New Red Sandstone Formation

The New Red Sandstone Formation is a geological rock layer primarily made of sandstone that has a reddish hue. It was formed millions of years ago through the accumulation of sand deposits in ancient rivers, deserts, or coastal areas, which then solidified over time into rock. Its distinctive red color comes from iron oxide (rust) within the sandstone. This formation is significant because it preserves fossils and clues about Earth's past environments, often used to study ancient climates and biological history. It appears in various parts of the world, notably in regions like Australia and parts of the UK.
