On the new mineral theophrastite, a nickel hydroxide, from Unst, Shetland, Scotland
抄録
<jats:title>Abstract</jats:title><jats:p>The new mineral theophrastite, Ni(OH)<jats:sub>2</jats:sub>, from Unst, is Mg-bearing and occurs associated with a very poorly crystalline Ni-containing mixed hydroxide of the pyroaurite type and/or zaratite on chromitite. X-ray powder diffraction data show a shift in <jats:italic>d</jats:italic> spacing toward brucite compared with pure Ni(OH)<jats:sub>2</jats:sub>. Infrared, thermal, chemical, optical, and physical data are presented together with indexed powder data for fifteen lines ranging from <jats:italic>d</jats:italic> 4.66Å to 0.90Å. The solid-solution series brucite-theophrastite is briefly discussed.</jats:p>
