1.1 Definition

Picrite is a variety of high-magnesium olivine basalt that is very rich in the mineral olivine

Diamictite is a sedimentary rock that consists of non-sorted to poorly sorted terrigenous sediment containing particles that range in size from clay to boulders, suspended in a matrix of mudstone or sandstone

5 Formation

5.1 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.

Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.

All about Picrite and Diamictite Properties

Know all about Picrite and Diamictite properties here. All properties of rocks are important as they define the type of rock and its application. Picrite belongs to Igneous Rocks while Diamictite belongs to Sedimentary Rocks.Texture of Picrite is Earthy, Rough whereas that of Diamictite is Clastic. Picrite appears Rough and Shiny and Diamictite appears Banded. The luster of Picrite is subvitreous to dull while that of Diamictite is grainy, pearly and vitreous. Picrite is available in black, brown, colourless, green, grey, pink, white, yellow colors whereas Diamictite is available in brown, buff 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 Diamictite are commemorative tablets, creating artwork, production of lime.
