Triploporella ? edgelli n. sp., a new Dasycladalean alga from the Lower Cretaceous of Lebanon          下载免费PDF全文

The Dasycladalean assemblage of the Jezzinian strata (uppermost Barremian–lowermost Aptian) of Lebanon consists of two organo‐genera and eight genera with eleven species, including eight Triploporellaceae. Although Triploporella marsicana (Praturlon, 1964) was reported by Saint‐Marc from the same interval, it is not found in our material. However, a lookalike, which is herein described as Triploporella ? edgelli n. sp., is identified. This new species has cyst‐containers within the primary segments of its laterals but, because it lacks calcified secondary segments, it is left in open nomenclature.  相似文献   

Petrography of Cenozoic volcanic rocks of Egypt (UAR)     

Prof. Dr. Essam E. El-Hinnawi  M. A. Abdel Maksoud 《International Journal of Earth Sciences》1968,57(3):879-890

The detailed petrographical characters of Cenozoic volcanic rocks of Egypt are given. Two pétrographic provinces have been identified: Abu Zaabal-Abu Rawash-Qatrani province and Cairo-Suez-El-Bahnasa-Tahna province. The rocks of the first one are doleritic basalts, while those of the second one are typical basalts. The weathering of the doleritic basalt, as especially observed in quarries, was also studied.

Zusammenfassung Der detaillierte petrographische Charakter von känozoischen vulkanischen Gesteinen aus Ägypten wird dargestellt. Zwei petrographische Provinzen sind identifiziert worden: die Abu Zaabal-Abu Rawash-Qatrani-Provinz und die Cairo-Suez-El-Bahnasa-Tahna-Provinz. Die Gesteine der ersten sind doleritische Basalte, während die der zweiten typische Basalte sind. Die Verwitterung der doleritischen Basalte, insbesondere in Steinbrüchen beobachtet, wird ebenfalls dargestellt.

Résumé Le caractère détaillé pétrographique de roches volcaniques cénozoiques d'Egypte est démontré. On a identifié deux provinces pétrographiques: la province Abu Zaabal-Abu Rawash-Qatrani et la province Caire-Suez-El-Bahnasa-Tahna. Les roches de la première sont des basaltes doléritiques, tandis que celles de la deuxième sont des basaltes typiques. L'altération des basaltes doléritiques, en particulier observée dans des carrières, a aussi été étudiée.

Preliminary report on a dinosaur tracksite from Lower Cretaceous strata in Mount Lebanon     

Raymond Gèze  Isabelle Veltz  Jean-Claude Paicheler  Bruno Granier  Roland Habchi  Dany Azar  Sibelle Maksoud 《Arabian Journal of Geosciences》2016,9(19):730

A dinosaur tracksite was discovered in Batha on the side of the road from Harissa to Ghosta (Keserwan, Lebanon). About ten trackways are exposed at the top of two beds of Lower Cretaceous limestones over an area of approximately 1000 m². These footprints were probably made by at least two dinosaur species, Sauropoda and either Theropoda or Ornithopoda. The site, which is the first record from Lebanon, should be protected to allow further scientific investigations.  相似文献
