内容記述 |
Eight ^<40>Ar-^<39>Ar and six K-Ar ages were determined for igneous and metamorphic rocks collected from the Sør Rondane Mountains, East Antarctica. Biotites from granite and syenite show ^<40>Ar-^<39>Ar ages of about 500 Ma, which are similar to the reported Rb-Sr age. K-Ar and ^<40>Ar-^<39>Ar ages of 440-480 Ma were obtained for igneous dyke samples and metamorphic rocks. ^<40>Ar-^<39>Ar age spectra for K-feldspars, which were separated from the same rocks as biotite, indicate the stair-type patterns. |
