| 摘 要： | 二叠系白云岩与白云质灰岩、灰岩具有渐变过渡关系。白云岩中斑马状构造发育。白云石多为马鞍状白云石或异形白云石,较围岩显示出低碳、低氧和富锶特征,与典型构造热液成因白云岩一致,强度受构造控制明显,从造山带向盆地方向强度逐渐减弱。 |
| 关 键 词： | 热液白云岩 后期热液改造 外源热流体 二叠系 四川龙门山南段 |

| Abstract: | According to the study,the Permian dolomitite,dolomitic limestone and limestone are in gradual change and transitional relationship.The zebra-like structure is developed in dolomitite.The dolomite is mostly saddle-like or in unusual form.The C,O in dolomite are lower than those in the wall rock;however,Sr higher than that in the later,which is consistent with structural hydrothermal dolomitite.The intensity is controlled evidently by the structure,which is degraded from the orogenetic zone to the basin. |
| Keywords: | Hydrothermal Dolomitite Posterior Hydrothermal Reformation Exogenetic Thermal Fluid Permian S Section of Longmenshan Mt of Sichuan |
