Formation
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.
Essexite is a type of igneous rock, which is usually dark grey to black plutonic rock. For the formation of essexite, suitable magma with exact composition of K, Ba, Rb, Cs, Sr should be produced.

All about Conglomerate and Essexite Properties
Know all about Conglomerate and Essexite properties here. All properties of rocks are important as they define the type of rock and its application. Conglomerate belongs to Sedimentary Rocks while Essexite belongs to Igneous Rocks.Texture of Conglomerate is Clastic whereas that of Essexite is Granular. Conglomerate appears Shiny and Rounded and Essexite appears Banded. The luster of Conglomerate is dull while that of Essexite is not available. Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors whereas Essexite is available in dark grey to black colors. The commercial uses of Conglomerate are cemetery markers, in aquifers, tombstones and that of Essexite are cemetery markers, commemorative tablets, jewelry, sea defence, tombstones.
