Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone
From Latin basanites + -ite
Fine Grained Rock, Opaque Rock
Black, Brown, Green, Grey, Red, White
Decorative Aggregates, Homes
As Building Stone, Garden Decoration, Office Buildings
Arrowheads, Construction Aggregate, Cutting Tool, Spear Points
As a touchstone, Creating Artwork, Gemstone, In fire-starting tools, Manufacture of tools, Metallurgical Flux, Jewelry, To ignite fire, Used in flintlock firearms
Nepheline-Basanite, Analcite-Basanite and Leucite-Basanite
Clasts are smooth to touch, Easily splits into thin plates, Has High structural resistance against erosion and climate, Used as a touchstone
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.

Ignimbrite is a volcanic rock consisting mainly of pumice fragments, formed by the consolidation of material deposited by pyroclastic flows
From Latin ignis fire + imber, imbr- shower of rain, storm cloud + -ite
Durable Rock, Medium Hardness Rock
Fine Grained Rock, Opaque Rock
Beige, Black, Brown, Grey, Pink, White
Dull, Vesicular and Foilated
Decorative Aggregates, Floor Tiles, Homes, Interior Decoration
As Building Stone, Garden Decoration, Office Buildings, Paving Stone

Artifacts, Monuments, Sculpture, Small Figurines
Cemetery Markers, Commemorative Tablets, Creating Artwork
Always found as volcanic pipes over deep continental crust
Ignimbrites are formed from very poorly sorted mixture of volcanic ash or tuff and pumice lapilli, commonly with scattered lithic fragments.
