| 摘 要： | 野外地质调查和详细的岩性岩相学及构造学研究表明，赣中变质岩带由深层次结晶基底和浅层次褶皱基底组成。结晶基底中除斜长角内岩为正变质岩体，其它变质岩均为副变质，斜长角闪岩原岩为基性火成岩，副变质岩原岩主要为杂砂岩，其次为长石砂岩，岩屑砂岩，粘土岩，褶皱基底其原岩为泥质岩，含炭泥质岩（炭质）硅质岩。 |
| 关 键 词： | 变质岩 原岩恢复 江西中部 |

| Abstract: | Field geological survey and detailed lithologic-lithofacies and structural study have revealed that the Central Jiangxi Metamorphic Belt is composed of deep-seated crystalline basement and shallow-seated folded basement.In the crystalline basement,the protolith of amphibolite(an ortho-metamorphic rock)is a basic igneous rock,while that of other metamorphic rocks(a para-metamorphic rock)is largely a graywacke with minor arkose,lithic sandstone and clay rock.In the folded basement,the protoliths are pelitic rocks,carbonaceous pelitic rocks and(carbonaceous)siliceous rocks. |
| Keywords: | metamorphic rock restoration of protolith Central Jiangxi |
