Explore: Spherules (geology)

Martian spherules (also known as hematite spherules or blueberries) are small spherules (roughly spherical pebbles) that are rich in an iron oxide (grey

creates a by-product known as "lightning-induced volcanic spherules" (LIVS). These tiny glass spherules form during high-temperatures processes such as cloud-to-ground

The geology of Mars is the scientific study of the surface, crust, and interior of the planet Mars. It emphasizes the composition, structure, history

fused sediments into small glassy spherules. Spherules of 3.5 billion years old exist in South Africa, and spherules of a similar age have been found in

hematite spherules with their distinct composition (not found at Gusev Crater, Ares Vallis, and Gale Crater). This layering of spherules (and spherule fragments)
