Question

Quizplus · Accepted Answer

Limestone and dolomite are both carbonate rocks, which means they are already composed mainly of calcium carbonate. This makes them susceptible to carbonation, which is the reaction between mineral carbon dioxide and water that forms carbonic acid. This process can dissolve and alter the limestone or dolomite, causing it to erode and weather more quickly. Sandstone, granite, basalt, gneiss, slate, shale, and conglomerate are not composed primarily of calcium carbonate and are therefore less susceptible to carbonation.
