Arkose conglomerate
Estimated to be about 1,400 ft thick. Upper half can only be seen on Green Mountain. Lithologically variable. Lower part is an alternation of conglomerate, grit, sandstone, sandy clay and clay. Upper part predominately coarse conglomerate with minor clay and sandy beds. Pebbles in the conglomerates rarely exceed 3 inches in diameter.A feldspar-rich sandstone is called an arkose. Lithic rich sandstones are called litharenites. Further subdivisions are shown in the diagram. If the rock has between 10 and 50% clay matrix, the rock is called a wacke. Quartz wackes have predominantly quartz surrounded by a mud or clay matrix.The quartz arenite and arkose have relatively little silt-clay matrix, while the lithic wacke has abundant matrix. Clastic sedimentary rocks in which a significant proportion of the clasts are larger than 2 millimetres are known as conglomerate if the clasts are well rounded, and breccia if they are angular. Conglomerates form in high-energy ...

Conglomerate. Conglomerate is a sedimentary rock formed by the lithification of rounded or sub-rounded gravel (grains larger than 2 mm in diameter). Conglomerate is strongly related to sandstone. It is actually a type of sandstone, although it may not be technically correct to say so. Conglomerate is composed of clasts larger than 2 mm (sand is ...It includes conglomerates at the type locality, landslide deposits within the conglomerate, and sandstone and lake beds above the slump zone unconformity, which were formerly included in the Turners Falls Sandstone.
