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...
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-...
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...
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...
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...
Abstract: Illite crystallinity and fluid inclusion techniques are used to understand the thermal histories of rocks on either side of the disconformity between the Lower and Upper Paleozoic strata in ...
An X-ray diffraction study of vermiculitized micas in ultramafic and mafic intrusive rocks from Cheongyang, Korea, shows the following weathering sequence: mica → ordered mica/vermiculite interstratif...
Abstract: Boxwork fabric in which numerous thin or thick halloysite wails are interconnected into a microscopically porous cellular pattern is widely developed in the halloysite-rich kaolin formed by ...
