Marine limestone. Things To Know About Marine limestone.

As nouns the difference between marine and limestone. is that marine is a member of a marine corps while limestone is (mineralogy) an abundant rock of marine and fresh-water sediments; primarily composed of calcite (caco₃); it occurs in a variety of forms, both crystalline and amorphous.
