Tonalite is a coarse-grained plutonic rock consisting mainly of sodic plagioclase, quartz, and hornblende or other mafic minerals with phaneritic texture
From Tonale Pass, northern Italy, + -ite1
Coarse Grained Rock, Fine Grained Rock, Medium Grained Rock, Opaque Rock
Black, Brown, Light to Dark Grey, White
Decorative Aggregates, Entryways, Flooring, Homes, Interior Decoration
As Building Stone, As Facing Stone, Paving Stone, Garden Decoration, Office Buildings
As Dimension Stone, Cement Manufacture, Cobblestones, Construction Aggregate, for Road Aggregate
Cemetery Markers, Creating Artwork
Is one of the oldest rock, Typically speckled black and white.
When alkali feldspar is extracted from granite, it changes to granitoid and later, it becomes tonalite with quartz as major mineral.

Clasts are smooth to touch, Is one of the oldest rock, Smooth to touch, Very fine grained rock
Diatomite rock formed from the skeletal remains of single celled plants called diatoms. When diatoms die, their skeletal remains sink to the bottom of lakes and oceans etc. hence forming diatomite deposit.
