Abstract
Illite is the most abundant clay muneral in the marine surface sediments around the Korean Peninsula. We studied the mineralogical characteristics of illite such as Kubler index (KI) and intensity ratio (IR), using 33 surface sediments which were collected at Northwest Mudbelt deposit (NWMD, 17 samples), South Sea of Korea Mudbelt deposit (SSKMD, 3 samples), Hucksan Mudbelt deposit (HSMD, 2 samples) and Jeju Mudbelt deposit (JJMD, 11 samples). Illite has very low KI (0.14-0.16) and wide range of IR (1.15-1.90) in the JJMD, medium to high KI (0.32-0.44) and IR (1.46-1.95) in the SSKMD and HSMD, and wide range of KI (0.28 - 0.58) and IR (1.08 - 1,70) in the NWMD. In the NWMD, KI and IR have positive relationship in the NWMD. Generally series 1 is distrubuted in eastern part, series 2 is in western part, and series 3 is in central part of NWMD. Each series might stand ofr different sediment provenance.
