| 中文摘要: |
| 通过系统的花岗岩地质、岩石学、矿物学、岩石化学、稀土元素地球化学、同位素地球化学等方面研究,认为玲珑岩体的片麻状花岗岩和中粗粒二长花岗岩同来源于新太古界-下元古界TTG岩系,燕山期沂沭裂谷强烈活动并产生大量热流,导致地壳局部熔融,并在构造挤压下发生底辟侵位,形成玲珑复式花岗岩基。 |
| 英文摘要: |
| Systematic study on geology, mineralogy, petrology, petrochemistry, REE and isotopic geochemistry reveals that gneissic granite and monzonitic granite in Linglong granitic body are derived from Neoarchean-Lower Proterozoic TTG rock series. strong fracturing of Yishu fault gave rise to large heat flow leading to partial melting materials. Diapirism of the melts took place under tectonic pressure to form the complex Linglong granitic batholith. |
