👉 Quartziferous is a geological term that describes rocks that are made up of quartz crystals. Quartz is a mineral that is found in many different types of rock, including sandstone and limestone. These rocks can be very hard and strong, but they also have a distinct texture and appearance due to the presence of small grains of quartz crystal. The term "quartziferous" comes from the Greek word "quarta," which means third or fourth.
