Picrite and Conglomerate

1 Definition
1.1 Definition
Picrite is a variety of high-magnesium olivine basalt that is very rich in the mineral olivine
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix

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

All about Picrite and Conglomerate Properties

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