摘　　要：本文简要叙述了甘肃侵入岩的时空分布、构造岩浆旋回和构造岩浆岩带划分,将甘肃侵入岩划分为4个构造岩浆旋回、5个构造岩浆岩省、10个构造岩浆岩带,简述了各构造岩浆岩省侵入岩基本特征和岩石构造组合特征,探讨了其形成的大地构造环境,利用现有资料初步建立了甘肃侵入岩年代格架。The paper briefly introduced the spatial and time distribution, and the classification of tectonic magmatic cycle and tectonic magmatic rock zone of magmatic rock in Gansu Province, which are divided into 4tecto-magmatic cycles, 5 tectonic magmatic rock provinces, and 10 tectonic magmatic rock zones. Then, it is summarized each tectonic magmatic rock province about the characteristics of intrusive rock and petrologic-tectonic assemblage, discussed geotectonic environment of formation, and established intrusive age framework.
