Abstract
Geochemical studies of the Rolla, Mo., 1° x 2° quadrangle were begun in 1977 as part of a joint multidisciplinary study of the quadrangle by the U.S. Geological Survey and the Division of Geology and Land Survey, Missouri Department of Natural Resources. The study is to access the mineral resource potential of the area by integrated geologic, geochemical, and geophysical studies.
The geochemical work to date has been directed at the characterization of the sedimentary and igneous rocks in the quadrangle through spectrographic and chemical analyses of whole-rock samples and dilute-hydrochloric-acid insoluble-residue samples of whole rock from widely spaced drill holes. Sixty-two drill holes have been selected for study from the sample library of the Missouri Division of Geology and Land Survey. None of the holes are company-confidential, none intersect economically significant mineralized ground, and only a few are located in known ore-bearing trends.
The analytical results for drill hole no. 23, Missouri log numbers 21239 and 23878, and for drill hole no. 24, Missouri log number 12320, are given in this report. Drill hole no. 23 is located in sec. 8, T. 28 N., R. 6 E., in Wayne County, and drill hole no. 24 is located in sec. 9, T. 35 N., R. 2 W., in Crawford County.
