Definition
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix
A water-soluble mineral sediment resulting from concentration and crystallization by evaporation from an aqueous solution

Archaeological Significance
Formation
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.

All about Conglomerate and Evaporite Properties
Know all about Conglomerate and Evaporite properties here. All properties of rocks are important as they define the type of rock and its application. Conglomerate and Evaporite belong to Sedimentary Rocks.Texture of Conglomerate is Clastic whereas that of Evaporite is Earthy. Conglomerate appears Shiny and Rounded and Evaporite appears Glassy, Vesicular and Foilated. The luster of Conglomerate is dull while that of Evaporite is subvitreous to dull. Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors whereas Evaporite is available in green, grey, silver, white colors. The commercial uses of Conglomerate are cemetery markers, in aquifers, tombstones and that of Evaporite are used in the manufacture of ceramic powder, used in the preparation of sulfuric acid and silicon diborite.
