What Do You Know About Joliet-Lemont Limestone

Laid down during the Silurian age, about 440-420 million years ago, JLL was formed in the same sedimentary process as other limestone. The difference is that Joliet-Lemont stone is chemically composed of calcium magnesium carbonate [CaMg(CO 3) 2] versus simpler calcium carbonate [CaCO 3].]. JLL is a true dolomite and not just limestone.
