内容記述 | K/Ar and ^<40>Ar/^<39>Ar mineral ages are presented for a variety of rock types from several localities across the high-grade Lutzow-Holm Complex of East Antarctica. Results indicate setting of the K/Ar isotopic system took place between ∿500-450Ma throughout this terrain. These ages represent the time of cooling and stabilization of the region following Pan African orogenic activity as recorded by U/Pb zircon ages. Despite the broad consistency of ages, the results also indicate a significant variation in timing and rate of cooling between localities within the terrain, with average cooling rates being greater in rocks which experienced higher peak metamorphic conditions. | |||||||||
