Data collected as part of a report on the Roundup Quadrangle in Montana including laboratory data on waters (pp. 1-46) and sediments (pp. 47-100) as well as field data (pp. 101-223).

Abstract: Field and laboratory data are presented for 1,263 water samples and 961 sediment samples from the Roundup Quadrangle, Montana. The samples were collected by Los Alamos National Laboratory; laboratory analysis and data reporting were performed by the Uranium Resource Evaluation Project at Oak Ridge, Tennessee.

Appendices containing supplementary analytical data of various stream, sediment, and rock samples, in addition to uranium occurrence reports and elemental concentration data to accompany a report on U.S. uranium resources in the Dubois Quadrangle, Idaho and Montana.

From Purpose and Scope: "The Dubois Quadrangle, Idaho and Montana (Fig. 1), was studied to identify geologic environments and delineate areas favorable for uranium deposits. These reports summarized field observations and contained preliminary evaluations of geologic environments for uranium deposition. The identification of environments favorable for uranium deposition involved collection and interpretation of radiometric, geochemical, and geologic data."

From abstract: All geologic conditions in the Dillon Quadrangle (Montana and Idaho) have been thoroughly examined, and, using National Uranium Resource Evaluation criteria, environments are favorable for uranium deposits along fractured zones of Precambrian Y metasediments, in the McGowan Creek Formation, and in some Tertiary sedimentary basins.

"Field and laboratory data are presented for 1,455 water samples and 1,502 sediment samples from the Kalispell Quadrangle, Montana. Uranium values have been reported by the Los Alamos National laboratory in Report GJBX-48(77). The samples were collected by Los Alamos National Laboratory; laboratory analysis and data reporting were performed by the Uranium Resouce Evaluation Project and Oak Ridge, Tennessee."

"Field and laboratory data are presented for 965 water samples and 1,102 sediment samples from the Glendive Quadrangle, Montana. The samples were collected by Los Alamos National Laboratory; laboratory analysis and data reporting were performed by the Uranium Resource Evaluation Project at Oak Ridge, Tennessee."

"Field and laboratory data are presented for 1005 water samples from the Wallace Quadrangle, Idaho; Montana. The samples were collected by Los Alamos National Laboratory; laboratory analysis and data reporting were performed by the Uranium Resource Evaluation Project at Oak Ridge, Tennessee."

Geophysical drilling logs produced by the Bendix Field Engineering Corporation for uranium drilling explorations in the Missoula and Bitterroot Valleys. "Most of the drill holes were geophysically logged from total depth to surface by Goodwell, Inc., logging units. The logs obtained included the following: Gamma-ray, spontaneous potential (SP), resistivity, neutron, caliper, and density. In-house BFEC units also logged several holes, obtaining potassium/uranium/thorium (KUT) logs from MB-2, MB-6, MB-8 and MB-12." from page 7 of report

Handwritten logs compiled by the Bendix Field Engineering Corporation containing lithologic descriptions of cuttings made for uranium drilling explorations in the Missoula and Bitterroot Valleys. The logs are organized by the type of sedimentary rock and depth of the sample.
