Conglomerate rock<\/i> is composed of larger gravel particle sizes (larger then sand) with a finer-grained matrix all cemented together.<\/p>\n
C<\/b>onglomerate is made of rounded or semi-rounded rock fragments cemented
\ntogether.\u00a0 The rounding of the fragments implies that the fragments were transported a substantial distance from their source and were abraded in contact with other moving fragments.\u00a0 The rounded fragments were probably deposited along a stream channel or a shoreline.\u00a0 Fragments within a conglomerate are pea-sized and larger. \u00a0An older name for conglomerate is “pudding stone”.<\/p>\n
Conglomerates are classified in terms of both their rounding and sorting.\u00a0 Clast size can range from Boulder, to Cobble to Pebble to Granule.\u00a0 They are deposited in a variety of environments:\u00a0 deep-water marine, shallow marine, fluvial, alluvial, and glacial.<\/p>\n
When a series of conglomerates accumulates into an alluvial fan, the resulting rock is called a fanglomerate<\/i>, which form the basis of large oil fields such as those in the North Sea.<\/p>\n
Spectacular examples of conglomerates can be seen at Montserrat, <\/i>a mountain near Barcelona or near Crestone, CO at the foot of the Sangre de Cristo Range.<\/i>\u00a0 Typically, conglomerate is a coarse, irregular and friable material not well suited as a building stone.\u00a0 However, the Roxbury Conglomerate (Puddingstone) near Boston is well known for its strength.\u00a0 Puddingstone can be cut into blocks for foundations and irregularly shaped stones can be used for field walls.<\/p>\n
