| 中文摘要: |
| 早前寒武纪变质岩系是辽宁地区古老变质岩系的重要组成部分,变质程度高于绿片岩相,局部可达麻粒岩相。通过研究辽宁早前寒武纪变质岩系元素地球化学特征,计算了辽宁地区早前寒武纪变质岩系元素原始浓集系数,建立了不同构造单元和地层单元元素的原始浓集模型。 |
| 英文摘要: |
| The Early Precambrian rocks are the important constituent of old metamorphic terrains in Liaoning province,mainly in metamorphic facies higher than greenschist and locally reaching granulite facies.Based on the study of element geochemical characteristics and the initial concentration coeficient calculated for Early Precambrian rock seguence in Liaoning province the element concentration model for varied tectonic units and stratigraphic units is establised. |
