This catalogue provides the most complete and revised work of Cenozoic genera as December 2019. It is result four exhausting years collaborative work. The first radiolarian genus was described in 1834 by Meyen, so this revision covers 185 research on polycystine radiolarians. Additionally, it concludes a pharaonic project taxonomy all radiolarians that started fifteen ago. main objective to pro...

[1] The Eocene-Oligocene (E/O) boundary interval marks one of the largest and most rapid changes in climate during the last 50 Myr. Because of a very shallow calcium carbonate compensation depth in the Eocene, as well as the reworking of sediments and hiatuses in the boundary zone, it has also been one of the most difficult stratigraphic boundaries to study in deep water marine sections, especi...

The age section ranges from Lacian 1 to Alaunian 1. succession is predominantly characterized by representatives genus Ancyrogondolella . Transitional morphologies towards faunas ...

manganese ore deposits occurred in various types of syngenetic, diagenetic and epigenetic mineralization in association with radiolarian cherts in colored melange of neyriz ophiolite in abadeh tashk area, eastern fars province. microscopic study and xrd analyses show a simple mineralogy for manganese compounds in all types. psylomelane and braunite are the primary manganese compounds in syngene...
