Naozhi gold deposit located in the western sector of Yanbian—Dongning gold metallogenic belt��is a quartz vein type deposit occurred in Hercynian granodiorite�� The analysis results of geological characteristics and the fluid inclusions in auriferous quratz veins show that the main types of fluid inclusions developed in auriferous quartz vein are gas-liquid two-phase��and a little daughter mineral-bearing three-phase as well as vapor phase fluid inclusions�� The homogenization temperature of gas-liquid two-phase fluid inclusions is 283. 5 �� �� 375. 9 �棬with salintity 3. 4 �� 8. 13 wt%NaCl; the homogenization temperature of vapor phase fluid inclusions is 416. 5 �� �� 431. 6 ��; and the homogenization temperature of NaCl daughter mineral-bearing three-phase fluid inclusions is 303. 9 �� �� 393. 2 �棬with salinity 38. 21 �� 45. 3 wt%NaCl�� The oxygen and hydrogen isotopes of fluid inclusions indicate that the ore-forming solutions mainly derived from magmatic fluids which mixed with a small amount of meteoric water�� The gold deposit belongs to medium temperature magmatic hydrothermal type in origin��
