莞島地域에 分布하는 深成火成岩類에 대한 岩石學的 및 地球化學的 硏究 = Petrological and Geochemical Study on the Plutonic Igneous Rocks in the Wando Area.

다국어 초록 (Multilingual Abstract)

This study is petrological and geochemical results of plutonic igneous rocks distributed in the wando area.
Plutonic igneous rocks is classified into granitic gnesis, granite, diorite, micrographic granite, quartz-porphry by production state and mineral composition in study area.
The area of granodiorite includes granitic gnesis and granite, that of granite does micrographic granite and quartz pophyry, and that of diorite and gabbro includes diorite by Mode and Norm analyses of them.
Micrographic granite of a kind of plutonic rocks is distributed far and wide in this study area.
Probably micrographic granite is plutonic rocks produced at compressional plate margin and boundary as 61.2% of Calc/Alkaline values.
Micrographic granite includes relative alkali rich or intermediate alkali field by relation chart of alk to al according to the values of Niggli, and is magma type applicable to the area of salic by that of fm to al.
Micrographic granite kinds of is granites of Ⅰ-type by the relation chart of Na_2O and Micrographic granite shows eruption peculiarity of Calc-Alkaline magma by Harkers oxide to sillica variation and AFM figures.
