招远—莱州地区花岗岩类锆石 Ｓ Ｈ Ｒ Ｉ Ｍ Ｐ 研究表明，该区花岗岩类含有大量不同时代的继承锆石。３４４６ ±２ Ｍａ ～３１１４ ±４ Ｍａ 继承锆石的发现，表明鲁东地区存在古太古代硅铝核。大量印支期继承锆石的年龄（ 平均年龄２１９ Ｍａ） 与华南、华北克拉通碰撞时代一致，推测这些锆石极可能来自其源岩———华南、华北克拉通碰撞造山花岗岩，从而否定了玲珑型花岗岩主要是由胶东岩群交代 重熔形成的传统认识。郭家岭型花岗闪长岩中含有较多新太古代和古元古代继承锆石，表明其源岩有较多的胶东岩群和荆山岩群变镁铁质岩石和（ 或） Ｔ Ｔ Ｇ 岩系的硅铝质岩石。
The Zhaoyuan-SZ R I M P granitoids in the Laizhou area show that the granitoids in this area contain a large number of successional zircons from different ages. The succession of zircon from 3446 ± 2 Ma to 3114 ± 4 Ma shows that the ancient Archean Si-Al cores exist in Ludong area. The age of a large number of Indosinian zircons (mean age 219 Ma) is consistent with the collision times of South China and North China Craton. It is speculated that these zircons most likely originated from the source rocks of South China and North China Craton rock orogen, Delicate granite is mainly composed of Jiaodong petroglyphs formed by the traditional understanding of remelting. The Guojialing type granodiorite contains more Neo-Archean and Paleoproterozoic inherited zircons, indicating that there are more Jiaodong and Jingshan Group mafic rocks and / or T G Silurian rocks of the rock series.
