영문 초록

K-Ar ages were determined on gangue and wall rock alteration minerals from twenty metallic mineral deposits in the Gyeonggi Massif. Beryl deposits give the age of 185 Ma, whereas tungsten - molybdenum deposits reveal two different age groups such as 172~156 Ma and 91~86Ma. Lead - zinc deposits and gold - silver deposits yield the ages of 160 Ma and 71~197 Ma, respectively. Mineralization ages for each genetic type of deposits in the Gyeonggi Massif can be summarized as follows; pegmatite deposits, 185 Ma; skarn deposits, 156~160 Ma; hydrothermal deposits, 71~197 Ma. Present results together with data previously reported reveal that rare earths, tungsten-molybdenum, base and precious metal deposits in the Gyeonggi Massif were formed in Jurassic and Cretaceous time with a genetic relationship to the Daebo and Bulguksa felsic igneous activity.
