Marl: Past and Present

Marl is a product in the ground of historic natural forces, typically found where coastlines or shallow bodies of water once existed. It is found in various colors, often greenish, with a number of key mineral ingredients and other characteristics that were valuable to farmers, and later, to chemists. It often contains fossils of ancient creatures, and can tell significant historic stories about the evolution of life on earth.
