About SarrabusiteHide

Formula:
Pb5CuCl4(SeO3)4
Colour:
Lemon yellow
Lustre:
Vitreous
Specific Gravity:
6.011 (Calculated)
Crystal System:
Monoclinic
Name:
For its occurrence in the Sarrabus region, Sardinia, Italy.
The mineral sarrabusite was approved by the IMA-CNMMN in 1997 (IMA1997-046a) and mentioned without a complete description in the paper on the new mineral orlandite (Campostrini et al., 1999). Later, it was indicated as UM 1999-29-SeO:ClCuHPb. The name sarrabusite appeared for the first time in 2011 on the IMA List of Minerals and the structure was solved by Gemmi et al. (2012).
