Adakite is an intermediate to felsic volcanic rock that has geochemical characteristics of magma which is said to be formed by partial melting of altered basalt that is subducted below volcanic arcs
From Adak, Aleutian Islands
Durable Rock, Medium Hardness Rock
Fine Grained Rock, Medium Grained Rock, Opaque Rock
Black, Brown, Light to Dark Grey
Decorative Aggregates, Floor Tiles, Homes, Hotels, Kitchens
As Building Stone, As Facing Stone, Office Buildings
As Dimension Stone, Cobblestones, Rail Track Ballast, Roadstone
Monuments, Sculpture, Small Figurines
Commemorative Tablets, Pottery, Used in aquariums
Intermediate volcanic rock
Has High structural resistance against erosion and climate, Host rock for Diamond, Very fine grained rock
Adakite rocks are formed when the hydrous fluids are released from minerals that break down in metamorphosed basalt, and rise into the mantle they initiate partial melting.

Available in Lots of Colors and Patterns, Clasts are smooth to touch
Tachylite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
