| 中文摘要: |
| 贵州玄武岩属稳定地块裂陷阶段—二叠纪非造山期产物，以海相喷溢和陆相喷溢为主，通过取样分析，得出贵州玄武岩的地球化学特征，化学成分以SiO2为主，化学成分因取样区域不同含量也不相同，大部分样品进行拉丝实验成功。稀土元素分析数据表明取样玄武岩属轻稀土富集型，微量元素实验显示相容元素Cr、Co、Ni和不相容元素V、Mn、Ti的异常以及Cu元素特高值出现的原因。通过样品中的成矿元素含量富集分析成矿作用，并为下一步寻找矿产提供一种手段。 |
| 英文摘要: |
| The basalt in Guizhou is the produc of craton chasmic stage-Permian orogenic period, with Marine eruption and continental eruption is given priority to， through the sample analysis, it is concluded that the geochemical characteristics of basalt in guizhou， chemical composition is given priority to with SiO2, chemical composition because of different levels have different sampling area, most of the samples drawing experiment is successful.The analysis data of rare earth elements indicate that the basalt of the sample belongs to the enrichment type of light rare earth, and the experiment of trace elements shows the abnormality of compatible elements Cr, Co, Ni and incompatible elements V, Mn and Ti, as well as the reason for the occurrence of extra high value of Cu.The metallogenic process is analyzed by enrichment of metallogenic elements in the samples, and it provides a means to search for mineral resources in the next step. |
