1961J. M. Sweet in Mineral. Mag. XXXII. 750 It is thought that this mineral is sufficiently distinctive to deserve a name of its own and that tacharanite..from the Gaelic tacharan (a changeling) would be suitable, both from the nature of its behaviour and the wealth of folklore associated with the island [sc. Skye] in which it occurs. 1975Ibid. XL. 113 Tacharanite has been reexamined... The composition approximates to Ca12Al2Si18O69H36. 1978Ibid. XLII. 383/1 Tacharanite in fractures in metagabbroic rocks filled by zeolitic assemblages has been found in the Gruppo di Voltri, Ligurian Alps. |
