| 中文摘要: |
| 黔东偏碱性超基性岩以富含金云母或钛黑云母为显著特征。分析认为，扬子地台基底固结程度低、盖层厚度大、变形变质浅，含水量大，地台盖层及基底富含的建造水，应大大地参与了偏碱性超基性岩在浅表层次侵位结晶过程中云母的形成，从而导致贵州黔东偏碱性超基性岩云母含量普遍偏高。 |
| 英文摘要: |
| The alkalescent ultrabasic rock in east Guizhou has a feature that it is rich of phlogopite or titanbiotiteIt’s thought the consolidation degree of Yangzte platform base is low，the over strata thickness is big，the deformation and metamorphism is small，the water content is abundant，the formation water of platform over strata and base should participate in the mica formation of alkalescent ultrabasic rock shallow emplacement crystallization，so it cause the high mica of alkalescent ultrabasic rock in east Guizhou |
