Licensed under the Creative Commons Attribution- NonCommercial-NoDerivatives 4.0 International http://creativecommons.org/ licenses/by-nc-nd/4.0/ 1 Abstract Permian strata from the Tieqiao section (Jiangnan Basin, South China) contain several distinctive conodont assemblages. Early Permian (Cisuralian) assemblages are dominated by the genera Sweetognathus, Pseudosweetognathus and Hindeodus with rare Neostreptognathodus and Gullodus. Gondolellids are absent until the end of the Kungurian stage—in contrast to many parts of the world where gondolellids and Neostreptognathodus are the dominant Kungurian conodonts. A conodont changeover is seen at Tieqiao and coincided with a rise of sea level in the late Kungurian to the early Roadian: the previously dominant sweetognathids were replaced by mesogondolellids.

ТОЛМАЧЕВА (ВСЕГЕИ) CТРАТИГРАФИЯ И ПАЛЕОНТОЛОГИЯ В НАУЧНОЙ ПРОГРАММЕ 34-й СЕССИИ МЕЖДУНАРОДНОГО ГЕОЛОГИЧЕСКОГО КОНГРЕССА (2012 г., Брисбен, Австралия) Рассматриваются сообщения, связанные с созданием Международной хроностратиграфической шкалы, выбором точек глобальных стратотипов границ (GSSP), обоснованием региональных зо- нальных последовательностей, комплексированием биостратиграфических и хемостратиграфических методов и др. Как показало сравнение с итогами предыдущей 33-й сессии Международного геологи- ческого конгресса (МГК), главным отличием современных палеонтолого-стратиграфических иссле- дований является их направленность на реконструкцию климатических особенностей геологического прошлого, оценку влияния палеоклиматов на биоту и характер осадконакопления. Обобщены доклады на секциях и заседаниях комиссий по системам, в которых авторы принимали непосредственное участие, а также дан аналитический обзор тезисов докладов 34-й сессии МГК. Ключевые слова: стратиграфия, палеонтология, 34-я сессия МГК. The main tendencies in modern stratigraphy and paleontology were discussed in the specialized sessions and meetings of the Stratigraphic Subcommissions, as well as in presentations of related sciences. Present review includes presentations connected with the creation of the International Stratigraphic Scale, proposition of the Global Stratigraphic Sections and Points (GSSP), compiling of the regional zonal successions, integration of methods of biostratigraphy and chemostratigraphy and many others. In comparison with previous 33th IGC, 2008, the modern paleontological and stratigraphic studies are different in intensification of investigations targeting the reconstruction of climatic features of the past, influence of paleoclimates to biota and sedimentation. The review is based both on synthesis of sessions and Subcommission meetings presentations where the authors took part and analytic review of the Abstract volume of 34th IGC. Key words: stratigraphy, paleontology, 34th IGC.

  • Possible Oil and Gas Fields in the Cretaceous Beds of Alabama
    424 OIL AND GAS FIELDS IN THE CRETACEOUS BEDS OF ALABAMA Possible Oil and Gas Fields in the Cretaceous Beds of Alabama BY DORSEY HAGER, * TULf\A, OKI,A. (New York Meeting, February, 1918) Downloaded from http://onepetro.org/TRANS/article-pdf/59/01/424/2176944/spe-918424-g.pdf by guest on 01 October 2021 THE possibility of oil and gas production in Alabama has been little considered as yet. Gas and some oil have been found in northwestern Alabama, near Birmingham, in the Pennsylvanian beds, but the oil and gas possibilities in the Cretaceous beds are not generally appreciated. The recent activity of oil companies in that State has attracted much attention, and in this paper the main structural and the general strati­ graphic features are described. :Four favorable areas are outlined. These contain folds of major interest. 'there are other favorable areas which have not been mapped,l Commercial pools discovered in this area would have the advantage of being near tidewater. Mobile, Ala., on the Gulf of Mexico, would be the logical site for refineries and shipping facilities. A pipe line could readily be laid to that city from the Hatchitigbee and the Jackson areas. The logical outlet for the Geneva and the Gordon areas would be Panama City, ma., on the Gulf of Mexico. TOPOGRAPHY The whole of the area under consideration lies in the Gulf coastal· plain and slopes gently to the southwest and west. The elevations vary from 200 to 400 ft. (60 to 121 m.) above sea level. The streams have . sunk their channels into this gently sloping plain, the main drainage flowing south or southwest into tho Gulf of Mexico.
