Formation
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.
Chalk is formed from lime mud, which accumulates on the sea floor which is then transformed into rock by geological processes.

All about Conglomerate and Chalk Properties
Know all about Conglomerate and Chalk properties here. All properties of rocks are important as they define the type of rock and its application. Conglomerate and Chalk belong to Sedimentary Rocks.Texture of Conglomerate is Clastic whereas that of Chalk is Clastic or Non-Clastic. Conglomerate appears Shiny and Rounded and Chalk appears Soft. The luster of Conglomerate and Chalk is dull. Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors whereas Chalk is available in grey, white, yellow colors. The commercial uses of Conglomerate are cemetery markers, in aquifers, tombstones and that of Chalk are alumina refineries, creating artwork, drawing on blackboards, gymnasts, athletes and mountain climbers use for grip, in aquifers, paper industry, production of lime, raw material for manufacture of quicklime, slaked lime, soil conditioner, whiting, whiting material in toothpaste, paint and paper.
