Spatial and temporal variations of trace metals in sediments from the artificial Saemangeum Lake, Korea
Saemangeum Lake trace metal spatial distribution pollution status dike
2017/4/11
Trace metals in the surface sediments were measured to investigate the spatial distribution and annual variations of
metals (Cr, Co, Ni, Cu, Zn, As, Cd, Pb, Hg) and to evaluate the pollution status f...

Cretaceous quartz vein mineralogy fluid inclusions stable isotopes mixing
2017/4/11
The Namseong gold and silver deposit is located in the Seolcheon metallogenic province, one of the most important
gold production areas in the Republic of Korea. It consists of three gold and silver-...
Sulfur, oxygen, and hydrogen isotope compositions of precipitation in Seoul, South Korea
sulfur isotope oxygen hydrogen pollution precipitation sulfate Korea East Asia
2017/4/11
To evaluate the source of sulfur and the extent of seasonal and local characteristics in Seoul’s precipitation chemistry,
we measured sulfur, oxygen, and hydrogen isotopic ratios of precipitation. Th...

Gyeongsang Basin Illite Crystallinity (Kübler Index) Korea Low-Grade Metamorphism
2011/12/2
Abstract: Thermal maturity of the Lower Cretaceous Sindong and Hayang groups in the Gyeongsang Basin, Korea, was investigated using the Kübler illite “crystallinity” index (KI) which is based on the n...
Geochemistry and Paragenesis of Heulandite Cements in a Miocene Marine Fan-Delta System of the Pohang Basin, Republic of Korea
Burial Fan-delta Heulandite Cement Heulandite-Clinoptilolite Meteoric Water Sr Isotope Uplift Volcaniclastic
2011/12/8
Abstract: In the Pohang area of Korea, heulandite occurs as cements in conglomerate and sandstone of a Miocene marine fan-delta system resting on Eocene dacitic volcanics. Three types of heulandite ce...
