        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.

        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.

        지리산 서부 일대에 분포하는 편마암류의 미량성분

        남기상,송영미,조규성 한국지구과학회 1991 한국지구과학회지 Vol.12 No.2

        This research aim to geochemical study and the abundance of the trace elements of gneisses distributed in the western region of Mt.Chirisan. Analyzing the trace elements Gke Cu, Cr, Pb, Ni, Co, Mn, Li, Zn for 205 rock samples, and average abundance, range of abundance, frequency of each element were examined. Migmatitic gneiss, metatectic gneiss, porphyroblastic gneiss, granitic gneiss of studied area are lots of average abundance of Cu, Cr, Ni, Co and avidly scattered irregularly frequencies distribution. Also these are very similar to those of shales, therefore, considered to be sedimentary origin. Leucocratic granitic gneiss have lower average abundances in all eight trace elements than those of shales and have similar trace element abundances to those of Namwon granites, therefore, this is igneous origin.

      • 全州片麻巖과 凰山黑雲母花崗巖의 微量成分에 關한 硏究

        남기상,서영교 全北大學校 敎育大學院 1985 敎育論叢 Vol.5 No.-

        The authos analyzed chemically the samples of 12 gneisses and 3 schitose granites distributed in Chonju, 19 granties at Hwangsan in Kim-je and investigated the behavior 5 kinds the correlation and the distribution of it. The results are as follows. 1. The contents of 4 elements of granite except Ni at Hwangsan are less than those of the world average. The reason why the contents of Ni at Hwangsan granite is more than those of the world average is that Hwangsan granite contain a lot the sericite and biotite, so the Ni substitutes for Mg^2+ in camouflage. 2. Though Chonju gneiss and Hwangsan granite has been considered same parent material the author investigated the rock face of Chonju gneiss and analyzed the trace element. The author came to conclusion that it was not same parent material with Hwangsan granite. The distributory range of trace element in Chonju gneiss is wide and the contents of Ni and Cr are more than those of granite average. Therefore the authors came to conclusion that Chonju gneiss were originated from sedimentary rock, and sedimentary rock was metamorphosed because of the intrusion of schistose granite. 3. The correlation of Ni and Cr of Chonju gneiss and Hwangsan granite is very close is that movement condition for major elements of Mg^2+ and Fe^3+ is similar because the physical and chemical property of Ni and is similar, so that Ni and Cr were camouflaged and captured.

        암석의 풍화에 따르는 주요성분의 상대적 이동

        남기상,조규성,Nam, Ki-Sang,Cho, Kyu-Seong 대한자원환경지질학회 1993 자원환경지질 Vol.26 No.1

        This dissertation is a basic research on the degradation of rocks and aims at clarifying the relations between the progression of degree of weathering and the variation of chemical composition. The author wants to make clear the degradation of rocks and the process of formation of sedimentary rocks from a standpoint of elucidation of migration of elements. This study is considered to be significant not only as a part of research on the distribution of earth crust materials but as the petrogenesis of rocks. The chemical studies on the weathered rocks have been started relatively early and there are not a few researches on them: Goldich, 1938; Harris, et al., 1966; Ruxton, 1968; Berner, et al., 1982; Kanuss, 1983; Lasaga, 1984; Siagel, 1984. The degree of migration of elements in weathering is the composite result of various factors. Because, at the present time, it is difficult to clarify the individual and composite effects of each factor theoretically and quanititatively, we must accumulate empirical data and use them relatively. In such consideration the author acquired some data of chemical weathering from the chemical analysis of granitic and basaltic rocks in and around Fukuoka city, Japan and granitic rocks in and around Chonju and Iri cities, Korea. Because both rock types studied can be considered as representative materials of acidic and basic rocks compsing the earth crust, it is significant to examine the phenomena of weathering of both rock types. The following results are obtained from the analysis and examinations of chemical compositions of the original and weathered rocks. The loss rate of major elements has no uniformity, but the following relation holds in general; Ca, Na> K, Si> Mg> Fe, Al. As weathering proceeds, the ratio of $Al_2O_3/CaO$ shows increasing phenomena, and that of $Na_2O/CaO$ decreasing. The range of migration of composition is broad in basaltic rocks but narrow in granitic rocks. The reason is that the chemical weathering of basaltic rocks progresses more easily than that of granitic rocks. The chemical weathering potenitial index of basaltic rocks in larger than that of granitic rocks. The reason is that the chemical weathering of basaltic rocks proceeds more easily than that of granitic rocks. In weathering, the decrease of mobile cations such as $Ca^{2+}$, $Na^{2+}$, $Mg^{2+}$ and the increase of $H_2O$ in basaltic rocks are more obvious than in granitic rocks.

        Weathering of granites has a great geochemical significance, because of their chemical stability near the earth surface which is more pronounced than in most other rocks. The author intended to observe the relative mobility of major elements in weathering process of the granite, distributed on outskirts of Iri city Jeolla-bugdo, Korea. He analysed fresh granites and weathered ones from the Baeg-Gu granite mass and obtained following conclusions in the triangle-diagrams and the oxidized variation diagrams of the samples. 1) The increasing phenomena of $H_2O$ was observed clearly in early and late stages of weathering process. 2) The early stage of weathering is commenced by physical weathering and followed by chemical weathering. 3) The ratio of $FeO/Fe_2O_3$, FeO/MgO, and $SiO_2/Al_2O_3$ decreased uniformly from early to late stage of weathering processes. 4) It was proved that weathering potential of granite was larger than that of basaltic rock. 5) The order of mobility in major elements was Ca, Na and K<Si<Mg<Fe and Al.

        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.
