	Olympus Microscopy Resource Center: Polarized Light Microscopy Gallery - Arkose
		Arkose is a coarse sandstone rich in feldspar that typically exhibits a pink, gray, or reddish hue.
		The substance closely resembles granite, the rock from whose disintegration it is commonly derived, in appearance and is frequently utilized as a building material.
		Quartz is the principal material in arkose, but feldspar composes at least 25 percent of the material, and calcite, iron oxide, and micas may be present as well.

	Uluru - Kata Tjuta National Park: Geology
		Uluru rock is composed of arkose, a course grained sandstone rich in the mineral feldspar.
		The sandy sediment, which hardened to form this arkose, was eroded from high mountains composed largely of granite.
		The alluvial fans of arkose and conglomerate were at least 2.5km thick and were gradually covered by sand and mud and the remains of sea creatures.

	Uluru and Kata Tjuta (Site not responding. Last check: )
		Though uniformitarian (slow-and-gradual) geologists believe the arkose and conglomerate were deposited ‘relatively rapidly’, they still allow up to 50 million years for the occasional flash floods to have scoured the mountain ranges south and west of the Uluru area and carried the rubble many tens of kilometres out on to the adjoining alluvial flats.
		If the arkose was deposited as sheets of sand only centimetres (an inch or two) thick spread over many tens of square kilometres to dry in the sun’s heat over countless thousands of years, then the feldspar crystals would have decomposed to clays.
		Since the layers of arkose and conglomerate are now tilted, the arkose almost vertically, it is also obvious that after being deposited these sediment layers were compressed and began to be cemented (hardened) while still water-saturated, and then pushed up by earth movements.

		Except for a few small blocks embedded in the arkose layers, all the boulders lie in a matrix of massive dark greenish-gray mudstone, containing fine flakes of mica, grains of rotten feldspar, and a few wood fragments.
		In places the arkose is pebbly, and rarely small boulders are embedded in it.
		In places the arkose layers merge into lenses of chert and limestone breccia 5 to 10 feet thick, consisting of closely packed angular fragments 6 inches or less across with a small amount of interstitial arkosic matrix.

	Arkose
		Arkose is said to be an immature rock because of its high feldspar content.
		The sediment that forms this rock must be deposited rapidly or in an arid environment to prevent the feldspar from decomposing.
		Most arkoses are terrestrially derived from granite disintegration.

		The arkose layers in the member rise in low knobs and hogbacks, but the boulder-bearing mudstones are mostly worn down to valleys and lowlands.
		Here the main arkose layers underlie the boulder bed and there is only one mudstone layer, which pinches out between sandstones and shales 2 miles south of the railroad.
		Probably the mudstone of the southwestern exposures, like that of the northeasternmost, is correlative with the middle part of the boulder-bed member near Housetop Mountain, and the lower arkoses connect with the thin arkose layers between the lower mudstone members farther north.

	arkose
		A detrital sedimentary rock formed by cementation of individual grains of sand size and predominantly composed of quartz and feldspar.
		A feldspar-rich sandstone, typically coarse-grained and pink or reddish, that is composed of angular to subangular grains that may be either poorly or moderately well sorted; usually derived from the rapid disintegration of granite or granitic rocks, and often closely resembles granite; e.g., the Triassic arkoses of the Eastern United States.
		Arkose may also occur at the base of a sedimentary series as a thin blanketlike residuum derived from and resting on granitic rock.

		Situated 335 km south-west of Alice Springs in the Northern Territory, this large rock mass is an erosional remnant made of a sedimentary rock, a feldspar-rich sandstone called arkose.
		The arkose has impurities of iron oxide, so there are strong red and brown colours in the rock.
		The present smooth outline is the result of spalling, where sheets of rock have peeled off as a result of expansion and contraction from continual heating and cooling.

		The caliches within the Hartford Basin are mainly in fluvial sequences of the New Haven Arkose.
		The New Haven Arkose consists of 2000 meters of sandstone and red mudstone that make up the lower portion of the approximately 4000 meter thick clastic fill of the basin (Wang et al.
		The gleyed areas are not all filled with calcite but since they have a similar geometry to areas that are filled with calcite we interpret that the fluid responsible for this diagenesis was reducing (so Fe is leached) and supersaturated with respect to calcite.

	Deerfield Rift Basin, Massachusetts
		The basal unit, the Sugarloaf Arkose (~2000 m), is primarily a red pebbly to conglomeratic fluvial and alluvial arkose.
		This suggests that the source of the clasts in the arkose was low to medium grade metamorphic rocks structurally high in the Acadian nappes that have since been removed by erosion.
		The induration of the arkose may be a consequences of cements generated from the overlying Early Jurassic age lacustrine strata, either during deposition or early diagenesis.

	Uluru and Kata Tjuta: a testimony to the Flood
		The layers of Uluru Arkose and Mount Currie Conglomerate, which had been buried by hundreds or even thousands of metres of younger Amadeus Basin sediments, were strongly folded and faulted (Figure 4C).
		Likewise, if the arkose had been exposed to the destructive forces of erosion and tropical deep chemical weathering even for just a few million years, as is claimed, then the feldspar crystals would have long ago decomposed to clays.
		Even geologists who believe in slow-and-gradual sedimentation over millions of years have to admit that the waters which carried such large boulders (some over 1.5 metres or five feet across) had to be a swiftly-flowing, raging torrent.
