1.1 Definition

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

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

5 Formation

5.1 Formation

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

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 Conglomerate and Picrite Properties

Know all about Conglomerate and Picrite properties here. All properties of rocks are important as they define the type of rock and its application. Conglomerate belongs to Sedimentary Rocks while Picrite belongs to Igneous Rocks.Texture of Conglomerate is Clastic whereas that of Picrite is Earthy, Rough. Conglomerate appears Shiny and Rounded and Picrite appears Rough and Shiny. The luster of Conglomerate is dull while that of Picrite is subvitreous to dull. Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors whereas Picrite is available in black, brown, colourless, green, grey, pink, white, yellow colors. The commercial uses of Conglomerate are cemetery markers, in aquifers, tombstones and that of Picrite are as a feed additive for livestock, as armour rock for sea walls, metallurgical flux, pottery, source of magnesia (mgo).
