Late Professor o f Mineralogy in the Sheffield Scientific School o f Yale University, LSSS-1906 SECOND EDITION FIRST THOUSAND N E W Y O R K Jo h n w i l e y & s o n s Londbn: CHAPMAN & HALL, Limited 1907 IRIS - LILLIAD - Université Lille 1 Copyright, 1907 BY GRACE C. PENFIELD IRIS - LILLIAD - Université Lille 1 PREFACE TO FIRST EDITION. The minerals are arranged in the tables as follows: I. According to the six systems of crystallization and their prominent subdivisions, the minerals of each subdivision being arranged in accordance with the chemical classification as adopted b y D ana. II. According to the elements, emphasis being given to min­ erals which are important from an .economic standpoint. III. With reference to geological occurrence and association. Minerals are given three ranks in the tables, indicated by the type used in printing the names of the species, as follows:— (i) Minerals of the first rank are either very common, or espe­ cially important from a scientific or geological standpoint, and their names are printed in heavy type, capital letters. (2) Min­ erals which are of rather rare occurrence, including some very rare species provided they are especially important from an economic or scientific standpoint, are given a second rank, and their names are printed in heavy type, capital and small letters. (3) The names of rarer and less important species, constituting a third rank, are printed in small type. All of the important minerals (450 species) are included in the tables, and generally very rare species have been omitted, except where chemical com­ position or some pronounced features have given them special significance. The weighting of the minerals, or assignment to first, second or third rank, is an arbitrary matter, based upon the writer’s experience, but it is believed that students will appreciate this feature of the tables, enabling them almost at a glance to form some estimate of the relative importance of the several species.

T he “ Tables of Minerals” was written by Prof. Penfield in 1903 for use in connection with lectures on Descriptive Miner­ alogy in this School and has been used by successive classes since then. The present edition has been carefully revised, chiefly in the matter of bringing the statistics of mineral production down to date. Acknowledgment is gratefully made of the assist­ ance of Dr. George F. Kunz, who kindly furnished the figures for the values of the gem stones. Part III of the Tables has been rewritten and enlarged, with the purpose of making that section more useful to students who have only a slight knowledge of geology or petrology. W. E. Ford.

N o te .— The chief object of tables of this kind is that they may serve as a guide and reference-list to accompany lectures on crystallography and descriptive mineralogy. In a measure, also, the tables may be made the basis of determinative mineralogy, for if it is discovered that a mineral crystallizes in a certain system, the list of minerals in that system may be studied and the name of the species found by. comparison either with labeled specimens or with descriptions as given in the texts referred to. ISOMETRIC SYSTEM; NORMAL GROUP. N o te .— The pyritohedral and tetrahedral groups are tabulated separately, while a few minerals belonging to the rarer plagihedral division are included in the normal group. Elements. \ T. B. * Sys.

Allin A thesis submitted in partial fulfillment of the requirements for the degree of Masters in Geoscience: Geology Option Montana Technological University 2019 ii Abstract Experiments were conducted to determine the relative rates of reduction of aqueous sulfate and aqueous arsenite (As(OH)3,aq) using foils of copper, nickel, or cobalt as the reductant, at temperatures of 150ºC to 300ºC. At the highest temperature of 300°C, very limited sulfate reduction was observed with cobalt foil, but sulfate was reduced to sulfide by copper foil (precipitation of Cu2S (chalcocite)) and partly reduced by nickel foil (precipitation of NiS2 (vaesite) + NiSO4·xH2O). In the 300ºC arsenite reduction experiments, Cu3As (domeykite), Ni5As2, or CoAs (langisite) formed. In experiments where both sulfate and arsenite were present, some produced minerals were sulfarsenides, which contained both sulfide and arsenide, i.e. cobaltite (CoAsS). These experiments also produced large (~10 µm along longest axis) euhedral crystals of metal-sulfide that were either imbedded or grown upon a matrix of fine-grained metal-arsenides, or, in the case of cobalt, metal-sulfarsenide. Some experimental results did not show clear mineral formation, but instead demonstrated metal-arsenic alloying at the foil edges.

  • Structure and Composition OXIDATION ZONE
    OXIDATION ZONE Structure and Composition The first scanty information on the oxidation zone of the Rubtsovskoe deposit was obtained as a result of drilling in the early 1970s. Three major subzones were distinguished downward: (1) a leached oxidized ore zone largely composed of iron hydroxides and kaolinite; (2) a secondary oxide enrichment subzone with cuprite, native copper, malachite, azurite, cerus - site; and (3) a secondary sulfide enrichment subzone (that transitions to an underlying zone of mixed ores) with chalcocite and covellite (Stroitelev et al. , 1996). As a result of our observation in underground workings, the structure, min - eralogy, and genetic features of the oxidation zone of the deposit were spec - ified substantially. The top of the orebody is supergene altered to the highest degree at the WSW flank, where it is located higher in altitude. The upper boundary of the orebody gently plunges ENE and the oxidation zone (we do not discuss the mixed ores) gradually pinches out; the oxidation zone extends along the strike of the orebody for approximately 300 m. In the WSW part of the ore - body, the oxidized ores occur in the altitude interval from +137–138 to +163 m. The lower boundary of the oxidized ores rise toward the ESE and the main part of the oxidation zone occurs in the range of +144–145 to +153–157 m. The oxidized part of the orebody varies from 2 to 8 m in thickness, reaching 15–17 m in swells and occasionally more than 20 m. Both underlying and overlapping rocks are dominated by clayey minerals; these are wall-rock argillaceous alterations, frequently altered as a result of ore oxidation especially adjacent to the contact of the orebody.

Ihe report was illustrated with lantern slides of photographs taken on the trip, and exhibits of specimens. Mr. George Vaux, Jr. described a trip to Franklin, N.

Centy., 1900, 60 ; from Bul. Bozcmccnie, 8, 351 --365).-In the original paper, the physical and chemical properties of 12 kinds of Roumanian MINERALOGICAL CHEMISTRY View Article Online283 petroleum are described and tabulated. The flash points of the various fractions are given, and their suitability for use as burning oils is also discussed. These petroleums contain very variable amounts of volatile oils, and ethylisobutane and isopropane were found in the fractions boiling below 70”. E. w. w. Melonite from South Australia. By ALFREDJ. HIGGIN(Trans. Roy. Xoc. South Austdia, 1899, 23, 21 1-212).-This mineral, pre- viously only known from California, has now been found with quartz and calcite at Worturpa, South Australia. The thin lamells have a brilliant metallic lustre; the cleavage planes are silver-white to reddish- brown. H- 1.5 ; sp. gr., 7.6.

Titaniferous Magnetites. By JAMESF. KENP(School of Mines Quart., 1899, 20, 323-356 ; 21, 56-65).-Titaniferous magnetites, with the exception of the occnrrences in sands, are almost invariably found associated with rocks of the gabbro type, and have originated by a process of segregation from the magma, The mineral, as a rule, contains vanadium, cbromium, nickel and cobalt, which together may amount to several per cent.
