1836 T. Thomson Outl. Mineral. I. 351 The third species [of harmotome], to which I have given the name of morvenite.

1869 Philos. Trans. 1868 (Royal Soc.) 158 565 It is now some years since I showed that simple crystals of Harmotome did not exist, and that those of Strontian in Scotland (Morvenite)..presented, in fact, a twinning formed by the interpenetration of two principal individuals.

1883 Encycl. Brit. XVI. 423/1 Harmotome... Strontian, transparent (Morvenite, fig. 572) and opaque.

1967 Mineral. Mag. 36 446 In addition to the simple morvenite twinning, complex cruciform twinning of the Marburg type is common.

1997 R. V. Gaines et al. Dana's Syst. Mineral. (ed. 8) 1665 Harmotome appears to nucleate as twins. The major twin types are: Morvenite: fourling twin present in all crystals [etc.].
