These sedimentary rocks are also very extensively used as building stones at places of their occurrence but all varieties are not suitable for this purpose. Limestones show great variation in their properties and appearance. Thus in crushing strength, they may be softer than a good brick (less than 200 kg/cm 2) or may be as strong as 1000-1500

Usually hard-rock gold is microscopic and is impossible to collect without advanced milling processes. For example, this piece of milky quartz looks like a plain white rock, but when assayed it ran 14 grams of gold per ton. So in theory, one ton of that rock when milled and processed would yield about one half ounce of gold (assuming 100%
