Ak.A.Ali-Zadeh – one of the eminent geologist-scientists and big science organizer. Field of scientific interests of Ak.A.Ali-Zadeh is regional stratigraphy of Azerbaijan Cretaceous deposits. He supervised and developed stratigraphic scheme for Azerbaijan Cretaceous deposits, large paleontological-stratigraphic material was analyzed and generalized which could reflect contemporary ideas of geological processes; formation of sedimentary, volcanogenic-sedimentary formations, distribution and development of Cretaceous fauna.

On the base of many years thorough studies Ak.A.Ali-Zadeh formulated the basic concepts of study for Cretaceous Mollusk fauna (belemnites) of Azerbaijan.

There is their classification and phylogeny, morphofunctional analysis; the principles of paleo-biogeographic zoning were worked out; ecology and paleontology problems were covered.

Ak.A.Ali-Zadeh himself identified the stages of spatial-temporal distribution for the Cretaceous Invertebrates in Mediterranean and revealed here appropriate paleo-biogeographic taxons. Study of morphogenesis in historical aspect, definition of tendency in populations nature alteration, identification of heritable morphological changes allowed him to restore a general evolution process of various belemnoides groups.

Ak.A.Ali-Zadeh carried out basic research on methods of biogeochemical zonation of the Cretaceous basins in Caucasus and on study of geochemical conditions of Paleobasins as evolution factor. On analysis results of microstructural, chemical and crystallochemical peculiarities of matters in skeleton formations of fossils the following was revealed – patterns of migration and concentration for various chemical elements, paleophysiological peculiarities for some taxons, and also there is a description of geochemical ecology for the Cretaceous Invertebrates. For the first time absolute values of Paleo-temperatures of Azerbaijan Cretaceous basins were determined by isotopic Paleothermometry method relatively O18 and O16.

Possessing extensive knowledge Ak.A.Ali-Zadeh authorizes in solving the questions of regional geology, tectonics, ore geology and hydrogeology; over the last years he has paid a great attention to the geoecology – new scientific direction which became a priority in his Institute activity. The representatives of scientific society such as A.P.Pavlov and G.Y. Krymgoltz appreciate a great contribution of Ak.A.Ali-Zadeh to study of fossils – endocochlia cephalopoda and his merits as Azerbaijan scientist in study of Cretaceous belemnites. In honour of Ak.A.Ali-Zadeh a new family of belemnoids was named – “Akifibelids” (1984).

He was awarded by Azerbaijan Republic State Prize (jointly with authors team) for a number of works on paleontology and stratigraphy of the Cretaceous deposits (1991).
