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

Formation
Jasperoid is a rare and peculiar type of metasomatic alteration of rocks. It is formed by extreme alteration of wall rocks within a shear zone which may occur in sediments, andesites, trachytes and basalts.
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.

All about Jasperoid and Conglomerate Properties
Know all about Jasperoid and Conglomerate properties here. All properties of rocks are important as they define the type of rock and its application. Jasperoid and Conglomerate belong to Sedimentary Rocks.Texture of Jasperoid is Earthy whereas that of Conglomerate is Clastic. Jasperoid appears Glassy or Pearly and Conglomerate appears Shiny and Rounded. The luster of Jasperoid is vitreous and pearly while that of Conglomerate is dull. Jasperoid is available in black, brown, colourless, 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 Jasperoid are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo) and that of Conglomerate are cemetery markers, in aquifers, tombstones.
