rock mantle

The rock mantle in desert pavements protects the underlying material from deflation.

The long period of erosion had resulted in considerable soil formation and most of the rock mantle was covered.

When suitable subterranean space had been carved from the satellite's underlying rock mantle by controlled atomic fire, Holton Lee began building his community.

Great coral reefs formed in these waters, eventually creating the limestone that still makes up about 65 per cent of the rock mantle of the island.

However, she hypothesized that the planet, like all Minshara-class worlds, possessed a molten rock mantle surrounding a liquid metal outer core and a solid inner core composed of metal crystals.

New seismic networks, increasingly sensitive instruments and computers capable of digesting thousands of observations have made it possible for scientists to "look through" the earth's 1,800 miles of rock mantle to the liquid core and its solid kernel, mapping their irregular shape and diverse composition.
