Arkose is sandstone with significant amounts of feldspar, usually greater than 25%. Sandstone that contains feldspar, which weathers more quickly than quartz, is useful for analyzing the local geologic history. Greywacke is a term with conflicting definitions .

Cranberry Granite (Precambrian) at surface, covers 13 % of this areaArkose. Arkose is a detrital sandstone that contains at least 25% feldspar. It includes felsic arkose and lithic arkose. Arkose usually forms in areas of strong tectonic movements and dry and cold climates, where the parent rock is granite or granitic gneiss. Arkose forms due to physical weathering, severe erosion and rapid deposition of quartz ...

Conglomerate. Conglomerate is a sedimentary rock formed by the lithification of rounded or sub-rounded gravel (grains larger than 2 mm in diameter). Conglomerate is strongly related to sandstone.

Feldspar alters to clay with chemical weathering and erosion, so arkose, which is sandstone with more than 25% feldspar, indicates the sediment was deposited close to the source rock and was not in transport long. Grain size and shape and composition can indicate the composition, distance, and height of the source rock.

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.
