  Relative REE abundances of porewater in Pacific pelagic sediment: estimation by equilibrium calculations based on REE composition of Mn-oxide and apatite components
  vol.23, p. 1-12. PDF（1.36MB）
  DOI: 10.18999/bulnum.023.01

  In order to reveal REE mobilization in sediment during early diagenesis, we estimate the REE composition of porewater in Pacific sediments deposited in the Equatorial area. The Pacific sediment was divided chemically into leachate 1 (extracted by alkaline Na₂S₂O₄), leachate 2 (extracted by 0.17 M HCl) and residue. The leachate 1, leachate 2 and residue consist mainly of Mn oxide, carbonate fluorapatite (CFA), and detrital materials, respectively. The Mn oxide and CFA component are considered to provide information about REE composition of porewater. Assuming that Mn oxide and CFA in the sediment were in chemical equilibrium with the porewater in terms of REE, the REE composition (REE/ Gd ratio) of the porewater in the sediment was estimated from the REE abundance of the leachate 1 and 2. The estimated REE pattern (REE/Gd ratio) of the porewater shows La depletion and Ce enrichment relative to the deep-seawater. The difference of REE composition between deep-seawater and porewater suggests that REE in pelagic sediment is mobilized during early diagenesis.

  A petrographical note on granophyre cobble from the Carboniferous conglomerate in the Ulaanbaatar Terrane, central Mongolia
  vol.23, p. 13-20. PDF（20.8MB）
  DOI: 10.18999/bulnum.023.02

  A granophyre cobble was found from conglomerate of the early Carboniferous Altan Ovoo Formation in the Ulaanbaatar Terrane, central Mongolia. The conglomerate occurs in sandstoneshale alternations, is partly matrix-supported and partly clast-supported, and consists largely of rounded pebbles and cobbles of rhyolite with lesser amounts of quartz porphyry, sandstone, mudstone, granite, andesite and granophyre. Clast imbrication, although not common, shows their derivation from the west.
  The granophyre clast is characterized by having micrographic texture, titanite and secondary pumpellyite. One quartz porphyry clast contains pumpellyite and rock fragments of granophyre very similar to the granophyre clast, suggesting that the granophyre and quartz porphyry are likely to be related in their provenance.

  Jomon Pottery and Clay Bracelet in Dainichidaira Site in Fukushima Prefecture
  vol.23, p. 21-26. PDF（2.26MB）
  DOI: 10.18999/bulnum.023.03

  Reports of Dr. Bunnei Tsunoda Collection have been already published had three purposes. First, giving an introduction to unpublished materials. Second, contemporary revaluating materials previously published by Dr. Bunnei Tsunoda. Third, re-excavation of buried valiant materials. This report measures up to third purpose. From Dainichi Daira site in Fukushima prefecture, two valiant materials were re-excavated. One is pottery in Medium Jomon period restored to original shape. Another is clay object commonly called "Clay bracelet". This kind of material is frequent found from sites in Late Jomon Period.

  Catalogue of NARASAKA Gen'ichiro's Collection, with explanatory notes Part 2: Handwritings and picture postcards
  vol.23, p. 27-64. PDF（1.56MB）
  DOI: 10.18999/bulnum.023.04

  As the 2nd part of the catalogue of Narasaka's collection, given were the lists of handwritings by himself, letters mailed to him, and used and unused picture postcards. Among these materials, brief notes were given on the "A diary of Ise-Shima Travel" by Narasaka himself, some letters from his former students accompanied as medical doctors in the Nissin (between Japan and China) and the Nichiro (between Japan and Russia) Wars, some postcards from his colleagues studying in Germany, and some letters from one of his disciples, Dr. Med. SHIINO Kotaro.

  A Catalogue of Takaki's bryophyte collection at the Nagoya University Museum: genera with initial B (1)
  vol.23, p. 65-175. PDF（3.26MB）
  DOI: 10.18999/bulnum.023.05

  A collection database for the bryophyte specimens of Dr. Norio Takaki's (1915-2006) held in the Nagoya University Museum (NUM) is now in course of preparation. The second part of the database, about half of the records for the specimens collected in Japan with the generic name beginning with B, are given here in print in advance of the computerized database. 1990 species are included here with records of the name, locality (in Japanese), locality and habitat (in English), date of collection, collectors, and notes on label.
