| Abstract | ウラン鉱床の成因およびウラン鉱物の生成状況を解明するためには,ウラン含有量と同時に,ジルコニウム,イットリウム,ストロンチウムなどの含有量の多少を知ることが,人形峠周辺の鉱床の研究過程において重要となった.これら諸元素の定量をかなりの精度で微量の場合にまで迅速に行なうため,溶液法による蛍光X線分析法を検討した.試料は細粉としたのち,王水などの強酸で分解し,残りはロ過除去してのち,濃縮して一定容となし,その一部をあらたに試作した液体試料保持台(内容積1.8ml,液層の厚さ2.5mm)に入れて測定を行なう.タングステン管球を用い,45KV,22mAの条件で,理学電機製の装置(結晶はLiF)を用い,固定計数法によって各螢光X線(ULα,ZrKα,SrKα,YKα)の強度を計測する.各元素の標準溶液について,最適の角度,バックダウランド値,強度と濃度の関係を検討し,比較的低濃度(20μg/ml前後)まで,検量線の直線性によって,精度よく定量し得ること を知った.さらにこれら諸元素の混合溶液についても検討し,ZrKα に対するウランおよびストロンチウムの影響,さらに共存元素として含有量の多い鉄の影響をしらべ,蛍光X線法により定量した鉄の存在量による諸元素の測定値に対する補正を検討した.以上の諸検討にもとずいて,本法の迅速性を活用し,実際の各種試料について諸元素の定量を行ない,興味ある結果を得られることを知った. |

| Title Alternative | Phlogopites and coexisting pargasites in wehrlite from the northern Kanto mountains, central Japan |

| Abstract | Coexisting interstitial phlogopites and pargasites in iron rich wehrlite from the northern Kanto mountains were studied. The textural relationｓ between those interstitial hydrous minerals and major constituent minerals, such as olivines and clinopyroxenes suggest the crystallization of the former from the intergranular residual liquids. The modal amounts of phlogopites in wehrlite are less than 1%, and that of pargasites range from 2 to 5%. Microprobe analyses have been carried for those hydrous minerals and the major constituent minerals. namely, olivine, clinopyroxene and idiomorphic zoned chromite. Olivines in wehrlite from the northern Kanto mountains have rather iron-rich nature and range from Foso to Fo(80) and those coexisting with the hydrous minerals are Fo(82.5) in average. Clinopyroxenes from mica bearing wehrlite contain about 2.5% Al(2)O(3). 17% MgO and 5.5% FeO. Tentative cation per cent of Ca, Mg and Fe are calculated as Ca(42.6) Mg(48.1) Fe(9.3) in average. The present probe analyses show high magnesian nature of the interstitial phlogopites. In addition, these phlogopites are conspicuous by their high TiO(2) content ranging from 4.6 to 5.2%. Mg/Mg + Fe versus Ti relation plotted in Fig. 4 revealed that the present phlogopite are similar to that of the alkaline pyroxenite nodules from the Lashaine volcano, northern Tanzania. Pargasites in mica bearing wehrlite are also rich in TiO(2) (3.0～4.7%), whereas pargasitic common hornblende from hornblendite or gabbro are rather low in TiO(2) (0.9～1.7%). Mg/Mg+Fe+Mn versus Ti relations of amphiboles illustrate that Ti contents increase with decrease of Mg/Mg+Fe +Mn. Two different increasing trend for Ti conten t are also noticed. Idiomorphic chromites show distinct compositional variation from core to rim. Total FeO increases about 16% at rim, whereas TiO(2), Al(2)O(3) and MgO decrease at the rim. Possible crystallization scheme of those hydrous minersls is proposed in Fig. 10, where the maximum stability limits of phlogopite and hornblende are shown with the curve for begining of melting of basalt. Separation of liquid fraction from cumulate phase with a small trapped intergranular liquid might occur at point A. The liquid fraction then might move upward through the course II. In cumulate phase, intergranular liquid might crystallize pargasitic amphibole by the reaction with olivine and clinopyroxene through the course I in Fig. 10. Intergranular liquid might decrease with production of amphiboles and K(2)O might concentrate in residual liquid. At final stage of crystallization, residual liquid rich in K(2)O might crystallize as phlogopite by the reactions with olivine. Decrease of Ti02 content at the nm of idiomorphic chromite might be related to the formations of Ti-rich hydrous minerals. |

