Arkose grain size.

The disseminated chalcopyrite within the arkose resembles that seen in sediment hosted deposits in that it occurs as interstitial grains which are similar in size to the arkose grain size. In places it appears to follow a preferred banding which may be bedding, although it could equally be a fracture set.Wild rice isn’t actually rice, but it is Minnesota’s state grain.
