Abstract

Harmotome and chabazite from Do’ le Pale, Fassa Valley (Trento, Italy) - This work will provide amorphological and crystal chemical description of harmotome and chabazite from Do’ le Pale, Fassa Valley,Trentino, Northern Italy. The chemical formula and the monoclinic unit cell parameters of cross twinned harmotomecrystals are (Na0.85 K0.13 Ca0.14 Sr0.01 Ba1.84)(Fe0.02 Al5.01Si11.00) O32·12.73 H20 and am= 9.902(4), bm= 14.145(5), cm=8.765(3) (Å), β(°)= 124.56(2), Vm= 1000.6(6) (Å)3, respectively. Results of the Do’ le Pale harmotome will be comparedto those obtained for harmotome from Iskra (Bulgaria) and from Selva di Trissino (Vicenza, Northern Italy).The latter is the only Italian sample with a full characterization in the literature. The chemical formula and the hexagonalunit cell parameters of chabazite, which often presents phacolitic habit, are (Na0.03 K0.13Ca1.57 Sr0.09Ba0.05)(Al3.51Si8.48)O24·12.94H20 and ahex.= 13.802(2), chex.= 15.009(3), Vhex.= 2476.1(5) (Å)3, respectively. Crystal chemical featuresof chabazite from Nova Scotia (Canada) and from Madzv arovo (Bulgaria) will be used for the comparison withthe accomplished results.
