Resumen

Phyllite and schist samples from Cape Bowles, Clarence Island, have a greenschist-facies mineralogy. Mineralogy and total rock chemistry suggest a premetamorphic lithology of arenaceous sediments derived from an acid igneous terrain. Rb/Sr isotopic data show that metamorphism occurred during the same late Cretaceous (70-100 m.y.) event recorded elsewhere in the Scotia metamorphic complex and initial ⁸⁶Sr/⁸⁷Sr ratios are consistent with a Mesozoic rather than Precambrian source area. (Authors' abstract) -C.N.
