A single total rock sample of biotite granite from Jule Peaks, Antarctica, has been dated by the rubidium-strontium method at about 3 billion years. The juxtaposition of this sector of Antarctica with Africa in the Dietz and Sproll continental drift reconstruction results in a possible geochronologic fit of the Princess Martha Coast of Antarctica with a covered possible notheastern extension of the African Swaziland Shield, which contains granitic rocks that are also 3 billion years old.
从南极洲朱勒峰采得的一块黑云母花岗岩的单一样本，用铷-锶法测定的年龄约为 30 亿年。南极洲朱勒峰与Dietz 和 Sproll 大陆漂移重建中的非洲并列，使得南极洲玛莎公主海岸与可能覆盖的非洲斯威士兰盾状杂岩东北部延伸部分在地质年代上相吻合，而该延伸部分包含的也是 30 亿年的花岗岩。
