Specialization: Geology of the Central Segment of the Alpine-Himalayan Belt.
The basic scientific research lines are: general and regional geology, seismic tectonics, seismic hazard assessment, geodynamics phanerozoic biostratigraphy, lithogenesis of sedimentary and volcanic-sedimentary formations, geology and petrology of magmatic and metamorphic formations, volcanology, geology of mineral resource deposits, metallogeny, geochemistry and mineralogy of hydrothermal ore formations, geological informatics, engineering geology and hydrogeology, efficient use and protection of geological environment, mapping and assessment of natural landscape geosystems.
Geology-oriented
research institutes and higher education establishments of
In the past years, there were carried out fundamental investigations in various fields of geology and geography, which resulted in several dozens of monographs and numerous scientific publications.
Main results
Biostratigraphy. The schemes of stratigraphic dissection of
the Phanerozoic deposits of
In the field of the theoretical geodynamics and tectonics, Academician A. T. Aslanian has developed a hypothesis on free nutational oscillations of the poles, the origin of the Earth's magnetic field, and a quantified model of the substance composition and internal structure of the Earth, and obtained quantitatively justified evidences on the Earth's radius decrease.
The seismic hazard assessment (seismic zonation, and long-term earthquake forecast) in the Armenian Highland was made, a geodynamic model of newest stage was proposed, and the active tectonics map was drafted.
The outcrops of the crystalline basement of the Baikalian and Hercinian consolidation age were revealed, their initial compositions of metamorphic facies and the geodynamic conditions of their formation were determined.
"The Map of Magmatic and Metamorphic Formations of the Armenian SSR" and "The Map of Crystalline Basement of Armenia" were drafted.
Structural-and-geodynamic conditions of area volcanism manifestations were revealed, and regularities and genetic peculiarities of ignimbrite volcanism were found out "The Maps of Mesozoic and Cenozoic volcanic formations" were drafted.
Geological-and-structural conditions for
localization, formation and location regularities of the commercial deposits of
A new type of gold-ore mineralization localization was distinguished.
There were compiled "The World
Metallogenic Map", various-scale metallogenic and forecasting-metallogenic
maps of Lesser Caucasus and
The engineering-geological technique for
classification of mountainous areas was developed, various-scale
engineering-geological maps and engineering-geological zonation maps for
individual regions and towns of
Geoinformation systems. Development of unified automated system on geological environment
