Coulsonite Fev2o4—A Rare Vanadium Spinel Group Mineral in Metamorphosed Massive Sulfide Ores of the Kola Region, Russia
minerals Article Coulsonite FeV2O4—A Rare Vanadium Spinel Group Mineral in Metamorphosed Massive Sulfide Ores of the Kola Region, Russia Alena A. Kompanchenko Geological Institute of the Federal Research Centre “Kola Science Centre of the Russian Academy of Sciences”, 14 Fersman Street, 184209 Apatity, Russia; [email protected]; Tel.: +7-921-048-8782 Received: 24 August 2020; Accepted: 21 September 2020; Published: 24 September 2020 Abstract: This work presents new data on a rare vanadium spinel group mineral, i.e., coulsonite FeV2O4 established in massive sulfide ores of the Bragino occurrence in the Kola region, Russia. Coulsonite in massive sulfide ores of the Bragino occurrence is one of the most common vanadium minerals. Three varieties of coulsonite were established based on its chemical composition, some physical properties, and mineral association: coulsonite-I, coulsonite-II, and coulsonite-III. Coulsonite-I forms octahedral crystal clusters of up to 500 µm, and has a uniformly high content of 2 Cr2O3 (20–30 wt.%), ZnO (up to 4.5 wt.%), and MnO (2.8 wt.%), high microhardness (743 kg/mm ) and coefficient of reflection. Coulsonite-II was found in relics of quartz–albite veins in association with other vanadium minerals. Its features are a thin tabular shape and enrichment in TiO2 of up to 18 wt.%. Coulsonite-III is the most common variety in massive sulfide ores of the Bragino occurrence. Coulsonite-III forms octahedral crystals of up to 150 µm, crystal clusters, and intergrowths with V-bearing ilmenite, W-V-bearing rutile, Sc-V-bearing senaite, etc. Chemical composition of coulsonite-III is characterized by wide variation of the major compounds—Fe, V, Cr. -

Rossman Division of Geological and Planetary Sciences California Institute of Technology Pasadena, California 91125-2500, U.S.A. grr@ gps.caltech.edu INTRODUCTION Optical spectroscopy is concerned with the measurement of the absorption, reflection and emission of light in the near-ultraviolet (-250 nm) through the mid-infrared ( -3000 nm) portions of the spectrum. The human interface to the geological and mineralogical world is primarily visual. Optical spectroscopy is, in particular, well suited to investigating the origin of color in minerals. The reflection spectroscopy of minerals has been motivated to a large extent by interest in remote sensing. Emission spectra are usually studied in reference to luminescence phenomena. Studies of mineral color, metal ion site occupancy, oxidation states and concentrations have generally been done with absorption spectroscopy. This chapter concentrates on single crystal absorption spectroscopy. Absorption of light by crystals can occur for a number of reasons. For many minerals, the presence of ions of transition elements (e.g., Ti, V, Cr, Mn, Fe, Co, Ni, Cu) in their various oxidation states is the cause of light absorption. In some minerals, the individual ions cause the light absorption while in others it is the interaction between ions such as between Fe2+ and Fe3+ that causes color. In some minerals, rare-earth elements are an important source of color. 2 Some minerals are colored by small molecular units involving metal ions (UOl+, Cr04 -) or anions (S 3- in sodalites). Many sulfide minerals such as cinnabar (HgS) and realgar (As4S4) owe their color to band gaps in the semiconducting sulfides. -

Cavansite, a Calcium and Vanadium Silicate of Formula Ca(VO)(Si4o1o
.. ,., Cavansite, a calcium and vanadium silicate of formula Ca(VO)(Si4O1o).4H.P, occurs as sky-blue to greenish-blue radiating prismatic rosettes up to~mm in size associated with its dimorph, pentagonite, in a roadcut near Lake Owyhee State Park in Malheur County, Oregon. Discovery of these two minerals is attributed to Mr. and Mrs. Leslie Perrigo of Fruitland, Idaho, (at this locality in 1961), and to Dr. John Cowles at the Goble locality in 1963 (see below). Associated with the cavansite and pentagonite are abundant colorless analcime, stilbite, chabazite, thomsonite and heulandite, as well as colorless to pale yellow calcite, and rare green or colorless apophyllite. This occurence and a similar emplacement (of cavansite only) near Goble, Columbia County, Oregon (co-type localities), represent the only known deposits of these two minerals in the United States. As determined by X-ray fluorescense and crystal stfiucture analysis, cavansite is orthorhombic, conforms to space group Pcmn (D2h 6), has a unit cell with a=lO.298(4), b=l3.999(7), c=9.6O1(2) Angstroms, contains four formula units, is optically biaxial positive and strongly pleochroic. Pentagonite, the dimorph, occurs as prismatic crystals twinned to form fivelings with a star shaped cross section. Also orthorhombic, it belongs to space group 12 Ccm21(C2v ), and has a unit cell with a=lO.298(4), b=13.999(7), and c=B.891(2) Angstroms, and also contains ··four formula units. The pentagonite crystals are optically very similar to cavansite, but are biaxially negative. The cell dimensions given tend to vary· to a small degree, presumably because of varying zeolitic water content. -

It was prepared as part of the Bureau of Land Management's Cultural Resource Manage- ment Program and is the second complete history of a BLM district in Colorado. A major objective of the Bureau of Land Management, Department of the Interior, is the identification, evaluation and protection of the nation's historic heritage and values, particularly those under the management of the Bureau. The history of Southwestern Colorado is designed to provide a baseline narrative for Cultural Resource Management. Paul M. O'Rourke has written a new history of the southwest corner of Colorado and in doing so, has provided a timely and original view of Colorado's heritage and history. This study will become part of the over-all history of Colorado as prepared by the Bureau and as other volumes dealing with Colorado history are written, they too will be made available to the general public. -
