| Abstract | Aliettite, a rare, regularly interstratified talc-smectite clay mineral, occurs at the Olympus mine, Stanleyville, Ontario. The mine was originally developed for its vermiculite, which formed by
hydrothermal alteration of metapyroxenite associated with local thrust faulting. The metapyroxenite generally consists of tremolite and diopside that have been replaced by talc, aliettite, and serpentine. Three stages of hydrothermal alteration are
recorded, 1) replacement of tremolite and diopside by talc and phlogopite, 2) minor oxidation result- ing in Fe-oxide-staining of talc, and 3) serpentinization of the phlogopite. The results suggest that aliettite formed by surface weathering
superimposed upon earlier, low-temperature hydrothermal alteration. |
