It looks like a piece of sedimentary rock that underwent some metamorphosis. The dark band could be an old layer of black sand magnetite, or perhaps it is a layer of pyroxine or augite grains from the decomposition of granite. But to really figure it out will take some careful testing and observation. I see that the upper boundary of the dark mineral is very sharp, as if it were basalt injected into a fissure, but the lower boundary seems to fade into the other kind of rock. ???

Yup...my thoughts exactly.  [&whistle#]

Veins of magnetite were found in the port renfrew area. They were drilling on a few veins
