NASA Space Photo Highlights Zimbabwe’s 2.5-Billion-Year Great Dyke
NASA’s astronaut photo from the ISS showcases Zimbabwe’s Great Dyke—a 2.5-billion-year-old lopolith that runs about 550 kilometers through central Zimbabwe. Rich in platinum, chromite, copper, iron, and nickel, the Dyke is both a major mineral resource and a window into Earth's early tectonic history; space-based observations help map its extent and monitor changes impacting mining and the environment.
