07083660015539873827872.jpg
Ulf B. Andersson
Formula:
(Ce15Ca)Σ16Mg2(SiO4)10(SiO3OH)(OH,F)5Cl3
Colour:
Pinkish
Hardness:
5 - 6
Specific Gravity:
4.97 (Calculated)
Crystal System:
Monoclinic
Name:
The name honours Ulf B. Andersson (b. 1960), Swedish geologist and petrologist with the mining company Luossavaara-Kiirunavaara Aktiebolag (LKAB), who has contributed significantly to the understanding of the genesis of REE deposits of Bastnäs type.
New structure type. Unique combination of elements among the approved mineral species - the only known natural Ce-Ca-Mg silicate chloride (although somewhat comparable to 'UM2007-39-SiO:ClFHMgREE').

In the nearby Nya Bastnäs ore field, microscopic mineral grains found in contact with cerite-(Ce) (Holtstam & Andersson, 2007) may represent an unnamed Fe analogue of ulfanderssonite-(Ce).
