| 摘 要： | 贵州从江及其毗邻地区的岩浆岩较发育,其岩类较多,有基性岩、超基性侵入岩、酸性侵入岩及基性火山岩。笔者通过收集最新的区域地质调查和同位素年龄测定结果等,对其形成时代进行了探讨,认为岩浆岩活动的高峰期为Ca.825Ma左右,即新元古代早期。 |

| Abstract: | Magmatic rocks fairly developed in Chongjiang and its neighboring area of Guizhou,which complex rock species consist of ultramafic!rock,basic intrusive rock,acid intrusive rock and basic volcanic rock.The writers elaborate its formed age based on newly collected geology and dating data,and consider peak period of magmatic activity is approximately ca.825Ma.that is lower Neoproterozoic. |
| Keywords: | magmatic rock formed age Chongjiang and its neighboring area of Guizhou |
