  "term": "Twitch",
  "field": "Industrial and trades",
  "definition": "A sudden narrowing or pinching out of a coal seam or mineral vein, creating a localized area where the deposit is thin or absent. This geological irregularity complicates mining operations by interrupting the continuity of the resource and requiring adjustments to extraction plans. A twitch is distinct from a fault, as it involves a change in the seam's deposition rather than a displacement of the rock strata.",
