Arkose is a type of sedimentary rock characterized by its high mineral content of feldspar, particularly orthoclase. It is often considered a type of sandstone, but its distinctiveness lies in the abundance of feldspar grains, which typically make up at least 25% of the rock. The term "arkose" is derived from the Greek word "arkos," meaning …

Hematite and magnetite are two common iron-oxide minerals. Most iron ore deposits consist mainly of hematite, magnetite, or both. Iron-oxide concretions, iron-oxide nodules, and ironstones are often mistaken for meteorites because they are heavy (dense) and their unusual (frequently bizarre!) shapes catch people's attention.
