Tripolitic chert (or tripoli) is a light-colored porous friable siliceous (largely chalcedonic) sedimentary rock, which results from the weathering (decalcification) of chert or siliceous limestone. Siliceous sinter is porous, low-density, light-colored siliceous rock deposited by waters of hot springs and geysers.
