摘要: About 10 km SW from Hanchung,there rise rocky hills of the Liangshan Area which iscovered with little gravel and dissected by streams.Thus we have access to many excellent na-tural sections.Being highly fossiliferous the relative ages of strata may be exactly determined.With different cycles of sedimentation the rocks varied in lithological characters while under stressof crustal movements hiatuses were formed.From all the facts accumulated the writer will disscusssome important stratigraphical problems concerning this region.
