남원군 산내면 일대에 분포하는 편마암류의 미량성분에 의한 그 기원암에 관한 연구 = Study on the Original Rocks of the Gneisses by Trace Elements in Sannae Area, Namwon

다국어 초록 (Multilingual Abstract)

This research aims to study origin by trace elements (Cu, Cr Pb, Ni, Mn, Li,Zn) of 225 samples of the gneisses that receive high metamorphism in sannae-myeon area, Namwon-gun. I have studied average abundance, abundance range and frequency distribution of each elements, and considered geochemical feature of the trace elements in the shale and granite.
Abundance of Cu, Cr, Ni, in the shale of sedimentary origin is higher than that in the granite of igneous origin. Abundance of the trace elements in the porphyroblastic gneiss, granitic gneiss and pegmatitic gneiss is very similar to the that in the shale with the biotite gneiss, but that in the leucocratic gneiss is less than in the shale and it is similar to the granite.
Frequency distribution of the rocks of sedimentary origin is irregularly widely dispersion, but that of igneous origin is distributed narrowly around maximum frequency.
Therefore the porphyroblastic gneiss, granitic gneiss and pegmatitic gneiss is paragneiss with the biotite gneiss, and the Leucocratic gneiss is orthogneiss. This result is in accord with geological field survey and study on the metamorphism(Kim O.J. etal.,1964;Kim H.S., 1970,1973; Lee S.M., 1980,1981)
