RM2AWDCEE–Annual report . ng several types. A thin section from the dike one milenortheast of Batchellerville shows: 60 per cent lath-shaped plagio-clase (andesine to labradorite) ; 25 per cent hypersthene (faintlypleochroic) ; 10 per cent biotite (much changed to chlorite) ; and 5per cent magnetite (much changed to leucoxene). This rock is atrue hypersthene diabase with the ophitic texture beautifully shown.The dike is about 400 yards long and of varying width up to 100feet. The rock is fine to medium grained, weathers brown on theimmediate surface, shows no sharp contacts, and strikes parallelto the g

The phenocrysts are set in agroundmass which is made up dominantly of irregular plagioclase laths showing albitetwinning lamellae, giving a maximum extinction angle of 20 degrees in the zone normalto the twinning plane. Subordinate quantities of calcite and titanite also occur in thegroundmass. The rock fifty feet south of the large bunkhouse on the OBrien mine is somewhatsimilar to that just described. The thin section, however, shows that it is more decom-posed, and consists of a fine-grained groundmass of chlorite (variety penninite), biotite,titanite,
