(a) and (c) Optical micrographs of ADH crystals grown from solution in a diamond anvil cell, reproduced from Figs. 2(b) and 5 of Boone & Nicol (1991) with the permission of the Lunar and Planetary Institute. (b) and (d) Model crystals, drawn using the program WinXMorph (Kaminsky, 2005) using the orthorhombic unit-cell indexing of ADH IV reported in Table S1; these have been oriented to best match the crystals in (a) and (c). |
