笔者根据220个岩体地质资料及120个岩体同位素地质年龄数据,描述了中国碱性侵入岩的空间分布和年代特征。在中国可分出沿深断裂展布的18条碱性侵入岩带,讨论了岩带展布与周边板块构造活动的关系。鉴于有大量华力西期的碱性侵入岩,这些岩体具深源特征,推测在华力西时期中国地幔底辟作用甚为强烈。此外,除了非造山及造山后碱性花岗岩外,也产出造山末期碱性花岗岩,当时的区域构造活动具挤压性质。最后讨论了四川冕宁县牦牛坪英碱正长岩形成的构造环境
According to the geologic data of 220 rock masses and the geological data of 120 rock mass isotopes, the author describes the spatial distribution and age characteristics of alkaline intrusive rocks in China. In China, 18 alkaline intrusive rock belts distributed along the deep fault can be separated and the relationship between belt spreading and the tectonic activities of the surrounding plates is discussed. In view of the large number of Variscan alkaline intrusive rocks, these plutons have deep-sourced features suggesting that the mantle diapirism in China during the Variscan period was very strong. In addition, in addition to non-orogenic orogenic orogenic granites, alkaline granites were also produced at the end of the orogeny. At that time, regional tectonic activities were squeezed. Finally, the tectonic environment formed by the yakaping alkalic syenite in Mianning County, Sichuan Province is discussed
