The Tertiary sandstone ( Cuddalore Formation ) comprise pinkish, yellowish, reddish ( variegated colours ) medium to coarse grained sandstone and clay stone.

Coarser grained rocks tend to yield less well developed shatter cones, which may be difficult to distinguish from other geological formations such as slickensides.
43.
Thermal metamorphism of the country rock in the contact zone produced coarse grained marbles within the aureole in a small number of places in Teesdale.
44.
The dolerite is coarse grained in the main, often equigranular and holocrystalline although porphyritic areas are known and chilled margins and occasional compositional variations are noted.
45.
Kata Tjuta's domes are the eroded remains of sedimentary rock from the seabed, while Uluru is a relict of the coarse grained, mineral-rich sandstone called arkose.
46.
However this would have been at the expense of a coarser grained network, with much longer distances between U-Bahn stations than between the tram stops they replaced.
47.
The dunes form at about ninety degrees to the prevailing wind which blows away the small, fine-grained sand leaving behind the coarser grained sand to form the crest.
48.
Discordantly overlying the Lower Eocene is the Middle Eocene Regadera Formation; quartzitic and feldspar rich thick medium to coarse grained to conglomeratic sandstone beds intercalated with thin pink claystones.
49.
This is overlain by an easily identified very coarse grained sandstone known as the Top Ashdown Pebble Bed, which is considered to be part of the overlying Wadhurst Clay Formation.
50.
Throughout most of the P . M . & B . quarry the limestone has a uniform fine grain, with only a few irregular patches of coarser grained and crystalline stone.
