Definition

Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix

Tonalite is a coarse-grained plutonic rock consisting mainly of sodic plagioclase, quartz, and hornblende or other mafic minerals with phaneritic texture

Formation

Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.

When alkali feldspar is extracted from granite, it changes to granitoid and later, it becomes tonalite with quartz as major mineral.

All about Conglomerate and Tonalite Properties

Know all about Conglomerate and Tonalite properties here. All properties of rocks are important as they define the type of rock and its application. Conglomerate belongs to Sedimentary Rocks while Tonalite belongs to Igneous Rocks.Texture of Conglomerate is Clastic whereas that of Tonalite is Phaneritic. Conglomerate appears Shiny and Rounded and Tonalite appears Banded and Foilated. The luster of Conglomerate is dull while that of Tonalite is subvitreous to dull. Conglomerate and Tonalite are available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors. The commercial uses of Conglomerate are cemetery markers, in aquifers, tombstones and that of Tonalite are cemetery markers, creating artwork.
