Why is some sandstone black, EC? ... in the glacial till parts of this property there is every once in a while a rounded gritty stone that breaks easily, often [but not always] in onion-like layers ... you can take a bigger one and set it by a fence, every year one or two layers will decompose into fine black sand ... this can't be lava, as the form would [to this layman] suggest? ... just guessing, but the colour may come from ferrous or feric oxide, as opposed to the other, which is reddish ... Lots of that roche moutonnée [sp?] on the coast of BC ... looks boring, appropriately named after sheep, doesn't look like there's much of anything in it, the quartz is just bland white
