- W1569213147 abstract "通过矿床地质地球化学、煤岩学、有机地球化学及成矿模拟实验的研究,首次阐明临沧盆地大寨超大型煤中锗(铀)的有机成矿机理:初始锗来源于赋锗的花岗岩风化产物;在泥炭化阶段通过微生物对陆生高等植物降解和改造,经有机质吸附和生成锗络合物等环节构成富锗泥炭层.当富锗泥炭层形成褐煤时,未成熟有机质从含锗的粒间孔隙水中富集锗形成褐煤锗矿层;在表生氧化阶段中,褐煤锗矿层中锗被含氧地下水淋滤、迁移、叠加再造形成富大锗矿体.为进一步探讨锗矿的有机成矿机理进行了包括浸出、吸附、络合的锗矿预富集,以及锗重新迁移和聚集实验,来表述和证明上述有机成矿机理." @default.
