Verona and Vicenza areas are well known for zeolites specimens, occurring in geodes and fractures of basaltic volcanic rocks of the Tertiary ages. Amongst these zeolites I have some nice pieces of harmotome and phillipsite.
P
hillipsite-harmotome series minerals are difficult to distuinguish

 

 

Harmotome
Group of rounded formations made of radiating prismatic XX. Minerals from the harmotome-phillipsite series are difficult to distinguish, but from this locality the orange mineral is always armotome; phillipsite is white

Harmotome
Combination of orange rhombic XX, about 0.5cm wide; harmotome is always twinned. This kind of specimen - from this locality - was also known with the old  name of "wellsite", discredited by IMA (International Mineralogical Association) in 1997: today is either barian philipsite-Ca or calcian harmotome. The piece cames from the basaltic occurrences along the route to monte Calvarina
