用Ｋｏｂｅｒ方法测定了平邑县、蒙阴县普照寺闪长岩、松山－邱子峪二长花岗岩、周公地－花果庄－宁子洞花岗闪长岩、余粮店辉长岩和东近台英云闪长岩的锆石年龄。多数样品中的锆石反映了多于一期的地质记录，其中东近台英云闪长岩中的锆石（２８６８±１３Ｍａ、２７１２±５Ｍａ、２７１１±７Ｍａ和２５９８±６Ｍａ误差均为２σ），反映了本区最老的地质记录；部分样品中的２４００Ｍａ可能反映了太古宙最后一期的地质作用；而大部分样品中的锆石显示了２５００Ｍａ和２６００Ｍａ的地质记录，即岩浆活动多集中于２６００Ｍａ、２５００Ｍａ和２４００Ｍａ。这与太古宙末期地质活动重新加剧有关。
The Kober method was used to determine the relationship between the Pingyi County, Mengyang County, Puzhao diorite, Songshan-Qiuziyu granite, Zhougongdi-Huaguoguang-Ningzidong granodiorite, Zircon Age of Near-Taiying Dianite. Most of the zircons in the samples reflect more than one geological record. The zircons (2868 ± 13Ma, 2712 ± 5Ma, 2711 ± 7Ma and 2598 ± 6Ma errors are 2σ) , Reflecting the oldest geologic record in the area; some of the samples at 2400 Ma probably reflect the geological effects of the Archean last phase; while the zircons in most samples show the geological records at 2500 Ma and 2600 Ma, ie, the magmatic activity is more concentrated At 2600Ma, 2500Ma and 2400Ma. This is related to the re-aggravation of geological activities in the late Archean.
