SOME TENTATIVE OPINIONS ON THE PROBLEM OF“SJARA-OSSO-GOL SERIES”

Abstract

If we go back to the known literatures,we may find out that the term“Sjara-osso- gol Formation or Series”was not formally proposed by P.Teilhard de Chardin,nor by any other geologist.However,since long time ago,Chinese Quaternary geologists al- ways consider that it is a name of a special geological formation of stratigraphical, palaeontological and archaeological importance.But since that we have learned that Chinese Quaternary geologists have very widely divergent opinions,concerning the geo- logical age and mode of deposition of this interesting formation,we may expect that hot controversy will be raised,like in the case of“Sanmenian”or“Sanmen Series”of early Pleistocene.
