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.
3. Grill the ribs. This is the easy part! Place the ribs over indirect, medium heat on your grill. The temperature should be about 325 degrees F. Cover the grill, and cook the ribs for approximately two hours. Do not check on the ribs for the first 30 minutes â this is crucial! If you open the grill too many times, you put the ribs at risk of drying out. After the two hours are up, use a fork to make sure the ribs pull off the bone easily. If so, they are done.
