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.

Websterite is ultramafic and ultrabasic rock that consists of roughly equal proportions of orthopyroxene and clinopyroxene. It is a special type of pyroxenite.
From the town of Webster located in North Carolina

Generally rough to touch, Is one of the oldest rock
Websterite can be formed as cumulates in ultramafic intrusions by accumulation of pyroxene crystals at the base of the lava chamber.
