PHASE CHANGES in Cu 2 S AS a FUNCTION of TEMPERATURE 1. PREVIOUS WORK
National Bureau of Standards Special Publication 364, Solid State Chemistry, Proceedings of 5th Materials Research Symposium, issued July 1972. PHASE CHANGES IN cu2s AS A FUNCTION OF TEMPERATURE William R. Cook, Jr. Gould Inc., Gould Laboratories Cleveland, Ohio 44108 and Case Western Reserve University Cleveland, Ohio 44106 The high-'copper phase boundary of Cu2s deviates from stoichiometry above 300 °C, first becoming copper deficient, then above - 1075 °C becoming copper rich. The maximum copper content occurs at the monotectic temperature of 1104 °C. The strong effect of oxygen on the hexagonal-cubic transition in Cu2S was confirmed; the transition was also found to be sensi tive to the type of pretreatment of the material. The high temperature tetragonal "Cu1 96s" phase is stable between Cu1.95S and Cu2s, at temperatures of - 90° to - 140 °C. The tr~nsi tion to the tetragonal phase is extremely sluggish. The true composition of djurleite has been shown to be approximately Cu1.93S. The phases near the chalcocite-digenite region of the diagram may be grouped into those with hexagonal close packing of sulfur atoms and those with cubic close packing of sulfurs. This is important in understanding rates of transformation among the various phases that occur in this area of the diagram. Key words: Chalcocite; cu2s; digenite; djurleite; nonstoichiometry; phase relations. 1. PREVIOUS WORK Fairly thorough explorations of the Cu-s phase diagram between cu2s and cu1• ,shave been made by a number of previous workers [1-8] 1 The resulting diagram may be seen in figure 1 taken largely from Roseboom [7] and Riu [8]. -

SAMDLING FOR cnRALT AT RORNITE, ALASKA By Jeffrey Y. Foley 1 INTRODIICTION Carrollite (CuCo2S4), an ore mineral of cobalt, is known to occur in the Ruby Creek Cu-Zn deposit at Bornite (fig. 1), in northwest Alaska (5, q). 2 The events leading to mineralization of dolomite and argillite units and the distribution of these rocks in the Bornite district are among the topics covered in a PhD discertation by M. W. Hitzman of Stan- ford University (in progress). Hitzman has identified carkollite and cobaltiferous pyrite at numerous intersections in diamond drill core belonging to Rear Creek Mining Corporation, the present operator of the property. A brief visit to collect bulk samples was made by a Bureau geologist in July, 19R1, as part of the Alaska Critical Metals program. ECONOMIC GEOLOGY Hitzman summarizes the distribution of cobalt as occurring: 1) "...as late cobaltiferous pyrite rims on earlier formed pyrite grains in pyritiferous, ferroan dolo- mite with disseminated sphalerite and massive siderite" 2) "...as carrollite in high-grade hornite, chalcocite, chalcopyrite, and sphalerite ore at higher levels in the deposit." 1 Geologist, U.S. Rureau of Mines, Alaska Field Operations Center, Fairbanks. 2 Underlined numbers in parentheses refer to items in the list of references at the end oF this report. ; - > . ; - .>;. -1,; g n/ /- ; > @ ! - xi #."R-: 3 2 vl- t 7:'i "^. -

They are Rhynia gwynne- vaughanii Kidston & Lang, Aglaophyton major D. S. Edwards, Horneophyton lignieri Barghoorn & Darrah, Asteroxylon mackiei Kidston & Lang, Nothia aphylla Lyon ex Høeg, Trichopherophyton teuchansii Lyon & Edwards and Ventarura lyonii Powell, Edwards & Trewin. The superb preserva- tion of the silica permineralisations produced in the hot spring environment provides remarkable insights into the anatomy of early land plants which are not available from compression fossils and other modes of permineralisation. -
DESCRIPTIVE MODEL of KIPUSHI Cu-Pb-Zn
Model 32c DESCRIPTIVE MODEL OF KIPUSHI Cu-Pb-Zn By Dennis P. Cox and Lawrence R. Bernstein DESCRIPTION Massive base-metal sulfides and As-sulfosalts in dolomite breccias characterized by minor Co, Ge, Ga, U, and V. GEOLOGICAL ENVIRONMENT Rock Types Dolomite, shale. No rocks of unequivocal igneous origin are related to ore formation. [The pseudoaplite at Tsumeb is herein assumed to be a metasedimentary rock following H. D. LeRoex (1955, unpublished report).] Textures Fine-grained massive and carbonaceous, laminated, stromatolitic dolomites. Age Range Unknown; host rocks are Proterozoic in Africa, Devonian in Alaska, Pennsylvanian in Utah. Depositional Environment High fluid flow along tabular or pipe-like fault- or karst (?)-breccia zones. Tectonic Setting(s) Continental platform or shelf terrane with continental or passive margin rifting. Ore formation at Tsumeb and Ruby Creek predates folding. Associated Deposit Types Sedimentary copper, U-veins, barite veins. Sedimentary exhalative Pb-Zn may be a lateral facies. DEPOSIT DESCRIPTION Mineralogy Ruby Creek: pyrite, bornite, chalcocite, chalcopyrite, carrollite, sphalerite, tennantite. Tsumeb: galena, sphalerite, bornite, tennantite, enargite. Kipushi: sphalerite, bornite, chalcopyrite, carrollite, chalcocite, tennantite, pyrite. Less abundant minerals in these deposits are linnaeite, Co-pyrite, germanite, renierite, gallite, tungstenite, molybdenite, and native Bi. Bituminous matter in vugs. At Apex mine, marcasite. Texture/Structure Massive replacement, breccia filling, or stockwork. Replacement textures of pyrite after marcasite at Ruby Creek and Apex. Alteration Dolomitization, sideritization, and silicification may be related to mineralization. Early pyrite or arsenopyrite as breccia filling or dissemination. Ore Controls Abundant diagenetic pyrite or other source of S acts as precipitant of base metals in zones of high porosity and fluid flow. -

ABSTRACT Minerals containing cobalt as an essential element display systematic trends in their diversity and distribution. We employ data for 66 approved Co mineral species (as tabulated by the official mineral list of the International Mineralogical Association, http://rruff.info/ima, as of 1 March 2016), represent- ing 3554 mineral species-locality pairs (www.mindat.org and other sources, as of 1 March 2016). We find that cobalt-containing mineral species, for which 20% are known at only one locality and more than half are known from five or fewer localities, conform to a Large Number of Rare Events (LNRE) distribution. Our model predicts that at least 81 Co minerals exist in Earth’s crust today, indicating that at least 15 species have yet to be discovered—a minimum estimate because it assumes that new minerals will be found only using the same methods as in the past. Numerous additional cobalt miner- als likely await discovery using micro-analytical methods. -

The sedimentary iron is well manifested in the Paleozoic terranes, and assigns great relation with the Hercynean geodynamic regime, which marks the Gondwanean environment during this time. The results of these processes manifest as the establishment of exploitable iron Formations depos- it situated in the Tafilalt Ordovician basin of the eastern Anti Atlas of Morocco. Key words: Hercynean, Gondwanean, exploitable iron deposits, Tafilalt Ifs, Ordovician, Anti Atlas, Morocco _____________________________________________________________________________________ INTRODUCTION Iron Formations (IFs) originates from sedimentary deposition processing, and they are characterized by a high grade iron tenor which manifest as tiny or laminated chemical facies and contains more than 15% sedimentary iron. The ore is formed by iron oxides and hydroxides such as hematite (Fe2O3) and magnetite (Fe3O4) both consti- tute the major part of the mineralized rock. -
