They're significant enough that you might get in trouble with our resident Argentinian (that's a correct guess on your nationality, right, @Krieger-FS?).

I remember there is marble near Lahore on the current map, which didn't make its way to this one. Is there a marble source in Punjab as well, or was this a misplaced source of Makrana marble after all?We should add Makrana marble in NW India. It was very important in construction of the Taj Mahal.
