• To my eye, it looks like just sandstone or arkose.
• The resulting Cutler red beds are made of iron-rich arkose sandstone.
• Minor basalt flows occur within the Arkose Ridge Formation.
• Arkose is typically grey to reddish in colour.
• The Arapahoe Formation and the Dawson Arkose are also included in the D1 Sequence.
• The Denver Formation and the Dawson Arkose are also included in the D1 Sequence.
• Metamorphic rocks of slate, schist and arkose dominate the northern part of the island.
• It is overlain by the Dawson Arkose.
• This suite consists of metamorphosed siltstone, wacke, conglomerate, arkose, and minor rhyolite.
• The similar mineral composition of the Mutitjulu Arkose and the granite ranges to the south is now explained.
• Locally, quartz diorite or gneiss bodies occur on the arkose-schist contact west of Government Peak.
• Arkose is generally formed from the weathering of feldspar-rich unconformities in the immediate vicinity of granite terrains.
• Fossils are rare in arkose, due to the depositional processes that form it, although bedding is frequently visible.
• Arkose conglomerate and mudstone of the lower Crystal Spring Formation were created from muddy debris derived from stream erosion of these uplands.
• Near Brevik and R鰆da there are diabases dykes hosting numerous rounded clasts of red Jotnian sandstone including both quartz arenite and arkose.
• The Dawson Arkose contains plant remains and other nonmarine fossils, and hosts aquifers that are important sources of water for the area.
• The sand grains making up an arkose may range from fine to very coarse, but tend toward the coarser end of the scale.
• They were thrust up during a Ma ), and thus the Mutitjulu Arkose is believed to have been deposited at about the same time.
• In southern Africa, " Dadoxylon " is widespread in the Pebbly Arkose Formation and also reported frequently from the Angwa Sandstone Formation.
• West of Government Peak, the Arkose Ridge Formation lies to the south of the schist, the contact is a low-angle detachment fault.
