| 1952 Sakurai & Hayashi in Sci. Rep. Yokohama Nat. Univ. Section II. i. 77 We can not identify this mineral with the other zeolites, and we may consider this to be a new zeolite. We wish to [call] it ‘Yugawaralite’ after its locality. 1969 Acta Cryst. B. XXV. 1190/1 It is difficult to place yugawaralite in any of the seven recognized groups of zeolites, although it shows certain similarities to both mordenite and heulandite. 1978 Mineral. Rec. IX. 296/1 Yugawaralite, a relatively rare calcium zeolite,..has been found in specimens mined from the Khandivali quarry near Bombay, India. |
