Important natural geological analogues are volcanic glass and meteoric glass(anal-ogues of solidified mass), clay minerals (natural analogues of backfill material), iron meteorite and copper deposits (natural analogues of waste containers), natural nuclear reactors, uranium deposits, iron deposits containing Th and REE and contact zones between igneous rocks and other rocks (natural geochemical analogues of HLW repository).

目前已有的地质类比研究对象主要有火山玻璃，陨石玻璃，粘土矿物，铁陨石，铜矿床，铀矿床，含含Th和REE的铁矿床，天然核反应堆和火成岩接触带等。
