Genesis and Mineralogy of Serpentinite Deposits,West of South Korea

The serpentinite deposits derived from ultramafic rocks within the South Korea mainly occur in the west of Chungcheongnam-Do, the south of South Korea, Ulsan and Andong area, and in the middle of South Korea, Gapyeong area. The present study is on the genesis and mineral compositions of the serpentinite deposits consisting of about eighteen masses in the west of Chungcheongnam-Do. The ultramafic rocks mainly occur as discontinuously isolated lenticular or elliptical bodies and extend to NNE directions with minor E-W directions. The direction of the major distribution is parallel to the normal or thrust fault lines in the Kyeonggi Precambrian gneiss complex.
