Ganister, a quartzose sandstone, is usually found in the seatearth, or underclay, that underlies this rock. This rock is "treasured" by paleobotanists because nodules in it can be "peeled" by slicing, etching with acid, coating with acetone, and applying a cellulose acetate film to give a detailed view of fossilized plants, including cell nuclei and chloroplasts. Those nodules are namesake "balls" of petrified plant matter. Like kerogen-bearing shales, its composition can be divided into three maceral groups: inertinite, liptinite, and vitrinite. The rank of this rock increases from its lignite type to its anthracite type and is a measure of its percent amount of carbon. For 10 points, name this rock whose formation begins with the burial of peat.
