A coarse-grained rock and a fine-grained rock probably had different what?
Methods of formation. If crystalline (igneous or metamorphic) they would most likely have had differing rates of cooling. If sedimentary, they would most likely have had differing depositional environments (higher energy for larger grain sizes).
