tienshanite Tienshanite, named for the Tian Shan Range in Mongolia, is a rare borosilicate mineral, though rock-forming in some parts of its original locality at the Dara-i-Pioz Glacier in Tajikistan.〔(Mindat.org - Tienshanite )〕〔(Webmineral.com - Tienshanite )〕〔(Handbook of Mineralogy - Tienshanite )〕 Its formula is extremely complex: KNa3(Na,K,[])6(Ca,Y,RE)2Ba6(Mn2+,Fe2+,Zn,Ti)6(Ti,Nb)6Si36B12O114[O5.5(OH,F)3.5]F2.〔Cooper M.
