运用高分辨率飞行时间型二次离子质谱仪 (TOF -SIMS) ,研究了内蒙古乌达矿区高硫煤 9煤层中黄铁矿化的杆状菌落的谱图特征、无机和有机碎片离子的组成、Fe+以及共伴生无机元素二次离子像特征 ,讨论了菌落在黄铁矿形成过程中的作用 .除检测到Fe+(5 4Fe+,5 6 Fe+,5 7Fe+)外 ,与黄铁矿化杆状菌落伴生的无机元素还有2 7Al+,Si+(2 8Si+,2 9Si+,30 Si+) ,40 Ca+,Cu+(6 3Cu+,6 5 Cu+) ,Zn+(6 4Zn+,6 6 Zn+,6 7Zn+,6 8Zn+)和Ni+(5 8Ni+,6 0 Ni+,6 2 Ni+)等 ,表明菌落在生物成因黄铁矿的形成过程中 ,在改变介质条件 ,及迁移、活化和富集Cu ,Zn等金属元素方面做出了贡献 .
Using high-resolution TOF-TOF-SIMS, the spectral characteristics of pyrite mineralized rod-shaped colonies in high-sulfur coal seam 9 in Wuda, Inner Mongolia were studied. The composition of inorganic and organic fragment ions , Fe + as well as the secondary ion image of co-associated inorganic elements, the role of colonies in pyrite formation was discussed.In addition to the detection of Fe + (5 4Fe +, 5 6 Fe +, 5 7Fe +), The inorganic elements associated with colony are also 2 7 Al +, Si + (2 8Si +, 29Si +, 30Si +), 40Ca +, Cu + (6Cu +, 6 5Cu +), Zn + (6 4Zn + 6 6Zn +, 6 7Zn +, 6 8Zn + And Ni + (5 8Ni +, 6 0Ni +, 6 2Ni +) and so on, indicating that the colony in the formation of biogenic pyrite in the medium conditions, and migration, activation and enrichment of Cu, Zn and other metal elements made Contribute.
