Arkose conglomerate.

A feldspar-rich sandstone is called an arkose. Lithic rich sandstones are called litharenites. Further subdivisions are shown in the diagram. If the rock has between 10 and 50% clay matrix, the rock is called a wacke. Quartz wackes have predominantly quartz surrounded by a mud or clay matrix.

The characteristics and distinguishing features of clastic sedimentary rocks are summarized in Table 6.2. Mudrock is composed of at least 75% silt- and clay-sized fragments. If it is dominated by clay, it is called claystone. If it shows evidence of bedding or fine laminations, it is shale; otherwise it is mudstone.

Arkose is normally grey to reddish in colour. The sand grains making up arkose are usually coarse. Arkose is generally formed from the weathering of igneous or metamorphic rocks. These are usually granite rocks, which contain a lot of feldspar and quartz. Arkose is often found with conglomerate deposits where the sediment is made of granite.

Gallery of Feldspars. Feldspars are a group of closely related minerals that together make up the majority of the Earth's crust. All of them have a hardness of 6 on the Mohs scale, so any glassy mineral that's softer than quartz and cannot be scratched with a knife is very likely to be a feldspar. Feldspars lie along one of two solid-solution ...
