho Batholith. Cretaceous and possibly tertiary thermal events may have homogenized the chlorine in the batholith. Since chlorine seems to be so widely available in source rocks, a better way to correlate its presence to mineralization would be to study the residual chlorine from the ore deposition process.
