Fig. 5.11 Sample forms and holders for Mössbauer spectroscopy. a plastic sample holder (diameter
12 mm). b hole drilled in lead foil (hole diameter 1 mm). c powder mixed with glue and affixed
onto plastic sheet (sample diameter 4 mm). d single grain on plastic sheet (grain dimensions 900 ×
600 μm 2 ) (enlarged view shown in inset). e multiple grains formed into mosaic (sample diameter
7 mm). f glass shards in epoxy (disk dimensions 9 × 6 mm 2 ). g capsule from high-pressure
experiment in epoxy (capsule dimensions 1400 × 900 μm 2 ). h single crystal clinopyroxene cut
into a cube (700 × 700 × 700 μm 3 ). i oriented garnet single crystal cut and polished into a slice
and glued onto an epoxy disk (sample dimensions 1.5 mm diameter × 150 μm thick) (garnet data
reported in [36]). j suboceanic lava thick section (3.5 × 2 × 0.5 mm 3 ) (provided by N. Hirano).
k metasomatised eclogite thick section (2 × 2 × 0.5 mm 3 ). l inclusions within intact diamond
(diamond dimensions 3 × 3 × 3 mm 3 ) (adapted from [23]). m inclusions exposed by polishing
diamond slice (diamond dimensions 2.2 × 1.8 × 0.5 mm 3 ) (data reported in [39]). n single crystal
(centre) inside diamond anvil cell with ruby chip for pressure calibration (upper left) (gasket hole
diameter 100 μm). o polycrystals inside a diamond anvil cell (gasket hole diameter 120 μm). The
latter two images are adapted from [40]
