Description:
Manned submersible studies have delineated a large and actively growing Kuroko-type volcanogenic massive sulfide deposit 400 kilometers south of Tokyo in Myojin Knoll submarine caldera. The sulfide body is located on the caldera floor at a depth of 1210 to 1360 meters, has an area of 400 by 400 by 30 meters, and is notably rich in gold and silver. The discovery of a large Kuroko-type polymetallic sulfide deposit in this arc-front caldera raises the possibility that the numerous unexplored submarine silicic calderas elsewhere might have similar deposits.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Iizasa -- Fiske -- Ishizuka -- Yuasa -- Hashimoto -- Ishibashi -- Naka -- Horii -- Fujiwara -- Imai -- Koyama -- New York, N.Y. -- Science. 1999 Feb 12;283(5404):975-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Geological Survey of Japan 1-3, Higashi-1, Tsukuba, Ibaraki 305-8567, Japan.
