The studies on the geochronology for deep xenoliths,their host alkalic porphyries and mineralizing quartz viens show that the diagenetic age of the deep xenoliths are older than that of their host alkalic porphyry,and the alkalic porphyry's diagenesis and associated mineralization are almost sa.
对包体岩石和寄主富碱斑岩及其成矿石英脉的地质年代学研究显示,深源岩石包体的成岩年龄大于寄主富碱斑岩,而富碱斑岩的成岩与成矿是基本同时的。
The developmental trend of international geochronology in recent one hundred years and Chinese geochronology from 1980 s is discussed through the statistics of geochronological documents.
