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 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.

The author intended to observe the relative mobility of elements in weathering processes of granitic rocks, extending over the whole district of Jeonbug Korea. He analysed fresh granitic rocks and weathered rocks, and had following conclusion by the trianguar diagrams and oxidized variation diagrams of the analysis. 1) The increasing phenomena of H_2O observed cleaved in early stage and late stage of weathring processes. 2) The ratio of Feo/Fe/O_3, FeO/MgO, and SiO_2/Al_sO_3 decreased uniformly from early to late stage of weathering processes. 3) The order of weathering potential was basaltic rocks>quartz porphyry>granite rocks. 4) The order of mobility in major elements was Ca, Na, K, >Si>Mg>Fe^3+………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.

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.

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.

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.
