Definition
Tonalite is a coarse-grained plutonic rock consisting mainly of sodic plagioclase, quartz, and hornblende or other mafic minerals with phaneritic texture
Oolite is a sedimentary rock formed from ooids, spherical grains which are composed of concentric layers of calcite

Archaeological Significance
Formation
When alkali feldspar is extracted from granite, it changes to granitoid and later, it becomes tonalite with quartz as major mineral.
Oolites form when layers of calcite are deposited around a sand grain or fossil piece and are rolled around in calm water, which makes them round.

All about Tonalite and Oolite Properties
Know all about Tonalite and Oolite properties here. All properties of rocks are important as they define the type of rock and its application. Tonalite belongs to Igneous Rocks while Oolite belongs to Sedimentary Rocks.Texture of Tonalite is Phaneritic whereas that of Oolite is Clastic or Non-Clastic. Tonalite appears Banded and Foilated and Oolite appears Rounded and Rough. The luster of Tonalite is subvitreous to dull while that of Oolite is pearly to shiny. Tonalite is available in black, brown, light to dark grey, white colors whereas Oolite is available in black, blue, brown, cream, green, grey, pink, red, silver, white, yellow colors. The commercial uses of Tonalite are cemetery markers, creating artwork and that of Oolite are creating artwork, jewelry, used in aquariums.
