| Title Alternative | The Geochemistry of Rocks from Asama Volcano, Japan. New Approaches in the Quantitative Interpretation of the Chemical Composition of Volcanic Rocks |

| Abstract | In dealing with the geochemistry of volcanic rocks, it appears imperative, first, to refine the procedure of rock analysis with respect to both major and minor components, and second, to improve present methods of interpreting analytical data on common rock suites such as basalts, andesites and dacites. In regard to the first problem, the rapid method of silicate analysis as described by Shapiro and Brannock (1956) and by Riley (1958) deserves special attention. With such a method it is possible to estimate the accuracy and precision of data with far greater ease than is possible with a classical one, yet without any loss of quality. For the determination of some components, however, it is felt that the procedures recommended previously lack precision and/or simplicity. In Part I of this paper, new methods are suggested for these components. The sum of Mg, Ca and Mn is titrated with EDTA in the presence of Al, Fe and other metals, using thymolphthalein complexone as indicator at pH 10-10.5. The sum of Al and Fe is determined by the back-titration of excess EDTA with the standard Cu solution. PAN is used as indicator at pH about 4, and tartrate is added as the masking agent of Ti. Na and K are determined by flame photometry using very dilute solutions (1-5ppm Na or K), without the separation of other metals and without the use of the internal standard. Sr is included in the scheme of analysis, and is determined by flame photometry according to the standard addition technique. These procedures are tested for their accuracy using the standard samples G-1 and W-1 (Tables 3, 5, 9, 12 and 15). Procedures for other components are also described in the text in full detail. The system of analytical procedures recommended is shown in Table 16. To investigate the problem of the interpretation of compositional variation, typical rocks from Asama volcano and the surrounding area were selected, namely, andesites and dacites of calc-alkaline type. Twenty-one samples, described in Tables 18 and 19, are analyzed according to the above procedures. Results are shown in Table 20. Variation diagrams are presented in Figs. 3 to 5. Since it may be questioned whether the "trend" seen in the diagrams implies a genetic relationship, a least squares approximation technique has been introduced in order to determine whether the composition of the main components of a rock (F) can be expressed by the linear combination of a selected set of compositions of a magma and the phenocrysts crystallized from it : F(o)=F(1)x(1)+F(2)x(2)+······+F(m)x(m) ······(1) where F(1), F(2), ... denote the compositions of a magma and minerals, and F(o) is the calculated composition of F. These calculations lead to the conclusion that there are at least two series of rocks in Asama (Tables 25 to 30 and Fig. 9), distinguished from each other mainly by their K(2)O content. Those rocks showing features of assimilation (Aramaki, 1963) all belong to the K(2)O-rich series. Contents of minor components such as TiO(2), MnO, P(2)O(5) and SrO are analyzed by the linear regression technique in two ways, for example : TiO(2)(o)=C(1)x(1)+C(2)x(2)+ ······(2) and TiO(2)(o)=aMgO+bFe(o) +cK(2)O ······(3) These methods are found useful in discriminating rocks of different ongm and in distinguishing the characteristic behavior of each component. Results of calculations (Tables 31 to 34) support the conclusion reached by calculations based on the contents of major components. |

| Abstract | The authors studied time-to-time variability of 100 patients with internal diseases in 100 ECG's over a period of 15 minutes. The variavirity were observed on eleven electrocardiographic items which were measured in 12 leads (I～III, (a)V(R)～(a)V(F), V(1～6)). The electrocardiograms were recorded by same technician, who carefully recorded in confomity to the description on the variability due to techinical and biologocal sources in Simonson's writing and were measured by one of the authors. Frequency distribution of differences between each two electrocardiograms of the same patients are shown in Figures (from 1 to 11) and 5% rejection limits of these differences, which were calculated in use of the stochastics, were as follows : P duration (sec. ) : + 0.022 >X(0)> - 0.021 P-Q duration (sec.) : + 0.029 >X(0)> - 0.024 QRS duration (sec.) : + 0.018 > X(0)> - 0.013 R-R interval (sec.) : + 0.168 >X(0)> - 0.141 QT Ratio (%) + 10.01 >X(0)> - 7.89 QT(c) : + 0.032 >X(0)> - 0.022 P/PR segment : + 0.914 >X(0)> - 0.832 QT/TQ + 0.192 >X(0)> - 0.190 T/R V(5) : + 0.116 >X(0)> - 0.090 AQRS (front. plane) : + 13. 29°>X(0)> - 13.83° AT (front.

| Abstract | The Kamioka mine, Gifu prefecture, working the largest lead and zinc deposit in Japan, lies in the eastern corner of the Hida gneiss complex. The skarn minerals in this mining district are genetically divided into the following three groups. Skarn A : Recrystallized skarn, formed by a regional metamorphism of impure limestone beds. The creation of skarn A is same in age to the formation of the Hida metamorphic complex. Skarn B : Zoned skarn along the contact between limestone and Inishi syenitic rock, having a same origination to Shimonomoto granite. The formation of skarn B is closely related to the intrusion of Shimonomoto granite. Skarn C : Pyrometasomatic skarn, formed by pyrometasomatic replacement of limestone probably after the deposition of the Mesozoic Tetori formation. The ore deposits of the Kamioka mine are composed of the pyrometasomatic skarn (skarn C) called "Mokuji" and the hydrothermal deposits called "Shiroji". Skarn A and skarn B have no genetical relation to the ore deposits. But skarn A acts the valuable role for the stratigrahical classification of ore deposits and limestone beds. |

