Formation

Formation
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.   
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.

All about Conglomerate and Scoria Properties

Know all about Conglomerate and Scoria properties here. All properties of rocks are important as they define the type of rock and its application. Conglomerate belongs to Sedimentary Rocks while Scoria belongs to Igneous Rocks.Texture of Conglomerate is Clastic whereas that of Scoria is Vesicular. Conglomerate appears Shiny and Rounded and Scoria appears Glassy and Vesicular. The luster of Conglomerate is dull while that of Scoria is subvitreous to dull. Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors whereas Scoria is available in black, brown, dark grey to black, red colors. The commercial uses of Conglomerate are cemetery markers, in aquifers, tombstones and that of Scoria are as a traction material on snow-covered roads, creating artwork, high-temperature insulation, in gas barbecue grills.
