Siderite ("mesitine"
?)
Group of delicate white XX up to 2.1cm long. The
geode with this mineral seems to be exausted, after the last finding of 2005.
Some one classify this piece as mesitine but bibliografy reports
a different story; mesitine is a variety of ferroan magnesite, like the
breunnerite n.36 you can see in the other section devoted to Italian
minerals
(I maintain some doubts about this piece...)
