摘要: 通过对辽宁省3个地层小区（太子河、大连、辽西）的太原组岩性、生物面貌、上下接触关系的调查，认为辽宁省境内的岩石地层太原组的地质年代在各地是不同的.在太子河地区（包括东部浑江流域的桓仁地区）太原组的年代是晚石炭世，不穿时到其他时代；而大连地区和辽西地区的太原组的年代为晚石炭世-早二叠世，是具明显穿时性的岩石地层.

Abstract: With survey on lithology, paleontology and contact relationship of the Taiyuan Formation in three stratigraphic areas, namely Taizihe, Dalian and Western Liaoning, the author thinks that the geological ages of lithostratigraphic Taiyuan Formation vary from place to place in Liaoning Province. The age of Taiyuan Formation in Taizihe area is the Late Carboniferous, without diachronism; whereas that in Dalian and Western Liaoning, is the Late Carboniferous-Early Permian, with apparent diachroneity.
