| 摘 要： | 对山东莒南日照地区榴辉岩与不同围岩的接触关系进行研究发现：包裹榴辉岩的斜长角闪岩有窄的细粒边；榴辉岩在变质地层及超镁铁岩中呈夹层状产出，与超镁铁岩相伴产出的榴辉岩有角闪石化边；变质含霓石花岗岩及闪长玢岩侵入榴辉岩。认为榴辉岩是“就地的”．其原岩类型较复杂。其形成时代可能为新元古代。 |

| Abstract: | This paper studied the contact relation between eclogite and its country rock in Junan-Rizhao area.The research showed that there were fine rims in the amphibolites with eclogite enclosed in them.Eclogite occurred as intercalated bed in metamorphic stratum and ultrabasic rock. There were also hornblende rims in eclogite when it contacted with ultrabasic rock.Since the metamorphic granite and diorite-porphyrite intruded into eclogite,it was inferred that the eclogite was likely the native block and UHP which formed probably in Neoproterozoic. |
| Keywords: | UHP eclogite contact relation Junan-Rizhao area |
