remnant material

The remnant materials are highly aluminous and siliceous.

The reached materials dissolved in the surface infiltrates in the weathered surface and cement the silica-aluminous remnant materials.

Kathleen and her mother try to get some remnant material from a fabric store, but Tess O'Hara took every last bit of it for her costume.

This remnant material is diatomite or "Diatomaceous earth", and is used commercially as filters, mineral fillers, mechanical insecticide, in insulation material, anti-caking agents, as a fine abrasive, and other uses.
