BOUNDARIES BETWEEN DIVISIONS OF THE PERMIAN IN SOUTHERN EUROPE AND SOUTHERN ASIA |
| |
Abstract: | The literature reflects differences of opinion on the boundaries between the several divisions of the Permian in certain classical sections. The Sosio limestone of Sicily should be referred to the lower portions of the upper, rather than lower, division of the Permian. Accordingly beds with higher fusulinids in other Eurasian sections must represent a similar stratigraphic position. The fauna of the Productus zone of the Salt Range is considered and it is concluded that the lower member of this limestone is Lower Permian; the two upper members represent the Upper Permian. The Jisu-Honguer limestone of southeast Mongolia should be referred to the lower part of the Upper Permian. The fauna of these deposits was described by Grabau.—Auth. English summ. |
