조규성,남기상 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.

This research aims to study and compare with the trace elements between gneissic rocks and granitic rocks distributed in the ares of Namwon county. The characteristics of trace component which discriminate the origin rock of gneiss from others are as follows: 1. When the origin rock of gneiss is sedimentary origin, Mn, Co, Ni, Cr, Cu, etc. as their trace elements contain 2-4 times of igneous origin. 2. This fact is consistent with the chemical phenomenon of the environment of sediment, that is, it is well consistent with the trace elements of sedimental phenomenon in the lower deepsea. 3. In the distributed frequency of the trace elements, the distributed frequency of the origin of sediment occupies widlier than that of the origin of igneous. 4. The results I found will be more certain by the accumulation of data added, and they will contribute to the study of origin rock of gneiss.

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.

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.

Based on the opinions of earth science teachers obtained by questionnaire methods(Nov.1983-Feb.1984) and, the analyses of curricula and textbooks (domestic and foreign), 44 laboratory activities for high school earth science were selected as main or important items, among which 21 were proposed as essential ones. Some items were application-tested in the attached high school. Selection was filtered through the seven criteria of selection, two most important ones of which are as follows: laboratory activities should be 1) free of temporal and spatial restrictions, and 2) directed to real objects (earth and universe), not to models, if possible. Domain of concern of earth science was divided by four main fields such as geology, atmospheric science, oceanography and geophysics,and astronomy, so that laboratory activities were grouped accordingly. For 44 items short remarks are tabulated of the methods of implementation, while for ten essential ones detailed description is presented. Situations in high schools and some propositions in relation to the laboratory activities are discussed.

The Bibong coal field, lying between 127˚ 07' 30' E-127˚ 12' 30' E in longitude and 36˚ 00'00' N-36˚ 02' 30' N latitude, is located in Wanju-Gun Jeolabug-Do. The topograpty of coal field, occuping the north-east part of the Jeonju city, shows very ruged and steep features. The coal field consist of metamorphic rocks of Palaeozic and Mesozoic, and some igneous rocks of Jurassis period. The metamorphic rocks, known as part of so-called Ogcheon system, outcrop on widely scale in this area. The characteristics of the coal field are as follows. 1. The geology of the coal field shows congromerate, schist, coal seam, limestone and quartzite from the bottom which are intruded by mesozoic biotite granite. 2. The formations at the coal field strike N30˚E∼N60˚E form the repeated isoclinal fold with 50˚∼ 70˚NW of axis dip. 3. The coal seams of the field are present at the top of the coal bearing strata distributed widely due to the fold structure, among which 2 or 3 seams are minable. 4. Both the low-quality coal (2,500∼4,000cal/g) and the high-quality one (4,800-6,300cal/g) are mines at the same coal field. 5. The chiastolite present in the coal bearing strata may be minable when both the quality and quantity are considered. 6. Carbonization relations between water and volalitity are age of it's sedimentation.

Weathering of granite has a geochemical role of great significance, because of their abundance and because of chemical instability near the surface of the earth, which is more pronounced than in most other rocks. Therefore, the writer has studied on the weathering of plagioclase part of granite. The observation are as follows. 1. At the beginning stage of weathering, various shapes factor by chemical erosion appear on the plagioclase such as etch pits, conical hollows and squre holes. 2. In the next stage of weathering, creation of imogolite, gibbsite and halloysite.

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.

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.
