Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix
Hyaloclastite is an aggregate of fine, glassy debris formed by the sudden contact of hot, coherent magma and cold water or water-saturated sediment

Formation
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.
Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.

All about Conglomerate and Hyaloclastite Properties
Know all about Conglomerate and Hyaloclastite properties here. All properties of rocks are important as they define the type of rock and its application. Conglomerate belongs to Sedimentary Rocks while Hyaloclastite belongs to Igneous Rocks.Texture of Conglomerate is Clastic whereas that of Hyaloclastite is Pyroclastic. Conglomerate appears Shiny and Rounded and Hyaloclastite appears Dull. The luster of Conglomerate is dull while that of Hyaloclastite is dull and grainy. Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors whereas Hyaloclastite is available in brown, grey, yellow colors. The commercial uses of Conglomerate are cemetery markers, in aquifers, tombstones and that of Hyaloclastite are cemetery markers, creating artwork.
