Formation

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

All about Scoria and Conglomerate Properties

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