      • 소백산육괴 남서부지역(남원일대)에 분포하는 편마암류의 미량원소함량과 지화학적 연구

        조규성,기상 全北大學校 基礎科學硏究所 1991 基礎科學 Vol.14 No.2

        고도의 변성작용을 받은(Amphibolite facies, 김형식, 1970) 소백산육괴 남서부지역인 전북 남원일대에 분포하는 편마암류의 근원암을 밝히기 위해 277개의 시료를 채취 Cu, Cr, Pb, Ni, Mn, Li 등의 원소를 정량 분석했다. 각 원소의 평균함량, 함량범위, 돗수분포 등을 살피고 이질퇴적암(셰일)과 변성퇴적암(편암), 편마암 및 화강암이 갖는 미량원소의 지화학적 특징을 파악했다. 본 연구지역의 흑운모편마암, 반상변정편마암, 화강암질편마암, 혼성페그마타이트질편마암의 미량원소 함량은 이질퇴적암인 셰일(Mason, 1982; 남기상, 조규성, 1988)과 이질변성퇴적암인 편암(남기상, 조규성 1987)과 매우 유사하다. 그러나 화강암류(Taylor, 1964 ; Jin M.S., 1988 ; 남기상, 조규성, 1987)의 함량보다는 2-60배 높은 값을 가지며 특히 세일과 화강암 사이에 많은 함량의 차이를 보이는 Cu, Cr, Ni 등의 원소에서 높은 함량을 갖는다. 우백질화강편마암은 셰일이나 변성최적암보다는 6개원소 모두 낮은 함량을 갖으며 화강암류와 유사한 값을 갖는다. 퇴적기원의 암석의 돗수분포는 넓고 불규칙하게 분산되지만 화성기원의 암석은 최대 빈도를 중심으로 좁게 분포한다. 따라서 흑운모편마암, 반상변정편마암, 화강암질편마암, 혼성페그마타이트질편마암은 퇴적기원의 암층이 변성의 정도에 따라 암상의 차이를 보여주는 준편마암이며 우백질화강편마암은 그 후 이를 관입한 정편마암이다. To determine the original rock types of gneisses distributed in and aroud Namwon, Chonbuk Province, which is located in the south-west of the Sobaegsan Massif, 277 gneiss samples were collected, and elements of Cu, Cr, Pb, Ni, Mn and Li were analyzed quantitatively. Average abundance, range of abundance and frequency of each element were examined, and then the geochemical characteristcs of pelitic sediment(shale), gneisses and granites were studied. The trace element abundances of biotits gneiss, porphyroblastic gneiss, granitic gneiss and migmatitic pegmatitie gneiss are very similar to those of shales (Mason, 1982;Nam and Cho, 1988) and schists (Nam and Cho,1987), while those of the gneisses show 2-60 times as high as those of granites (Taylor, 1964; Jin, 1988; Nam and Cho, 1987). Cu, Cr, and Ni abundances, in which there are big difference between shales and granites, are very high in biotite gneiss, porphyroblastic gneiss, granitic gneiss and migmatitic pegmatite gneiss. Leucocratic granitic gneiss have lower abundances in all six trace elements than those of shales and metamorphosed sediments, and have similar trace element abundances to those of granites. The fraquencies distribution of the trace elements in the case of rocks of sedimentary origin are wide and scattered irregularly, while those of rocks of igneous origin show narrow distribution, centered on maximum frequency. Biotite gneisses, protphyroblastic gneisses, granitic gneisses and migmatitic pegmatite gneisses are, therefore, considered to be para-gneisses, which show different rock faces with the degree of metamorphism; leucocratic granitic gneisses are ortho-gneiss intruded the para-gneisses.

      • 花崗岩類의 風化에 있어서 主要成分의 相對的 移動 : 特히 長水郡 山西面 花崗岩

        南基庠 全北大學校 師範大學 1978 사대논문집 Vol.4 No.-

        To investigate the weathering phenomena of Sanseo granite, the writer had got the measure value of chemical analysis of the rock. Therefore the writer have made following conclusions by serveral figures and table based on the measure value. ① Migration of various oxidized substance, increasing and decreasing, was observed more clearly in the late than the beginning stage of weathering. ② The formation of a hydroxide is proved clearly by increasing phenomena of H_2O in middle stage of weathering. ③ A scope of element migration is prescribed as a limited ones by distinct increasing phenomena of Al_2O_3 and Fe_2O_3, and decreasing of FeO, K_2O and Na_2O. ④ Though various element don t always show the same mobility, neither have a rule, the order of mobility is following : Na, K, Ca>Si>Mg>Fe^+++& & , +Al.

      • 龍華山 一帶에 分布하는 花崗巖質巖石의 微量成分 (2보)

        기상 全北大學校 敎育大學院 1986 敎育論叢 Vol.6 No.-

        Eight elements predominate in the earth's crust ; these are oxygen, silicon, aluminium, iron, magnesium, calcium, sodium and potassium and they constituted about 98 percent by weight of the crust. Conventionally it is these elements which are the major elements of igneous rocks, the remainder being the minor or trace elements. In the relationship of seven trace elements of Mt. Yonghwasan around, the author had got the measure value of microanalysis. Therefore the has reahed the following conclusions by several figures and tables based on the measure value. 1. Corelation is not suitability but chrominum and nickel are suitability. 2. The sole frequency distribution diagram is a frequency distribution of cobalt. 3. Most trace elements are not distributed uniformly throughout a rock but tend to concentrate in accessory minerals which may be particularly susceptible to redistribution by crystal settling, flow differentiation, partialfusion, or alteration.

