Arenite is a sedimentary rock.
Many of the island's rocks have been identified as relatively quartz-rich arenites.
The sediment is mostly quartz arenite.
Six sandstone names are possible using descriptors for grain composition (quartz-, feldspathic-, and lithic-) and amount of matrix (wacke or arenite).
The arenite can contain calcareous concretions, fossils and hardgrounds with shell fragments.
Sand composition is largely quartz arenite and a small percentage of monomineralic components dominated by quartz and some accessory minerals (zircon, feldspar, hematite, and rutile).
The term quartzose sandstone can also be used for a quartz arenite.
Beds of very fine to very coarse, rarely gravelly, sandstone (volcanic lithic arenite) and mudstone dominate the succession with beds of lithic and vitric tuff occurring at two horizons.
Beds of very fine to very coarse, sandstone (volcanic lithic arenite) and mudstone dominate the succession with a bed of lithic and vitric tuff occurring at one horizon.
Beds of very fine to very coarse, rarely gravelly, sandstone (volcanic lithic arenite) and mudstone dominate the succession with subordinate beds of lithic and vitric tuff.
