The　Hebaoshan　gold　deposit　(41.5　t　Au　@　3.5　g/t)　is　located　in　the　southeastern　region　of　the　South　China　Block,　central　part　of　the　Wuyishan　metallogenic　belt.　The　ore-hosting　rocks　in　this　area　are　predominantly　Precambrian　metasedimentary　rocks　and　Caledonian　granitic　rocks.　Two　hydrothermal　mineralization　stages　can　be　distinguished:　a　quartz-sericite-pyrite-native　gold　(stage　I)　and　a　chlorite-quartz-sericite-chalcopyrite-electrum　(stage　II),　with　hydrothermal　monazite　and　rutile　are　firstly　identified　in　separate　stages.　The　complex　geological　history　of　the　region　has　resulted　in　ongoing　debates　regarding　the　age　of　gold　mineralization　and　the　genesis　of　the　major　gold　deposits　in　this　area.　In　order　to　precisely　constrain　the　mineralization　age　of　the　deposit　and　further　establish　a　genetic　model　for　the　ore　deposit,　LA-ICP-MS　U-Pb　dating　and　trace　element　analysis　on　accessory　minerals　were　conducted.　Based　on　the　textures　mineral　assemblages,　and　geochemical　features　of　the　accessory　minerals,　magmatic　apatite,　hydrothermal　rutile,　and　both　magmatic　and　hydrothermal　monazite　were　identified.　The　U-Pb　ages　of　magmatic　apatite　and　monazite　are　determined　to　be　445.3　±　15.80,　441.3　±　15.10　Ma　and　446.57　±　1.03　Ma,　respectively,　suggesting　that　these　ages　represent　the　emplacement　ages　of　the　Caledonian　intrusive　rocks.　The　ages　of　hydrothermal　monazite　and　hydrothermal　rutile　are　determined　to　be　238.46　±　2.01　Ma　(single-mineral　analysis),　238.46　±　2.01　Ma　(in-suit　analysis)　and　179.54　±　7.28　Ma,　respectively,　suggesting　that　represent　two　mineralization　events　during　the　Late　Triassic　to　early　Jurassic　in　the　Hebaoshan　area.　These　data　provide　new　constraints　on　the　mineralization　process　in　the　Hebaoshan　deposit　and　excludes　the　link　between　gold　mineralization　and　the　intrusion　of　the　Caledonian　granites.　Regionally,　It　is　speculated　that　the　two　mineralization　events　at　Hebaoshan　are　respectively　associated　with　intracontinental　orogenic　movements　between　the　Yangtze　Block　and　Cathaysia　Block,　the　flat-slab　subduction　of　the　Paleo-Pacific　Plate　(stage　I),　and　the　subsequent　extensional　tectonics　related　to　the　collision　between　the　Yangtze　Block　and　Cathaysia　Block　(stage　II).　Our　study　indicates　that　the　timing　of　multiple　episodic　mineralization　can　be　constrained　by　analysis　of　accessory　minerals,　which　provides　a　geological　basis　for　better　genetic　model　for　the　deposit　and　provide　geological　evidence　for　unraveling　the　relationships　between　magmatic　activities　and　mineralization　events　in　the　region.　©　2024
