  The Geological Survey of Japan(GSJ)has

been processing some series of rock reference

samples for major,minor and trace elements,

isotopic compositions and isotopic ages.

  The first series of two samples JG4

granodiorite and JB-1basalt was issued in

l967and1968.Processing of the second series

of GSJ rock reference samples,《《Igneous rock

series”,started in Apri11981and was com・

constituents for this second series Of samples

as we11as for the first series of samples JG-1

and JB-1have been reported(ANDo6渉αム,

1987).

  Processing of the third series of GSJ rock

reference samples,更璽Sedimentary rockseries”,started in April1986and the first

issue of three samples of this series was

completed in February1987,which are J:Lk-1

fresh water lake sediment,JLs-11imestone

and JDo4dolomite.Some other samples of

this series(slate,chert,and stream sedi-

they will be reported elsewhere.

  This is the.first compilation of major and

(communicated and published)received by

proposed by the evaluation of statistical

 About210kg of wet JLk-1sample(H20±:69.3%)was spread out in thin plastic

containers to be dried by an electric fan under

room temperature until the weight becomes

to constant.After43days,about73.5kg of

dried sample(H20±:12.3%)was obtained.

Then the sample was m皿ed in a high-

alumina lined ball mill of221iter capacity

(for about100kg of silicate materials)with

flint balls,for about10hours.Finally about70

kg of fine powdered sample(H20.±:9.9%)

was obtained.During grinding process2.4%

of water was lost.

 Cleaned rock pieces (JLs-1 and JDo-1,

about100kg each)were brok:en with a sledge

須藤定久・丸茂克美・伊藤司郎・寺島 滋

                要  旨地質調査所(GSJ)岩石標準試料“堆積岩シリーズ”の第一陣として下記の3試料を調製(1987年2

月)発行した.

JLk-1 湖底堆積物,滋賀県琵琶湖,高島町沖合3。8km,水深63m地点の湖底表層堆積物(0-20cm).

スミス・マッキンタイヤー式採泥器を使用.風乾試料。

JLs-1 石灰岩,北海道上磯郡上磯町,日本セメント株式会社義朗(がろう)鉱山,戸切地(へきれじ)

鉱床450mLにおいて採取.上磯石灰岩の地質時代は未詳であるが,コノドント等の研究により,後期

三畳紀の可能性のあることが示唆されている.

JDo-1 ドロマイト,栃木県安蘇郡葛生(くずう)町,吉澤石灰工業株式会社,三峯地区名木久保鉱床,

中部ドロマイト層(厚さ約120mのほぼ中心の層準)より採取.同地域には葛生町を中心として,二畳

系に属する石灰岩,ドロマイトが馬蹄状に広く分布している.

 これらの3試料について,主成分,微量成分および同位体組成等について国際共同分析を進めている.

1989年3月迄に,17研究機関から29件の主・微量成分定量結果の報告を受けた(定量結果総数1,134),

保証値を決めるには分析データ数がまだ不充分な段階であるので,上記の定量結果をそのまま表示し,

若干の統計的な検討を加えた.

 併せて,上記3試料についてのDTA(示差熱分析)測定結果と,JLk-1の電子顕微鏡による観察結

果を例示した.
