Origin of zircon in jadeitite from the Nishisonogi metamorphic rocks, Kyushu, Japan
On the basis of internal structures, laser ablation U–Pb ages and trace element compositions, the origin of zircon in jadeitite in the Nishisonogi metamorphic rocks was examined. The zircon comprisesExpand
Invisible gold in arsenian pyrite from the high-grade Hishikari gold deposit, Japan: Significance of variation and distribution of Au/As ratios in pyrite
Abstract Au and As concentrations in pyrite grains from the Hishikari deposit were extensively determined by secondary ion mass spectrometry (SIMS) and electron probe microanalysis (EPMA) toExpand
Marine shallow-water hydrothermal activity and mineralization at the Wakamiko crater in Kagoshima bay, south Kyushu, Japan
Abstract Submarine hydrothermal fluid emanation from a small sediment mound associated with bubbling gas was observed in the Wakamiko crater that is located 5 km offshore at 200 m depth in KagoshimaExpand
Clay Minerals in an Active Hydrothermal Field at Iheya-North-Knoll, Okinawa Trough
Iheya-North-Knoll is one of the small knolls covered with thick sediments in the Okinawa Trough back-arc basin. At the east slope of Iheya-North-Knoll, nine hydrothermal vents with sulfide mounds areExpand
Mg-rich clay mineral formation associated with marine shallow-water hydrothermal activity in an arc volcanic caldera setting
Abstract Shallow-water hydrothermal activity, represented by venting of hydrothermal fluid around 200 °C, occurs in the Wakamiko submarine crater at 200 m water depth in Kagoshima Bay, southwestExpand
Enhanced photoefficiency in positive-tone direct patterning of metal complexes for forming patterned indium tin oxide films
Abstract The efficiency of positive-tone directly photo-patternable 4-(2-nitrobenzyloxycarbonyl)catechol and 4-(6-nitroveratryloxycarbonyl)catechol complexes of indium tin was improved by tuning theExpand
Invisible gold and arsenic in pyrite from the high-grade Hishikari gold deposit, Japan
Abstract Gold occurs as both electrum (a natural alloy of gold and silver) and invisible gold in arsenian pyrite in the Hishikari epithermal gold deposit in Japan. Microanalyses of arsenian pyriteExpand
Origin of omphacitites from the Nishisonogi metamorphic rocks, western Kyushu, Japan: comparison with jadeitites
Two types of omphacitites are distinguished in ultramafic melanges that are intercalated with epidote–blueschist facies schists of the Nishisonogi metamorphic rocks in western Kyushu, Japan. One isExpand
Stonogobiops yasha, a new shrimp-associated goby from Japan
A new shrimp-associated goby is described from the Ryukyu Islands, Japan that is easily distinguished from other congeneric species in having reddish-orange stripes on a white body and only two median cephalic sensory pores on the head. Expand
