Radial sectioning

  "id": "MLC-T-CHM-013466",
  "term": "Radial sectioning",
  "field": "Chemistry",
  "definition": "A sample preparation method for depth analysis in which the surface is polished with a rotating cylinder to cut a curved crater, exposing compositional changes below the original surface. The depth of each layer is related to its lateral position on the polished surface, so a small-probe surface analysis technique can scan across the crater to build a depth profile. Ball cratering is the related method that uses a sphere in place of a cylinder.",
