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

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.

Whiteschist is an uncommon rock type belonging to a class of metamorphic rock, this is formed at high-ultra-high pressures
From French schiste, Greek skhistos i.e. split

High percentage of mica, Host Rock for Lead
Whiteschist is formed by dynamic metamorphism at high temperatures and pressures that aligns the grains of mica, hornblende and other elongated minerals into thin layers.
