Archaeological Significance
Formation
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.
Hornblendite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

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