【摘要】 邢家山矿床是胶东地区发现的大型矽卡岩型钼多金属矿床。通过野外调研,将成矿过程划分为四个阶段:早矽卡岩阶段、晚矽卡岩阶段、石英硫化物阶段和石英-碳酸盐阶段。对不同阶段流体包裹体研究表明,存在液体包裹体（L）、气体包裹体（V）和含子矿物包裹体（S）三类。激光拉曼探针显示流体的气体分类型为H₂O-H₂S,早和晚矽卡岩阶段均一温度集中在375～450℃,盐度存在14%～15%NaCleqv和大于30%NaCleqv两个端元;石英-硫化物阶段均一温度集中在260～340℃,盐度存在8%～12%NaCleqv和大于50%NaCleqv两个端元;石英-碳酸盐阶段流体包裹体均一温度集中在170～200℃,盐度小于10%NaCleqv。该矿床成矿流体具有高温高盐度的特征,且富含H₂S等还原性气体,从矽卡岩阶段到碳酸盐阶段成矿温度和盐度总体有降低的趋势。邢家山钼矿δ¹⁸ O_H2O值为0.04‰～8.18‰,δ¹³ C_V-PDB值为-3. 35‰～-0.73‰,δ¹⁸ O_V-SMOW值为5. 93‰～8. 42‰,δ³⁴S值为6.5～10. 8‰。邢家山矿床成矿流体主要来源于岩浆,后期有大气降水的加入,流体沸腾是成矿的主要机制。更多还原

【Abstract】 The Xingjiashan Mo deposit is currently a large skarn deposit in the Jiaodong metallogenic province. The hydrothermal activities of mineralization can be divided into four stages : early skarn stage（Ⅰ）,late skarn stage（Ⅱ）, quartz-sulfide mineral stage（Ⅲ） and quartz-carbonate stage（Ⅳ）. The characteristics of the fluid inclusions show that the inclusions can be divided into three types : liquid-rich inclusions（L）,vapor-rich inclusions（Ⅴ） and daughter mineral-rich inclusions（S）. The results of Roman spectra study show that the volatile phases have H₂ S. In the early and late skarn stages, the homogenization temperatures peak value range from 375℃ to 450℃,and the salinities have two ranges 14% ～15% NaCleqv and >30% NaCleqv. In quartz-sulfide mineral stage,the homogenization temperatures peak value range from 260℃ to 340℃,and the salinities have two ranges 8% ～10% NaCleqv and>50% NaCleqv. In quartz-carbonate mineral stage,the homogenization temperatures peak value range from 170℃ to 200℃, and the salinities ranges 8% ～10% NaCleqv and >50% NaCleqv. The values of δ¹⁸ O_{H2 O},δ¹³ C_V-PDB,δ¹⁸O_V-SMOW and δ³⁴S are 0.04‰～8. 18‰,-3. 35‰～-0.73‰,5. 93‰～8.42‰ and 6. 5‰～10. 8‰.These results indicate that the ore-bearing fluid in the early stage is characterized by high temperature and high salinity. The ore-forming fluids are mainly derived from magma. Magma water is major ore-forming fluid, with minor meteoric water in the late stage. Fluid boiling may be the mechanism of large-scale metallogenic precipitation.更多还原
