From abstract: Deposits of oxidized zinc ore are widely distributed in the western part of Colorado in the Rocky Mountains west of the Front Range and in the uplifted plateaus that border the main area of the Colorado Plateau. The principal production and reserves are restricted to several mining districts--Leadville. Aspen, Monarch, Spring Creek. Horseshoe, Tomichi, Tincup, and Rico--in all of which limestone and dolomites of Paleozoic age are the main host rocks. One deposit, that of the Sedalia mine near Salida has produced commercial quantities of oxidized zinc-copper ore from noncarbonate host rocks, but other known deposits in noncarbonate rocks are mostly low grade.

Abstract: This report is a synthesis of published and unpublished data on the rocks of the Anadarko basin.

From Introduction: "Detailed reports on various phases of the oil-shale mining research program have been published by the Bureau of Mines as Reports of Investigations, and numerous articles prepared by the mine staff have been published in the technical press. Summarizes of some of these publications are included in this report with other information not previously published."

From Abstract: "For about 1500 spectral lines of diatomic molecules observed by coherent radiation techniques, measured frequencies, assigned quantum numbers, and newly computed intensities are given."
