Definition
Foidolite is a rare type of coarse-grained intrusive igneous rock with a feldspathoid mineral content greater than 60%
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix

Etymology
From the mineral feldspathoid which is the main content of rock
From Latin conglomeratus, to roll together, i.e. from com together + glomerare to gather into a ball, from glomus (genitive glomeris) a ball

Archaeological Significance
Formation
Foidolites 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.
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.

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