| Abstract | 鳥取県大山火山の西北麓の地下水中に潜存するガス成分比は Ar : 0.34～0.40 (cc/l) 1.48～1.64 (%) O(2) : 6.69～9.08 (cc/l) 27.92～35.30 (%) N(2) : 15.16～17.23 (cc/l) 63.22～67.92 (%) の範囲内で定量できる.また,飽和度は次の如くである. O(2) : 87.8～113.9 (%) N(2) : 110.5～123.2 (%) この結果を地表水と比較して,O(2)の飽和度は小さいが,量的な差異はあまりみられず,地表水と地下水の中間的な性質を示している.地質構造,地形が溶存ガス成分比に及ぼす影響は,地下水の流通経路が長距離とみなされる場合に若干のO(2)の消費が認められ,短距離で湧出したと思われるものにはO(2)の飽和度が大きい傾向がある.また,水理地質的にみて,地質と湧出量には密接な関連を見出せるが,ガス成分には影響を与へてはいない. |

| Abstract | 東郷鉱山,方面･麻畑ウラン鉱床の基盤岩および母岩は粘土化が著しく,その特徴として次のことが挙げられる. (a)粘土鉱物の種類,存在量は,鉱床の酸化帯･非酸化帯にはゞ規制されている.(b)粘土化の程度は原岩の種類により異なり,同一種数の岩石では酸化帯における変質が特に顕著である.(c)粘土量とウラン含有量との間には明確な相関は見出せないが,モンモリロナイトの量についてのみ観察すると,おおよそ負の相関がみられる.また,粘土化の主体をなすモンモリロナイトは,結晶度が良好で熱水変質が示唆きれる.化学分析の結果,SiO(2)の量が少ないので珪ばん比が異常に小さいが,ウラン鉱床近辺においてモンモリロナイト化に伴なう珪化帯が認められず,珪酸の逸脱が考えられる.鉱量的にみて,両鉱床の主体をなすウラン鉱物が燐顧塩鉱物であり,珪酸塩鉱物が少ないことなどから,モンモリロナイト化作用と鉱化作用との間には,直接関連がないものと考察される. |

| 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 |
| FullText URL | pitsr_043_001_013.pdf |
| Author | Tazaki, Koichi| Inomata, Michiya| |
| 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 | A report on the physically handicapped persons caused by rheumatoid arthritis in Tottori Prefecture, Japan |
| FullText URL | 044_055_060.pdf |
| Author | Kitayama, Minoru| |
| Abstract | The physically handicapped persons caused by rheumatoid arthritis were studied in Tottori prefecture in July 1973. The following results were obtained ; 1. The hand i capped per sons of 265, who were recognized as the handicapped by the government authori ties, were observed. The prevalence rate was 4.7 to 10,000 of the population and 15 to 1, 000 of the total number of the hand i capped. 2. The prevalence rate of the handicapped to the total number of patients with rheumatoid arthritis was 15.4%. 3. On a reginal distribution, the prevalence rate of the handicapped to the regional population were calculated between from 0.20‰ to 0.77‰. The result showed that it was higher at rural than at urban districts. 4. The prevalence rate to population gradually increased with aging, especially over the fiftieth years. The prevalence rate of the number of serious handicapped (class 1+2) to the total number of handicapped was regnlarly at 40% between 30 and 60 years of age, but it increased over 70 years of age. 5. The sex ratio of fernIe to male was 3.3 : 1 on the total handicapped and 2.9 : 1 on the serious handicapped persons. On the other hand, the ratio was 5.1 : 1 on the group under 59 year s of age and 2.4 : 1 on the groupe over 60 years of age at the total handicapped. And then, the ratio was 5.0 : 1 on the younger group and 2.6 : 1 on the older group at the serious handicapped persons. |

| Abstract | I MEDSPECT is a medical mass spectrometer for continuous in-vivo measurement of tissue, blood and respiratory gases. Interfacing catheter for tissue in measurement has Teflon membrane. The permeability and perfusion rate for various gases through its membrane varied with temperature. The temperature coefficient of Teflon catheter in the range of 15℃-40℃ is approximately constant with -2% of correction per degree for oxygen and carbon dioxide. Linear correlation was confirmed experimentally. II The brain tissue gas tensions were measured in ten dogs with intra-venous anesthesia at normothermia and deep hypothermia using perfusion cooling, including circulatory arrest for 30 minutes at 20°C of cerebral temperature. On average, the brain tissue P(O2) was 15mmHg in normothermia when the arterial P(O2) showed 95mmHg and the brain tissue P(CO2) was 49mmHg when the arterial PC02 showed 30mmHg. The brain tissue carbon dioxide tension gradually decreased by cooling and increased during circulatory arrest for 30 minutes; from 45mmHg to 72mmHg. The brain tissue oxygen tension increased during cooling from 15mmHg to 41mmHg and decreased in the circulatory arrest; from 41mmHg to 36mmHg. III The ischemic muscle gas tension was measured in a 22-year-old man, who was suffered from thromboangiitis obliterans bilaterally, and had the popliteal autovein bypass surgery 3 months ago. Control oxygen tensions in the both anterior tibial muscles showed about the same; 35mmHg and 36mmHg respectivelly, and the P(O2) of the non-operated side showed remarkable low level of 18mmHg as compared with the side of arterial reconstruction surgery after 5-minutes ankle exercise. |
