Overview

Reevesite is a rare nickel-iron hydroxycarbonate mineral with the chemical formula Ni6Fe^3⁺2(OH)16(CO3) * 4H2O. It crystallizes in the trigonal crystal system and belongs to the Strunz classification 5.DA.50.

Etymology

Reevesite is named after Frank M. Reeves, in recognition of his contributions to mineralogy. The mineral was approved by the International Mineralogical Association (IMA).

How to recognize it

Reevesite can be identified by its very low Mohs hardness of 2, which makes it easily scratched by a fingernail. It has a yellow streak and a dull to earthy luster. Its low density and yellow to greenish color also aid in identification. Due to its rarity and softness, it is often confused with other soft, yellow-colored minerals, but its streak and chemical composition help distinguish it.

Trivia

Reevesite is notable for its extremely low hardness of 2 on the Mohs scale, making it one of the softer minerals. Its chemical formula includes both nickel and iron in the +3 oxidation state, which is a rare combination in mineral structures. The mineral is also distinguished by its unique trigonal crystal system and the inclusion of four water molecules in its structure.
