Under the conditions of metamorphism the calcite in the limestone recrystallizes to form a rock that is a mass of interlocking calcite crystals. A related rock, dolomitic marble, is produced when dolostone is subjected to heat and pressure.

1 Smoke the ribs at 225Â°F to 250Â°F for four to five hours. 2  You can baste or mop the ribs occasionally if you like, but donât open the grill too often. 3  Maintaining a steady temperature is the most important thing.
Cook them for 1.5 to 2 hours, with the meatiest portion downward. Turn the ribs occasionally. If you are using a gas grill, you can ignite one side of the grill and leave the other to cook the ribs. Place the ribs on the side that is not ignited. Grill the ribs for 30 to 45 minutes on each side. If your ribs are too large to cook indirectly on either a charcoal or gas grill, wrap them in heavy duty aluminum foil. Place them on the grill over direct heat for 30 minutes on each side for a gas grill and 30 to 45 minutes each side for a charcoal grill.
