＜正＞Rutile　grains　often　occur　in　different　types　of　gold　deposits,　and　their　U-Pb　ages　have　been　widely　used　to　determine　the　formation　time　of　gold　mineralization.　However,　the　origin　of　rutile　grains　in　the　gold　deposits　remains　controversial.　In　this　paper,　laser　ablation-inductively　coupled　plasma-mass　spectrometry　(LA-ICP-MS)　analyses　of　U-Pb　ages　and　trace　elements　on　rutile　grains　were　applied　to　investigate　the　metamorphic　and　hydrothermal　processes　of　the　Baiyun　gold　deposit　(70　t　Au,　average　grade:　3g/t)　in　the　Liaodong　Peninsula,　northeastern　part　of　North　China　craton　(NCC).
