Overview

Senaite is a rare mineral with the chemical formula Pb(Mn,Y,U)(Fe,Zn)2(Ti,Fe,Cr,V)18(O,OH)38. It is a complex oxide mineral that belongs to the Strunz classification 4.CC.40. Senaite crystallizes in the monoclinic crystal system and is characterized by its dark coloration, typically black to dark brown. It exhibits a submetallic to dull luster and is relatively dense, with a hardness that is not precisely defined due to its rarity. Senaite is notable for its high content of lead, titanium, and various transition metals, making it a member of the oxide mineral group.

Etymology

Senaite is named after Joaquim Cândido da Costa Sena, in recognition of his contributions to mineralogy. The mineral was not officially approved by the IMA but is considered grandfathered.

How to recognize it

Senaite can be identified by its dark color and submetallic to dull luster. Its hardness is not well documented, but it is likely to be low to moderate on the Mohs scale. The mineral has a high density, which can be a distinguishing feature. Senaite does not have a well-defined streak color due to its rarity and dark coloration. It is easily confused with other dark, dense oxide minerals, but its complex chemical composition and monoclinic crystal system help in differentiation.

Trivia

Senaite is notable for its complex chemical formula, which includes a wide range of elements such as lead, uranium, and titanium. It is one of the few minerals that contain both yttrium and uranium in its structure. Additionally, the mineral's name honors Joaquim Cândido da Costa Sena, a significant figure in the field of mineralogy.