| Title Alternative | Hydrogen and oxygen isotopic ratios of thermal and mineral springs in Arima area |
| FullText URL | pitsr_043_015_028.pdf |
| Author | Matsubaya, Osamu| Sakai, Hitoshi| Tsurumaki, Michiji| |
| Abstract | Saline waters of thermal and mineral springs in Arima area, at Takarazuka, and in Ishibotoke area of Kawachinagano City indicate wide ranges of δD and δ(18)O values (Table 1). Excellent linearity exists between the δD and δ(18)O values (Fig. 1) and between the δ(18)O value and the chloride concentration (Fig. 2). These facts as well as the chemical evidence of the previous investigators strongly support the view that Arima springs are admixtures of a single deep brine and local ground water (TSURUMAKI, 1964). The deep brine may have the δ(18)O value of +8.0～+8.5‰, the δD value of -25～-30‰, and the chloride concentration of 1.20～1.25 eq/l, which were estimated from the water of the maximum salinity so far reported. Because the thermal and mineral springs in Arima area closely associate with the upper Cretaceous granitic rocks, and the estimated δ(18)O value of the deep brine is similar to a value of water in isotopic equilibrium with those granitic rocks at 500～600℃, the deep brine of Arima might have been the magmatic water of those granitic rocks. The mineral springs at Takarazuka and in Ishibotoke area also show the similar linearity among Cl(-), δ(18)O and δD to those in Arima area. Therefore it is assumed that the mineral springs at Takarazuka may be of the same origin as that in Arima area, and the mineral springs in Ishibotoke area might have been the fluid associated with Ryoke metamorphic rocks. Alternatively, the deep brine in Arima area may be isotopically and chemically similar to the saline formation waters in Illinois basin (GRAF et al., 1966). The high δD values and salinities of those formation waters were attributed to the isotopic and chemical fractionation during the passage of water through sediments. The deep brine in Arima area may be genetically similar to those saline formation waters. If such a saline water could have formed in Osaka basin, it is not surprising to find out the similar brines at Arima and Ishibotoke which are the northwestern and southeastern rims of the basin, respectively. At the present, it cannot be answered which of these two models is more probable. Further studies on other saline springs fluid inclusions of Cretaceous granitic rocks may be useful in order to solve this problem. |

| Title Alternative | An isotope study of hot springs in Nagano Prefecture |
| FullText URL | pitsr_050_017_024.pdf |
| Author | Matsubaya, Osamu| Sakai, Hitoshi| Kusakabe, Minoru| Sasaki, Akira| |
| Abstract | Water samples from 28 hotsprings and mineral springs in Nagano Prefecture, central Japan, were examined for their stable isotope ratios of hydrogen, oxygen, carbon, and sulfur. Spring waters of Kashio are highly saline and enriched in heavy isotopes of oxygen and hydrogen (δ(18)O=-2.5～-4.6‰, δD=-54～-57‰). Linear relationships among δD, δ(18)O, and Cl(-) suggest that spring waters are the mixtures of a deep brine and local surface water. Extrapolation of the linear relationships indicates that the deep brine is both isotopically and chemically very similar to the deep brine previously suggested for the springs of Arima, Takarazuka, and Ishibotoke of which δD, δ(18)O, and Cl(-) are estimated as -33‰, +8.0‰, and 44g/l, respectively. A common origin may be warranted among these postulated brines, while their provenance is yet to be worked out. The hot springs in Matsushiro are a Na-Ca-Cl type of high carbonate content. Their hydrogen and oxygen isotope ratios (δD=-71～-46‰, δ(18)O=-9.1～-2.0‰) are higher than the local surface water. On the basis of the relationships among δD, δ(18)O, and Cl(-), they are considered to be the mixtures of fossil sea water and certain water of meteoric origin of which Cl(-) is about 4g/l and δ(18)O is higher by about 3‰ than the local surface water. The latter may be meteoric water circulating in the marine sedimentary formations (Green Tuff formations) with soluble sea salts. Isotopic exchange with carbonate minerals in the formations explains its (18)O enrichment. Spring waters from Yashio and Isobe (Gunma Pref.) as well as Yunosawa and Yatate (Akita Pref.) were previously interpreted to be mixtures of fossil sea water and local surface water of low Cl(-) content. Re-examination of their data revealed that the meteoric waters responsible for these springs contain about 3g/l Cl(-), similar to the value obtained for Matsushiro. However, unlike Matsushiro, the meteoric waters in these areas are found to be isotopically similar to the local surface waters. Waters from other hot springs studied here are of simply meteoric origin, thus belonging to the GreenTuff type water previously defined. |

| Title Alternative | Relict igneous minerals of the Sangun metamorphic rocks of the Tsuboi district, Okayama Prefecture |
| FullText URL | pitsr_054_043_053.pdf |

| Abstract | The Sangun metamorphic rocks of the Maniwa Group are well developed in the Tsuboi district, Okayama Prefecture. These metamorphic rocks consist mainly of psammitic and pelitic sedimentary rocks and lavas and pyroclastics of basic to acidic compositions that recrystallized during the Sangun low-grade regional metamorphism. The metamorphic rocks in this district underwent to a considerable extent a mineralogical and textural transformation, but still preserve in parts their original, mineralogical and textural features. Unaltered, relict clinopyroxenes and hornblendes are commonly observed in the metamorphic rocks derived from basic lavas and intermediate pyroclastics. Microprobe analyses of these relict minerals suggest that their host rocks were probably derivatives of magma(s) with a non-alkaline affinity. |
