Experimental constraints on amphibole stability in primitive alkaline and calc-alkaline magmas [PDF]
, 2017 Equilibrium crystallization experiments were carried out on two primitive basaltic rocks (APR16: Na2O+K2O=4.40 wt%; CM42: Na2O+K2O=2.59 wt%) with the aim to investigate the amphibole stability in the differentiation processes at deep crustal level, of

Thermally induced behavior of the K-exchanged erionite. A further step in understanding the structural modifications of the erionite group upon heating [PDF]
, 2018 Fibrous erionite is a naturally occurring zeolite considered to be highly carcinogenic upon inhalation, even more than crocidolite. Since no iron is typically present in erionite, its toxicity has been attributed to ion-exchanged Fe participating in ...
