| 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. |

| Abstract | 奥津カオリン鉱床は花崗緑岩中の熱水交代性の塊状粘土鉱床であって, 中心部に白色粘土鉱体, それをとりまいて石英沸石帯,更にその外側に緑簾石帯からなる変質の帯状分布が存在する. 放射能異常は外側変質帯の緑簾石帯に集中しており, そこにトリウムの濃集が認められる. 本鉱床の放射性元素の濃集は変質帯形成の機構と密接に関連するものとみられる. |

| Title Alternative | Phlogopites and coexisting pargasites in wehrlite from the northern Kanto mountains, central Japan |
| FullText URL | pitsr_043_001_013.pdf |

| 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. |
