Tin-Bearing Chalcopyrite and Platinum-Bearing Bismuthinite in the Active Tiger Chimney, Yonaguni Knoll IV Seafloor Hydrothermal System, South Okinawa Trough, Japan
OKAYAMA University Earth Science Reports, Vol. 12, No. I, 1-5, (2005) Tin-bearing chalcopyrite and platinum-bearing bismuthinite in the active Tiger chimney, Yonaguni Knoll IV seafloor hydrothermal system, South Okinawa Trough, Japan Kaul GENA, Hitoshi CHmA and Katsuo KASE Department ofEarth Sciences, Faculty ofScience, Okayama University, Okayama 700-8530, Japan The active sulfide chimney ore sampled from the flank of the active TIger chimney in the Yonaguni Knoll N hydrothermal system, South Okinawa Trough, consists of anhydrite, pyrite, sphalerite, galena. chalcopyrite and bismuthinite. Electron microprobe analyses indicated that the chalcopyrite and bismuthinite contain up to 2.4 wt. % Sn and 1.7 wt. % Pt, respectively. The high Sn-bearing chalcopyrite and Pt-bearing bismuthinite are the first occurrence of such minerals on the submarine hydrothermal systems so far reported. The results confirm that the Sn enters the chalcopyrite as a solid solution towards stannite by the coupled substitution ofSn#Fe2+ for Fe3+Fe3+ while Pt enters the bismuthinite structure as a solid solution during rapid growth. The homogenization temperature of the fluid inclusions in anhydrite (220-31O°C) and measured end-member temperature of the vent fluids (325°C) indicate that the minerals are precipitated as metastable phases at temperature around 300°C. The Sn-bearing chalcopyrite and Pt-bearing bismuthinite express the original composition of the minerals deposited from a hydrothermal fluid with temperatures ofabout 300°C.

LOCALITIES, GEOLOGICAL SITUATION AND MINERAL ASSOCIATIONS Comparative analysis of telluride occurrences found in the territory of Slovakia and Transcarpathians (Ukraine) has shown that there is distinct difference between the mode of Au;Ag;Bi;Te;Se mineralization of these regions. But within the area of distribution of neovolcanites Bi;Te;Se;S mineralization is generally represented by similar mineralogical phases. In the Transcarpathian region bismuth tellurides (tsumoite, pilsenite, joseites, native bismuth and poorly studied sulpho;seleno; tellurides of bismuth) were found only in metasomatites as secondary quartzites of the Vyghorlat;Guta ridge area. (Il'kivtsy, Podulky, Smerekiv Kamin'). The similar mineralization have been also found in some neovolcanites of Slovakia (Poruba pod Vigorlatom, Remetska Hamra).

The specimen was discovered in a fragment from the cameronite [ideally, Cu5-x(Cu,Ag)3+xTe10] holotype material from the Good Hope mine, Vulcan, Colorado (U.S.A.). It occurs as black grains of subhedral to anhedral morphology, with a maximum size up to 65 µm, and shows black streaks. No cleavage is −2 observed and the Vickers hardness (VHN100) is 158 kg·mm . Reflectance percentages in air for Rmin and Rmax are 38.1, 38.9 (471.1 nm), 36.5, 37.3 (548.3 nm), 35.8, 36.5 (586.6 nm), 34.7, 35.4 (652.3 nm). Spiridonovite has formula (Cu1.24Ag0.75)S1.99Te1.01, ideally (Cu1-xAgx)2Te (x ≈ 0.4). The mineral is trigonal and belongs to the space group P-3c1, with the following unit-cell parameters: a = 4.630(2) Å, c = 22.551(9) Å, V = 418.7(4) Å 3, and Z = 6. -

The investigation focused on identifying the pigments and their combinations in the paint recipes. One hundred ninety-three micropoints randomly chosen from the white, yellow, orange, pink, brown, red, grey, black, green, and blue areas were measured for major and minor elements. The compositional types separated within each color indicate different recipes. -

The general usage of the term is to include as pseudomorphs both petrifactions and molds, and also: (1) Any mineral change in which the outlines of the original mineral are preserved, whether this surface be a euhedral crystal form or the irregular bounding surface of an embedded grain or of an aggregate. (2) Any mineral change which has been accomplished without change of volume, as evidenced by the undistorted preservation of an original texture or structure, whether this be the equal volume replacement of a single crystal or of a rock mass on a geologic scale. -
