  • Mineralogy and diagenetic impacts on chemical composition of Paleozoic mudrocks, southwestern Sinai, Egypt

    • Authors: Abayazeed, S.D.;  Advisor: -;  Participants: Ibrahim, A.M.; Alshami, Abdalla Soliman; Saadawy, D.A. (2019)

  • The present study deals with mineralogy, diagenesis, and their impact on chemical composition for early Paleozoic, Cambro-Ordovician, (Adediya and Abu Hamata formations) and late Paleozoic, early Carboniferous, (El Hashash and Magharet El Maiah) mudrocks at the southwestern Sinai area. Mineralogical study reveals the presence of kaolinite and illite clay minerals.

  • Trematode cercarial fauna obtained from the field-collected freshwater snails Lymnaea natalensis in Egypt

    • Authors: Ibrahim, A.M.;  Advisor: -;  Participants: Ahmed, A.K. (2019)

  • From total examined snails, it was found that the infected snails included five types of the cercarial stages beside Fasciola cercariae and three types of metacercariae. These cercariae were xiphidio cercariae, gymnocephalus, echinostome cercariae, virgulate cercariae, Echinochasmus pelecani, and Palaeorchis cercariae. The infection rate in snails collected from ElZeidia was the higher infection rate (84%) than others from Oseem (76%) and ElMansuria (62%).
