| 摘 要： | 永平花岗岩属陆壳改造型,是继海西一印支期混合岩的基础上进一步重熔、交代而成的具明显侵位特征的异地一半原地花岗岩,具有物质来源浅,形成温度较高,侵位浅,受改造时间长等特点。经历了地槽沉积-加里东期变质-海西-印支期混合岩化-燕山期的进一步重熔、交代这样漫长复杂的历史。

| Abstract: | Yong Ping granite belong to the type of anatexis of the Continent crust, which is the result of the further anatexis and replacement of migmatite at the Hercynian-indochian period, which is the defferent-half original region granite that is obviously of the feature of emplacement and has the characters of the source of substance and emplacement shallowly, forming temperature highly,reforming period longly, It's formation undergoes very long complicated history-Geosynclinal deposit
-Caledonian metamophism - Hercynian~Indochina migmatization-Yen shan further anatexis and replacement. |
