Abstract

Mica concentrated from a post-cleavage lamprophyre occurring at the Prince Lyell Mine, Queenstown, has yielded a K-Ar age of 363±3 Ma (latest Devonian). This minette is the first confirmed evidence of Devonian potassic la mprophyric activity from Tasmania and places an upper constraint on Devonian ductile deformation in western Tasmania.
