Name(s) in local language(s):
Kaxtorpiten ("Eckermannit-typlokaliten"), Norra Kärr nefelinsyenit, Gränna, Jönköpings kommun, Småland, Sverige
The laxtorpite body measures about 150 x 75 m, and is located SW of the Norra Kärr Farm. This being the largest of three kaxtorpite bodies in the Norra Kärr complex. This is found in the central part of the complex and is known for being the first recorded locality for eckermannite sensu lacto. This amphibole is now redefined by IMA in 2014 (IMA2013-136). Re-examination of the holotype material of the original sample analyzed by Törnebohm (1906) confirmed that they both are actually fluoro-leakeite.
NB: eckermannites sensu lacto are found in all three laxtorpite outcrops. Old specimens labelled as "eckermannite, Norra Kärr" does not neccessarily originate from this sublocality.
