Fuenzalidaite is a rare mineral species found in Chile. The word is pronounced as /fu.en.za.li.daɪt/ with emphasis on the second syllable (en). The spelling of the word follows the standard English phonetic rules, with the letter "z" pronounced as /z/ and the "d" and "t" sounds formed by the combination of the letters "d" and "i". The word derives its name from the discoverer, Mario Fuenzalida, and the suffix "-ite," which is commonly used to describe minerals.
Fuenzalidaite is a term used in mineralogy to define a rare copper mineral. It is named after Miguel Fuenzalida, a prominent Chilean geologist who worked extensively on the mineralogy of Chile. Fuenzalidaite is classified as a complex copper molybdate hydroxide mineral that is commonly found in the oxidized zones of hydrothermal copper deposits.
This mineral usually occurs as small, tabular or prismatic crystals that can display a vitreous to adamantine luster. Its color ranges from pale blue, green, or yellow to colorless. Fuenzalidaite has a brittle tenacity and can exhibit perfect cleavage in one direction.
Chemically, fuenzalidaite contains copper, molybdenum, oxygen, and hydrogen, with the chemical formula Cu2Mo6+O4(OH)6·3H2O. It belongs to the monoclinic crystal system and is typically found as aggregates or crusts on a host rock. Fuenzalidaite has a relatively high density and is a non-fluorescent mineral.
Although fuenzalidaite is a rare mineral, it has been found in several locations worldwide, including Chile, Argentina, Kazakhstan, and the United States. It often forms as a secondary mineral due to oxidation processes in copper-rich environments. Its unique crystal structure and chemical composition make fuenzalidaite of interest to mineral collectors, researchers, and geologists studying copper mineralization and ore deposits.
The word "fuenzalidaite" is a mineral named after Dr. Carlos M. Fuenzalida, a geologist and mineralogist from Chile. The mineral was discovered in the Pampa de Pabellón volcanic complex in Chile. The suffix "-ite" is commonly used in mineral names to indicate that it is a mineral or mineral species.
