Coralline red algae from the Lower Pliocene Shagra Formation of Wadi Wizer, Red Sea coast, Egypt: Biofacies analysis, systematics and palaeoenvironmental implications
Coralline red algae are highly abunadant and well diversified in the well exposed carbonate deposits of the Lower Pliocene Shagra Formation at Wadi Wizer, Red Sea coast, Egypt. Lithostratigraphically, the Shagra Formation unconformably overlies the Late Miocene Marsa Alam Formation and underlies the Quaternary deposits. This carbonate facies is dominated by different assemblage of coralline red...
متن کاملPreservation of Biological Signature within Impact Melt Breccias, Haughton
Introduction: The response of organic matter to impact events is of widespread interest for what it tells us about the likelihood of survival of life and/or fossilized biological signatures [1,2,3] following impacts. This is relevant to the history of life on Earth, and to our exploration of other solar system bodies, including Mars. The Tertiary Haughton Impact Structure, Cana-dian High Arctic...
متن کاملX-ray Mapping Investigations of the Monazites from the Mt Weld Deposit -Compositional Variance as an Indicator of Provenance
The Mt Weld lanthanide deposit in central Western Australia is considered to be one of the largest high grade deposits known in the world, first reported as a carbonate and phosphate rich ultramafic silicate intrusion that contained a resource of the Lanthanide series [1]. It has been dated between 1.6 – 2.0 billion years, where the formation of a carbonate layer in the cooling melt created a p...
متن کاملDiversity, growth forms and rhodolith distribution: factors controlling the fabric of coralline algae of the early Miocene deposits, Cairo – Suez road, Egypt
The Lower Miocene deposits in Gabal Gharra, Cairo – Suez District, unconformably overlies the Oligocene and Eocene deposits. They consist predominantly of regressive and transgressive mixed siliciclastic / carbonate sediments of shallow marine environments. The Lower Miocene deposits are represented lithostratigraphically by the Gharra Formation that comprises four members, from base to top: Ag...
متن کاملShock Metamorphism of Impactite Lithologies of the Icdp Chicxulub Drill
(1) Upper sorted suevite (794.63 – 807.75 m) and (2) Lower sorted suevite (807.75 – 823.25 m): The dominating component in both units of the sorted suevite are melt particles of shock stage IV. Two different textural types of melt particles were observed: (1) brownish to pale green silicate melt particles with flow texture, vesicles and schlieren; and (2) dark aphanitic particles with inclusion...
