Iodine and Algae in Sedimentary Rocks Associated with Iodine-rich Brines
Neutron activation analyses of iodine and uranium in Paleozoic sedimentary rocks from the northern Oklahoma platform of the Anadarko basin show 0.9 to 12.3 ppm I and 0.07 to 8.7 ppm U. The samples were taken from strata in Kingfisher County, Oklahoma, where anomalously high concentrations of iodine were found in associated subsurface brines. Micropaleontological examinations reveal algal strands in the more iodine-rich rocks.
