Rubidium-strontium geochronology of plutonic igneous rocks from Hobbs and Walgreen coasts, Marie Byrd Land
Description
Rubidium-strontium (Rb-Sr) radiometric age analyses have been carried out on biotite concentrates and total rock specimens of plutonic igneous rocks. A primary objective of this research was the preparation of geologic maps of Marie Byrd Land at a scale of 1:250,000. Radiometric dating of the ubiquitous igneous rocks was to assist in establishing a chronology of geologic events within Marie Byrd Land for comparison with other circum-Pacific areas of continental lithosphere in Antarctica, South America, and New Zealand
