英文摘要	The Himalayan mineral field includes over 50 quartz-vein type Sb-Au deposits, and placer Au deposits.The poorly documented Lagiong deposit is a typical example of quartz-vein type Sb-Au mineralisation in Tethys Himalayan sequence. The orebody are controlled by shallow north-dipping normal faults and north-south trending faults. Magmatic zircons extracted from muscovitic leucocratic granite from the southern part of the Laqiong mine area yield a Laser Ablation-Inductively Coupled Plasma-Mass Spectrometry U-Pb age of 14 +/- 1 Ma (n = 12, MSWD = 0.9) that is similar to the Ar-40/Ar-39 age of ca. 14 Ma from hydrothermal sericite in auriferous sulphide-quartz veins. The epsilon(Hf)(t) values for the magmatic zircon rims range from -5.4 to -1.9, corresponding to two-stage Hf model ages of 1403-1214 Ma. Quartz from the mineralised veins has delta O-18(H2O-SMOW) values varying from +4.97 to +9.59 parts per thousand and delta DH2O-SMOW values ranging from -119.7 to -108.1 parts per thousand. The delta C-13(V-PDB) values for calcite from the ore Stage III range from -6.9 to -5.3 parts per thousand, and calcite from Stage IV are -3.5 to -1.7 parts per thousand. The delta O-18(V-SMOW) values for calcite from Stage Blare +20.3 to +20.6 parts per thousand and for Stage IV are -63 to -4.9 parts per thousand. The stibnite and pyrite samples have Pb-208/ Pb-204 ratios of 38.158 to 39.02, Pb-20(7)/ Pb-204 ratios of 15.554 to 15.698, and Pb-206/Pb-204 ratios of 17.819 to 18.681, and bulk and in-situ delta S-34(V-CDT) values for stibnite, arsenopyrite and pyrite range from -1.1 to +2.3 parts per thousand The calcite from the orebodies are enriched in MREE and depleted in LREE and HREE. Fieldwork, petrological, and geochemical data collected during our study leads to the following salient findings: the mineralising fluid is a mix of magmatic and meteoric fluids: and the deposit is closely related to the emplacement of Miocene granites originating from a thickened continental crust.
