  "term": "Granite",
  "field": "Oil and gas",
  "definition": "A common type of felsic intrusive igneous rock, characterized by its coarse-grained texture and composition primarily of quartz, feldspar, and mica. While not typically a reservoir rock itself due to its low porosity and permeability, granite can form the basement beneath sedimentary basins. It can also be a source of heat for hydrocarbon maturation in overlying sediments.",
