Kubler Illite “Crystallinity” Index of the Cretaceous Gyeongsang Basin, Korea: Implications for Basin Evolution
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...
