text: The virtual fibers in these layers are oriented in a specific way: In the wall-lining layers that characterize agates, length-fast chalcedony and quartzine virtual fibers run roughly perpendicular to the layers, thus perpendicular to the banding: the individual virtual fibers point away from the wall.
