Puddingstone is a type of sedimentary rock which first formed in river channels. The white is quartz sand which has cemented itself together over millions of years. Mixed with it is a combination of other pebbles and stones of various sizes, shapes and colors. Some may even contain fossils. Another name for puddingstone is quartz conglomerate, meaning sedimentary rock composed of quartz and various other minerals. Minerals contained within the rock may also vary. In some puddingstones minerals such as chromite, corundum, platinum, diamonds, gold, sapphire, and zircon have been found. Tightly cemented puddingstones make a good ornamental stone when cut and polished properly. |
