| 中文摘要: |
| 本文在赣东北地区的前震旦系地层划分对比及岩性、岩相与岩石化学、微量元素、稀土原素综合研究的基础上,对不同地体、不同层位、不同岩性中金的分布规律及富集趋势进行了研究,指出了岛弧火山浊积岩含金建造的重要性. |
| 英文摘要: |
| In Northeastern Jiangxi, the combination zone of Yangtze palaeo-plate and Cathaysian is a important minerogenetic prospect province of gold.In the presinian metamorphic strata, the tendency of gold enriching initially has been closely related to geotectonic positions、sedimentary facies, stratum age, characteristics of lithological and petrochemistry, distributions of trace elaments, associations of rare earth elements.On the basis of comprehensive studies, The authors has determined ten rules of gold enriching and emphasized the importance of gold-bearing property of pyroclastic flysch from island arc (as well as spilite-keratophyre formation) |
