Stanford researchers have developed an artificial intelligence-based tool—dubbed SandAI—that can reveal the history of quartz sand grains going back hundreds of millions of years. With SandAI, researchers can tell with high accuracy if wind, rivers, waves, or glacial movements shaped and deposited motes of sand.
