以崂山I A型花岗岩为例 ,通过再造这一复合花岗岩体不同单元的冷却史 ,从热演化角度讨论了I A型花岗岩的形成、定位及与造山带隆升和构造环境变迁的关系 .从I型花岗岩到A型花岗岩这一完整的花岗岩谱系所呈现出的冷却速率逐渐变快的趋势 ,可能是花岗岩由封闭的压性环境向开放的张性环境转化的热演化标志 . Taking Laoshan IA type granite as an example, the formation and location of IA type granite and its relationship with the uplift of the orogenic belt and the tectonic environment change are discussed from the perspective of thermal evolution by re-creating the cooling history of different units of this composite granite body. The complete granite lineage from Granite to A-type granite tends to show a faster cooling rate. It may be a sign of thermal evolution of granites from an enclosed and compressive environment to an open and tensioned environment.
