secondo me dovresti fare una foto con inquadratura più ampia, per vedere i campioni per intero.
Ciao

Perchè viste cosi, la prima sembra quella che trovavano nelle miniere del Sarrabus.
la seconda ricorda le cristallizzazione che si trovano sia nella miniera nella zona di Capoterra, sia nella zona di Iglesias (esempio miniera San Giovanni).

Per quanto riguarda il primo campione non saprei che dire, per il secondo invece escluderei a priori San Leone c/o Capoterra-Ca- .Come dice Giovanni ci sono somiglianze , ma diversa è la matrice e ci sono anche sostanziali differenze nella forma del cristallo.
Alcune foto di vecchi esemplari provenienti da tale località sono presenti sul sito AGMT in un apposito album di campioni sardi.
