| 中文摘要:文章阐述了西华山黑钨矿_石英脉与普通热液石英脉的不同之处；分析了前人所获压力值较低（30～70 MPa）的主要原因；利用黑钨矿_石英脉绿柱石中两相气液包裹体和不混溶硅酸盐熔融包裹体的有关资料及相关相图，求得西华山脉钨矿床的形成压力为200 MPa。根据西华山脉钨矿床产出的地质特征以及岩石学、矿物学、稳定同位素和流体包裹体地球化学等证据论证了这一压力的合理性。 |

| Abstract:The authors deal in this paper with the differences between wolframite_quartz veins in Xihuashan and common hydrothermal quartz veins，and analyze the main reasons for the relatively low formation pressure data (30～70 MPa) of the wolframite_quartz veins obtained by other geologists. The mineralization pressure of the Xihuashan wolframite_quartz veins is determined to be 200 MPa by using relevant data and phase diagram of gas_fluid inclusions and antipathetic melting silicate inclusions in beryl. Based on a study of geological，petrological，mineralogical and geochemical characteristics of stable isotopes and fluid inclusions，this paper demonstrates the rationality of the pressure determined by the authors. |
