| 摘 要： | 程裕淇确定了泰山岩群雁翎关组、山草峪组、柳杭组地层划分，在斜长角闪岩中发现残存的变余杏仁状构造和岩流特征，正确区分了变基性熔岩流、变火山凝灰质岩和变基性脉体。原化马湾组黑云斜长片麻岩为新太古代早期条带状英云闪长质片麻岩。富山背斜的片麻状奥长花岗岩锆石SHRIMPU—Pb年龄（2612±20）Ma，其侵入的具变余气孔状充填构造的斜长角闪岩属于雁翎关组；而李家庄倒转向斜核部的柳杭组含砾黑云变粒岩中最年轻的碎屑锆石SHRIMPU—Pb年龄（2524±7）Ma。

| Abstract: | The division of Yanlingguan group, Shancaoyu group and Liuhang group in Taishan formation has been determined by CHENG Yuqi academician. Residual amygdaloidl structure and rock flow characteristics have been found in amphibolite, and meta--basic lava flow, meta--volcanic tuffaceous rocks and meta--basic veins have been correctly distinguished. Bearing biotite plagioclase gneiss in original Huamawan group is banded tonalite gneiss in early Archean period. SHRIMP U--Pb zircon age of gneissic trondhjemite in anticline of Fushan mountain is （2612 ± 20） Ma. Plagioclase amphibolites with vesicular filling structure belongs to Yanlingguan formation; while SHRIMP U--Pb age of the youngest fragements in gravel--bearing biotite leptynite in the core of Lijiazhuang inverted oblique in Liuhang group is （2524 ± 7） Ma. |
