Orbital‐ and millennial‐scale climate and vegetation changes between 32.5 and 6.9k cal a BP from Hanon Maar paleolake on Jeju Island, South Korea
ABSTRACT Orbital‐ and millennial‐scale climate and vegetation changes between 32.5 and 6.9k cal a BP from Hanon Maar paleolake on Jeju Island, Korea, were demonstrated by high‐resolution multi‐proxy data (pollen, magnetic susceptibility, total organic carbon, carbon/nitrogen ratios and sediment grai...
