[ad. G. maskelynit (G. Tschermak 1872, in Sitzungsber. d. K. Akad. d. Wissensch. (Math.-Nat. Classe) LXV. 131), f. the name of Nevil Story-Maskelyne (1823-1911), English mineralogist): see -ite1.]
A colourless aluminosilicate of calcium and sodium which has a composition near to that of andesine and is found in some kinds of meteorite.
1875E. S. Dana in J. D. Dana Syst. Min. (ed. 5) App. ii. 37 Maskelynite. 1921Bull. Geol. Soc. Amer. XXXII. 402 The name maskelynite..was first given by Tschermak to an isotropic constituent of the habit and composition of a labradorite feldspar occurring in the stone of Shergotty. The name has since been extended to cover a colorless interstitial substance, sometimes quite isotropic and sometimes faintly doubly refracting, of like appearance and habit, and a common if not universal constituent of the chondritic meteorites. 1971Physics Bull. Oct. 578/2 It appears that intense shock disorders the lattice to produce the isotropic mineral maskelynite. |
