...G. Donald Eberlein; R. C. Erd; Florence Weber; L. B. Beatty Abstract Yugawaralite (CaAl 2 Si 6 O 16 ·4H 2 O), a relatively rare calcium zeolite, was found in a new locality near Chena Hot Springs, east-central Alaska in a geologic setting that diffesrs from that described for occurrences in Japan...

.... Sakurai and Hayashi (1952) reported that the 2Vγ value ranges from 56 to 89° in a specimen from Yugawara, Japan (the type locality). However, Eberlein et al . (1971) suggested that the 2Vα value varies from 48 to 72° in yugawaralite from the Chena hot spring area, Alaska. Also, the 2Vα value varies...
