摘要
冀东太平寨地区紫苏花岗岩的矿物学研究结果表明,该类岩石中的主要组成矿物具有残晶相和结晶相矿物共存特点。残晶相和结晶相矿物与围岩中同类矿物对比研究表明,该区的紫苏花岗岩类是由其围岩—石英闪长质-英云闪长质紫苏斜长片麻岩深熔而成。
The co-existence of residual and crystaline minerals in charnockites in Taipingzhai area, eastern Hebei Province,is discovered through detail study on minerals. The study of corresponding minerals between charnockites and its country rock (quartz dioritic-tonalitic hypersthene plagioclase gneiss) indicates that charnockites in Taipingzhai area was derived from anatexis of its country rocks.
