| Research Abstract |
Modeling of Karstification in Minamidaito Island was made. Using solution rate of limestone tablets, following results were obtained:
Present terrain as karstified atoll has been formed during the age of about 1.6Ma.. Result of the dating speleothems showed that lowering of caves at the bottom basin of Minamidaito Island has begun after the years of 100ka. According to the vadose speleothems and the result of borehole studies, lowest sea level was -100m, in the Last Glacial Period. So, it is considered that caves were formed also until -100m a.s.l., in the same period.
