One kind of lung disease (pneumoconiosis): Silicatosis can be caused by breathing in silicate minerals over a period of time. Such minerals can be found in asbestos, talc, and vermiculite, for example.

Pertaining to or resembling silica or silicates; silicaceous: In his geology class, Jim learned that siliceous minerals were found in sandstone, radiolarites or chert.

Pertaining to or derived from silica or silicon: In Doug's chemistry class, he learned about silicic acid that was derived from a substance that contained silicon.
