Summary

[edit]
Description
English: Original caption on flickr (excerpt): Black smoker chimney rock (8.8 cm across), partial cross-section slice of two amalgamated chimneys. Collected 19 November 1981 by the deep-sea submersible Alvin (Alvin dive # 1156). Locality: seafloor hydrothermal vent at 2597 meters depth, northern East Pacific Rise, near-easternmost Pacific Basin. Coordinates: 20° 51.00’ North, 109° 04.00’ West.
The golden-brown, metallic-lustered, sparkly material along the upper left margin is principally chalcopyrite (CuFeS2, copper iron sulfide). The dark material in the rest of the specimen is mostly a mix of chalcopyrite and sphalerite (ZnS, zinc sulfide). The whitish material is principally anhydrite (CaSO4, calcium sulfate).
Deutsch: Probe mit Massivsulfiden eines „Schwarzen Rauchers“ (Breite knapp 9 cm). Teil eines Querschnittes durch zwei miteinander verwachsene Schlote. Aufgesammelt am 19. November 1981 durch das Tiefseetauchboot Alvin (Alvin-Tauchgang Nr. 1156). Ursprungsort: Hydrothermalschlot in 2597 m Tiefe, nördlicher Ostpazifischer Rücken, Ostpazifik. Koordinaten: 20° 51.00’ Nord, 109° 04.00’ West.
Das golden-metallisch glänzende und glitzernde Material ist im Wesentlichen Chalcopyrit (Kupferkies, CuFeS2, Kupfer-Eisensulfid). Das dunkle Material ist überwiegend eine Mischung aus Chalcopyrit und Sphalerit (Zinkblende, ZnS, Zinksulfid). Das weißliche Material ist im Wesentlichen Anhydrit (CaSO4, Kalziumsulfat).
