1.6.13 Pressed pellet

  • Child of: analyticalpreparation solidmaterialsample
  • a sample prepared by grinding a parent sample to a fine powder, mixing it with a binder, and pressing the mixture into a die at a pressure of between 15 and 35 tons to produce a solid disc for subsequent analysis, typically by X-Ray fluorescence.

1.6.19 Microtome slice

  • Child of: solidmaterialsample
  • Typically from TEM analysis. Slices are commonly deposited in a grid contain with multiple slices and the grid will be given a single sample name, not the individual slices within it. The provenance of the slice from paticle to mounted specimen to slice should be carefully documented
  • A very thin slice cut from a mounted specimen using a mocrotome or ultramicrotome.

1.6.21 Particle

  • Child of: solidmaterialsample
  • Can also used for small peices broken from a ‘Rock hand sample’. OSIRIS-Rex definition specifies ‘competent individual geologic sample of any size’. ‘Competent’ interpreted to be equivalent to ‘solid’, or ‘consolidated’. The definition here is broader in that it includes materials of any origin, but narrower in that it is restricted to small objects.
  • A small individual solid object that is not one of the other sample types.
