Baccu Locci is the type locality for the selenites orlandite and sarrabusite. 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).

This geological map and associated information on rock units at or nearby to the coordinates given for this locality is based on relatively small scale geological maps provided by various national Geological Surveys. This does not necessarily represent the complete geology at this locality but it gives a background for the region in which it is found.

541 - 1000 Ma
|Neoproterozoic intrusive and metamorphic terranes|
Age: Neoproterozoic (541 - 1000 Ma)
Comments: Mixtures of metamorphic and intrusive or plutonic rocks, tracts known as crystalline, migmatitic terranes, moderately to highly metamorphosed rocks of unknown origin with or without intrusions. This classification is inherently prone to variable interpretation, as other compilers might distinguish some packages by their metamorphic or gneissic protoliths, and the associated age ranges may be more variable.
Lithology: Intrusive and metamorphic terranes
