• M203 Conglomerate Stone •
(Alabama)

This specimens make an excellent example of the rock CONGLOMERATE. This conglomerate stone is made up of smooth river pebbles that have been cemented together with an iron oxide material, probably limonite. While most conglomerate rock is of a sedimentary origin, it can also be formed by way of a metamorphic process. The smooth river pebbles are of a variety of quartz such as chert.

Also called Puddingstone or Pudding Stone, conglomerate rock can be formed of a number of different different stones, including sea shells, bonded together with different bonding agents. In these specimens, the pebbles are smooth river rocks and the bonding agent is an iron oxide material It is quite common to find conglomerate stone with other stones cementer together and with different bonding agents. Conglomerate stone is very attractive when cut and polished and is used as tiles, counter tops, building construction and even beads and other jewelry items.

Conglomerate is often much harder and resistant than the sandstones and shales that surround it. Conglomerate is scientifically valuable because the individual stones are samples of the older rocks that were exposed as it was forming-important clues about the ancient environment.
