The place of articulation in Japanese moraic-nasals is known to vary in accordance with the following sound and is assumed to be uvular in the word final position. This paper attempted to describe articulatory variability of word-final moraic-nasals using the X-ray microbeam speech production database in Japanese. The results depicted substantive inter-speaker variability in three of the four words examined. Moreover, 75% of the data examined were deemed unlikely to be uvular nasals and the lips were likely to be closed in 40% of the data. The results do not support the claim that word-final moraic-nasals are uvular.

The Teine mine is a epithermal Au-Ag-Cu deposit located at the west part of Sapporo, Hokkaido, Japan. More than 30 veins are distributed in the 5km2 area. So far, 48 mineral species are reported from the Teine mine. However, mineralogical study is not enough to describe the wide variety of mineral occurrence in this mine. The authors perform a descriptive study of ore samples stored at the Hokkaido University Museum and found 15 newly observed minerals from the Teine mine. Especially, cupropavonite,hodrushite,koritnigite, krautite and poubaite are first report from Japan. Poubaite, PbBi2Se2Te2, found in goldfieldite grain, is idiomorphic and less than 30 μm in diameter. It shows creamy white color and metallic luster. Bireflectance is strong. The observed empirical formula, PbBi2(Te2.0Se1.9S0.1) Σ4, is consistent with the ideal formula (Zdenek et al., 1987).