      • 茂朱一帶에 分布하는 片麻岩의 微量成分에 대하여

        南基庠,曺圭聖 全北大學校 敎育大學院 1988 敎育論叢 Vol.8 No.-

        Petrochemical features of gneiss in Muju area, based on the geochemical consideration of trace elements and comparative investigation abundance from other rocks are as follows. Gneiss in Muju area is similar abundance of trace component with schist of Yongpori formation, shale of Gilwangri formation, gneisses and metamorphic sedimentary in Namwon and Jeonju area of sedimentary origin, and frequency distribution is irregularly widely dispersion. However it show difference from granite of igneous origin. Upon this ; origin rock of metamorphic rock can examine by analysis of trace components, and so I think that gneiss in Muju area is origin of sediments.

      • 天安 一帶에 分布하는 片麻岩類에 대한 地化學的 硏究

        The purpose of this study is to clarify the origin of gneiss which is distributed in the Cheonan area. The following is the result of geochemical study about granitic gneiss, porphyroblastic gneiss and banded biotite gneiss distributed in this area through the analysis of major and trace elements. In the gneisses, the abundance of Na_2O is less than 3.27 wt% and the ratio of TiO_2/Al_2O_3 is similar to that of clay sediments. The plot of Harker variation diagram of these gneisses belong to paragneiss area. Comparing gneisses with granite or shale, the average abundance of trace elements in gneiss is similar to that of shale. Also, the abundance range and frequency distribution of trace elements in the gneisses are wider and more dispersion than that in the granite. As shown above, granitic gneiss, porphyroblastic gneiss and banded biotite gneiss which are distributed in the Cheonan area, show a typical characteristic of a rock from sedimentary origin.

        Goldschmidts rules that minor elements in magmatic crystallization are a useful guide to the distribution of the elements during magmatic crystallization, but they are not universally vaild and have been critized on that account. The major source of this lack of universal validity seems to lie in the fact that the bonding in most minerals in not exclusively ionic, whereas the rules are predicated on a purely ionic basis. This has been carefully considered by Ringwood (1955), who shows that the electronegativity of an elements, a measure of its tendency to form covalent bonds, has an important influence on the extent to which it will proxy for another element of similar size. Inpractice this rule is found to apply to substitutions involving elements differing in electronegativity by more than 0.1. The significance of bond type on the distribution of the elements has been extensively reviewed by Ahrens (1964). The auther relationship of minor elements of Mt. Yonghwasan around, the auther had got the measure value of microanalysis. Therefore the auther have made following conclusions by several figures and table based on the measure value. 1) correlation is not suitability but chromium and nickel is suitability. 2) These 5 minor elements is precarious position ionic camouflage, ionic captured, ionic admitted, but chromium is not, in this area.

      • 全州一帶에 分布하는 花崗岩과 變成岩의 微量元素에 관한 연구

        南基庠,曺圭聖 全北大學校 1987 論文集 Vol.29 No.-

        Based on the geochemical consideration and comparative investigation, the feature of the trace elements of granite and metamorphic rock distributed at Jeonju area was studied. More mean content and wider content range of trace elements in Jeonju Gneiss than in granite was found. On the frequency distribution diagram, the frequency shows a parabolic shape with respect to the mean valre of content in case of granite, however Jeonju Gneiss shows irregularity. This fact implies that Jeonju Gneiss is rather originated from sedimentary rock. Also Jeonju Gneiss is similar to the precambrian granitic gneiss and metamorphic sedimentary of Jeonju Group with respect to the mean content and to the content range of the trace elements. It was found that the rocks distributed at Jungwhasandong-Wansandong and Inhudong areas are not schistose granite but gneiss and also that the mean content, the content range and the frequency distribution diagram of trace elements in the metamorphic rock of sedimentary origin and the magmatic granite are different from each other.

Anorthite more contains than albite, it make proof of CaO- K_2O- Na_2O triangular diagram. 3. The manganic oxide trace phenomena are important amusing problem.

      • 黃登 花崗岩의 地質年代測定과 그 成因에 對하여

        南基庠,李鐘德 全北大學校 基礎科學硏究所 1981 基礎科學 Vol.4 No.1

        Hwang-deung granite which is a granitic rock body is connected with Ogcheon formation to the North-east and with so called Hamnasan formation to the North-west. The results that I have examined are as follows; 1. The fo rmation ageof Hwang-deung granite is late Jurassic period. 2. The parent material of Hwang-deung granite is the result of crystallization of the magma which has been formed by the partial melting of earthe crust, not of mantle material.

      • 중등학교 과학교사를 위한 수학적 모델에 관한 연구

        기상,박승태,이영범,이기종,김자홍 全北大學校 科學敎育硏究所 1976 과학과 과학교육 논문지 Vol.1 No.-

        In this paper the relation between science and mathematics has been tested, mathematical expressions in the textbooks have been counted according to the functions such as measure ment or computation, description and evaluation and the number of the expressions has been compared with that in the foreign text books. As a result, we have found that mathemhcal expressions for the purpose of description were the most in the text books, that algebraic formulae were the most among the descriptive expressions, and that algebraic formulae are introduced most in physics and least in biology. Among the contents of mathematics in the text books, simple equation, exponential, logarithm, triangnlation, probability and statistics are used frequeutly, while series or sequence and integration are not very frequently. Some mathematical models for science teachng have been presented after the criteria of the functions. They are consisted of several parts, i.e., statements concerning concepts or theories, questions challenging students, answers and discussions through which students can get intensive concepts. They have been arranged according as the mathematical functions without discrimimating the four fields of science subjects.
