ABSTRACT This interim report describes the essential mineral associations in uranium deposits, most of which were examined by us during several field seasons. The listings of identifications and occurrences of the make a comparison of the deposits and districts possible and profitable. The pattern of associations and parageneses shows the great similarity of the deposits, notwithstanding the preponderance of vanadium-bearing minerals in one category and sulfides in another. Most deposits listed are in the Shinarump (this in­ cludes such new designations as Mossback, Monitor Butte and others), and Chinle formations. In Ne~r Mexico the described deposits are in the Todilto and Morrison forma­ tions.

"Black ores 11 , that is unoxidized ones, have become very important lately. They contain ----the term pitchblende being more or less synonymous with it should be dropped----and coffinite, a still problematic black mineral of uranium. The wor~ 11 unoxidized" as used here is not synonymous 'Vri th hydrothermal as some geologists interpret it. It simply means that carbonaceous matter and iron sulfides in the ore reduced the uranium or kept it reduced during deposition. This reduction could have occurred at any stage of geologic history regardless of whether uranium was of a syngenetic origin or was contributed by solutions of magmatic origin.

INTRODUCTION AND ACKNOWLEDGMENTS Our annual report, Part III, July 1, 1951, to June 30, 1952 (RM0-566) was a compilation of mineral associations in the uranium deposits of the Colorado Plateau and adjacent regions with special reference to the Triassic formations. We have continued our field and laboratory work and, therefore, have been able to expand our compilation considerably. A number of corrections of the old renort have been made and minerals listed as ilunknownn at that time have been in nart correlated with known species. Some doubt still exists~ about some uranium sulfates, which have been designated as meta­ zippeite I and II. Some unknowns still remain. These are mostly yelloi•l in color and give X-r·ay patterns and optical properties different from recognized species. - 8 -

Suggestions by Dr. and Mrs. Clifford Frondel have been of considerable value in classifying some of the minerals. The Trace Elements Laboratory of the United States Geologi- cal Survey has also been of aid in some of the identifications. Where this laboratory's identifications of important findings were reported earlier than ours it is mentioned in these pages. We enjoyed the full cooperation of Dr. Phillip L. Merritt and many other members of the Division of Raw 1-l:aterials of the Atomic Energy Commission during this work. The personnel at Grand Junction, Colorado, especially Drs. Abraham Rosen­ zweig and c. A. F~sor and Messrs. R. A. Laverty and E. B. Gross have aided us in every possible manner. Many mine operators and foremen have pointed out interesting occurrences to us.

F~LANATIONS OF DATA The data are arranged by areas where this is possible. Plus signs are used to designate relative~y important amounts of the mineral. A minus sign indicates small to very small amounts of the species in the deposit. No sign means the amounts cannot be estimated. These estimates ~ in n£ way gu indication of the grade Q! total quantity of ~ in ~ ~ or urosuect. A auestion mark after the name indicates in­ complete information, usually on account of difficulty of verification by reliable tests on microscopic amounts. Several unknown U-minerals are listed on the basis of their unidentified X-ray patterns and optical properties. Since some of these occur in a number of localities, the X-ray pattern of only one of each has been listed in the appendix. These specimens are starred under locality and in the auuendix for easier reference. Unfiltered Fe radia­ tion was-used for X-raying. Camera radius- 57.3 mm. Asphaltite, also called thucholite by some investigators, is a carbonaceous material which is different from material that contains identifiable plant structures. It contains U as uraninite in microscopic amounts. If uraninite is submicro­ scopic or has not been identified as this mineral, the tables just state that U is "high11 in this organic material. There are, of course, numerous llcommon 11 minerals present, like quartz, goethite, hematite, different carbonates, and heavy residuals that are found in all clastic formations. These are not listed. Gypsum while nearly ah;ays present has been mentioned only in some places where it was conspicuous in its associations. - 9 -

An appendix has been added to this report ~vhich gives optical data as well as partial powder X-ray patterns for the unkno~m minerals. It is hoped that any person who has previously identified one of these species will let us share in his knov1ledge.

The numbers after the specimens are our o~ AE numbers and are given to help to locate a particular specimen where several similar ones were collected from the same locality. - 10 -

APPENDIX

The X-ray powder patterns (unfiltered Fe radiation, camera radius 57·3 mm.) and the optical properties for the unknown species which are starred in the text are given below. The lines of the po'l'ider patterns with d (1. 70 are not listed, as they are of little diagnostic value here. As many as nine specimens from an eaual number of different loce.lities ~;ill have identical patterns with only minor differences in intensities. The optical pro­ perties are far from complete but are the best obtainable considering the extremely small grain sizes of the minerals. - 41-
