摘　　要：甘肃北山北部霍勒扎德盖地区,分布着一套火山—沉积地层,对其进行岩石地层、区域对比及地层年代等方面的研究,划归扫子山组,并依据组内岩性差异划分为4个岩性段。该组的确定对研究哈萨克斯坦板块南缘地质演化历史有重要意义。A suite of volcanic-sedimentary strata exist in the Herzhadegai area, northern section of Beishan in Gansu Province, which is determined as Saozishan Formation through the study of geological ages and lithostratigraphic and regional correlation, meanwhile, subdivided into 4 lithological members in terms of their litholog- ical differences. It will be of significance for studying geological evolution history of the southern edge of Kaza- khstan Plate.
