摘要:

上宫金矿床位于熊耳山金矿田北部。通过对上宫金矿床区域地质背景、矿床地质特征、成矿流体特征进行研究,认为成矿流体演化可分为4个阶段。矿石包裹体以气液两相包裹体为主,常见气液比5 %~10 %,但从5 %~30 %均有产出;最有利的成矿温度为200 ℃~300 ℃;盐度主要集中于5 %~10 %,平均值为8.9 %,成矿流体为中高盐度流体;成矿压力为80~93 MPa;成矿流体主要属于NaCl-CO、CO2-H2O的含卤素和碱质水溶液体系,随着温度的降低,由成矿阶段到成矿后阶段,成矿溶液发生了由弱酸性向弱碱性的转变。研究成果对区域内类似金矿床成矿流体特征研究具有一定借鉴意义。

Abstract:


Shanggong Gold Deposit is located in the north of Xiongershan Gold Field.Based on the study of the regional geological background,geological characteristics,and characteristics of ore-forming fluids of Shanggong Gold Deposit,it is considered that the evolution of ore-forming fluids of Shanggong Gold Deposit has 4 stages.The ore inclusions are dominated by gas-liquid two-phase inclusions,which commonly occur with the gas-liquid ratio of 5 %-10 % and possibly occur with 5 %-30 %;the most favorable metallogenic temperature is 200 -300 ;the fluid is with a medium-high salinity,mainly between 5 % and 10 %,8.9 % on average;the ore-forming pressure is 80-93 MPa;the ore-forming fluid mainly belongs to the NaCl-CO,CO2-H2O system containing halogen and alkaline water solution.When the temperature decreases and the ore-forming stage proceeds to the post-mineralization stage,the ore-forming solution changes from weak acidity to weak alkalinity.The results can be used as a reference to study the characteristics of ore-forming fluids in similar gold deposits in the region.
