Notes: Mae'r diffiniad yn cyfeirio yn benodol at ystyr y term hwn yn y gyfundrefn gyfreithiol ar gyfer cynllunio. Mae ystyr fwy caeth i mineral/mwyn mewn cyd-destunau gwyddonol a chyffredinol. Bryd hynny, bydd y termau yn y ddwy iaith fel arfer yn golygu sylwedd solet anorganig sy'n ffurfio'n naturiol, gyda chyfansoddiad cemegol penodol a strwythur a nodweddion ffisegol nodweddiadol. Y gwahaniaeth ymarferol rhwng y diffiniad cyfreithiol a'r diffiniad gwyddonol yw bod y diffiniad cyfreithiol yn gallu cynnwys glo, mawn a chreigiau megis llechi, tra bod y diffiniad gwyddonol yn eithrio sylwedddau o'r fath.
