Archaeological Significance
Formation
Picrite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

All about Picrite and Monzogranite Properties
Know all about Picrite and Monzogranite properties here. All properties of rocks are important as they define the type of rock and its application. Picrite and Monzogranite belong to Igneous Rocks.Texture of Picrite is Earthy, Rough whereas that of Monzogranite is Porphyritic. Picrite appears Rough and Shiny and Monzogranite appears Veined or Pebbled. The luster of Picrite is subvitreous to dull while that of Monzogranite is dull to grainy with sporadic parts pearly and vitreous. Picrite is available in black, brown, green, grey, pink, white, yellow colors whereas Monzogranite is available in black, grey, orange, pink, white colors. The commercial uses of Picrite are as a feed additive for livestock, as armour rock for sea walls, metallurgical flux, pottery, source of magnesia (mgo) and that of Monzogranite are cemetery markers, commemorative tablets, creating artwork, curling, tombstones.
