Abstract

Seven glauconite samples from the Magmont area yield a 359 + or - 22 m.y. Rb-Sr isochron. The Rb/Sr ratios for these seven samples are significantly lower than the ratios for glauconite samples from distant, unmineralized sites. The glauconites from Magmont are postulated to have been affected by the same thermochemical event(s) that produced the SE Missouri ore deposits, and therefore to date that mineralization.-G.J.N.
