| Abstrakt: | The abundances of Sc, rare earths, Zr, Hf, Ta and Th were determined in five New England granitic plutons. Similar data are reported for separated minerals from three of the units. The granites can be divided into the Massachusetts alkaline group (Cape Ann, Peabody, Quincy) and the Rhode Island subalkaline group (Narragansett Pier, Westerly). |
