... formational environments. Although inclusions, such as baddeleyite (ZrO 2 ) and srilankite ([Ti,Zr]O 2 ), as well as associated painite (CaZrAl 9 O 15 [BO 3 ]), indicate skarn-related paragenesis of some samples, no signatures of B or Zr enrichment were found. Rather high levels of Si (300+ ppm) are found...
