| 中文摘要: |
| 对胶东15个金矿床围岩蚀变带内30个云母类矿物的地质产状、空间分带、与矿化关系的地质调查基础上,着重对各类型金矿床蚀变带内云母类矿物进行了单矿物提纯、矿物化学定量分析、物理性质鉴定、X光衍射分析、差热分析、红外吸收光谱分析、晶格常数计算、形成条件等方面的系统研究,确定了蚀变岩带内有9种云母类矿物,5个矿物化学-多型系列,新鉴定出5种云母类矿物:绿鳞石(Celadonite)、铁绿鳞石(Ferian Celadonite)、铁铝绿鳞石(Ferian-Alumino Celadonite)、铝绿鳞石(Alumino Celadonite)和伊利石(Illite)。总结了云母类矿物各系列的演化特征。查明了金矿床各蚀变-矿化带内所出现的云母类矿物晕。指出各云母类矿物晕的找矿信息。 |
| 英文摘要: |
| Fifteen Au deposits were investigated and occurrences, zonation of 30 varieties of mica and their relation to Au mineralization are clearly made. 9 types and 5 mineral chemistry-polytypic series of mica varieties in altered wall rocks of the deposits are recognized according to chemical analysis, XRDA, DTA, infrared absorption analysis, lattice constant calculation. Five varieties are newly identified, such as celadonite, ferrian celadonite, ferrian-allumino celadonite, allumino-celadonite and illite. Evolutionary series of the varieties and their halo in alteration-mineralization zones are summarized and delineated and their ore-searching informations are put forth. |
