摘要
系统地研究湘桂粤赣地区主要类型锡矿床的包裹体特征,表明锡石主要形成于250～400℃范围,成矿流体以中低盐度为主,属Ca^(2+)-Na^+-F^-型的富CO_2流体.同时还指出包裹体在矿田和矿床范围内具有分带的特征,最后提出流体的沸腾和混合是锡多金属矿床的重要成矿作用.
A systematical investigation on the characteristics of inclusions in the major types of tin deposits in the area of Hunan, Guangxi, Guangdong and Jiangxi province has been made, indicating cassiterite being mainly formed in the temperature ranging from 250℃ to 400℃ , ore-forming fluids being intermediate-low salinity of CO2-rich Ca2+-Na+-F- type. The zonation feature of inclusions in the scope of orefield and ore deposits was also pointed out. It is suggested that the boiling and mixing of fluids are important metallization process for the formation of Sn-polymetallic deposits.
