Feb 6, 2010 A small ventifact of arkose sandstone with large light phenocrysts of feldspar and small dark green spots of quartz. Arkose is a sedimentary rock. It may also contain some calcite cement, which can cause this type of sandstone to "fizz" when exposed to dilute hydrochloric They formed in colluvium derived from granite, gneiss, and arkose sandstone.

Arkose is a sedimentary rock, specifically a type of sandstone containing at least 25% feldspar. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks.

Commercial uses of Arkose: in aquifers, soil conditioner, source of magnesia (mgo), tombstones. Sandstones are divided into three main groups: Arkosic sandstones have a high (greater than 25 per cent) feldspar content and a composition similar to granite. Quartzose sandstones (beach sand) have a high quartz content (greater than 90 per cent). Argillaceous sandstones contain a significant level Arkose is a sedimentary rock, specifically a type of sandstone containing at least 25% feldspar.
