在平桂地区含锡夕卡岩锡的赋存状态研究过程中,发现在不同成矿阶段所形成的矿石里锡的赋存状态不同;找出了形成不同工艺类型矿石的地质成因,进而对锡的地球化学行为进行了初步探讨.根据不同类型矿石(岩石)中锡的赋存状态和锡石的产出特征,初步认为锡元素在夕卡岩早期(450—500℃),主要呈类质同象分散在钙铁榴石中;在夕卡岩晚期(300—450℃)
In the study of the occurrence state of tin-containing skarn tin in Pinggu area, it was found that the occurrence state of tin in the ore formed in different mineralization stages was different; the geological origin of ore forming different process types was found out, Tin geochemical behavior of a preliminary study.According to the occurrence of tin in different types of ore (rock) and cassiterite output characteristics, we initially believe that the tin element in the early skarn (450-500 ℃), the main was class The mass is dispersed in the dacite; in the late skarn (300-450 ° C)
