1904Lindgren & Hillebrand in Amer. Jrnl. Sci. CLXVIII. 457 Considering that the mineral is not a mixture, but optically well individualized, we have..thought it best to designate it by the name morencite, derived from the locality in which it was found. 1928Ibid. CCVIII. 12 There is no good reason for separating müllerite, morencite, and hoeferite from nontronite on account of their lower water content. 1935Amer. Mineralogist XX. 475 Nontronites including morencite, pinguite, faratsihite, stilpnochloran and chloropal are like montmorillonite in structure. |
