Hematite is a common iron oxide mineral that often has a reddish color and consistently produces a red streak when scratched on a white streak plate. Calcite and dolomite are carbonate minerals that do not typically have a reddish color or red streak. Magnetite may have a reddish-brown color, but it can also be black, gray, or brown and does not consistently produce a red streak. Pyrite may have a yellow or brassy color and produces a greenish-black streak, so it is not a good choice for this description.
