Research and Publications



    • Mineralogy, petrology, and geochemistry research focus on mineral chemistry and mineral paragenesis of various mineral phases crystallizing from magmatic systems. It also includes the nature, source, and origin of the various peralkaline to peraluminous, and mafic to a felsic spectrum of magmatic complexes, their petrological, chemical, and isotopic evolution, and the tectonic regimes of magma emplacement, as well as rare-metal mineralization. This line of research helps in defining the magmatic-tectonic stages of evolution of the continental crust and its mineral deposits (Dr. A. Abdel-Rahman). 

    • Geophysics and Petrophysics research are focused mainly on the deep 3-D crustal and upper mantle structures using seismological data (phase arrivals, regional, and teleseismic waveforms) from local, regional, and global earthquakes in order to delineate anomalous structures and the deep velocity anomalies and their impact on the occurrence of major destructive earthquakes. The research also integrates and combines such data with exposed major structural features in Northeastern Africa, the Middle East, Turkey, etc. In addition, the research also deals with the petrophysical and geotechnical characteristics of sedimentary rocks and their applications in the oil industry and engineering domains (Dr. M. Salah).  

    • Hydrogeology research focuses on the development of new methods for the assessment of the quantitative vulnerability of karst aquifers including numerical simulation of integrated karst systems, characterization of fast and slow pathways in karst aquifers, and the characterization of transport behavior using specific indicators (Dr. Joanna Doummar).  

    • Structural Geology and tectonics current research interests include topics such as: Understanding the timing of the structural evolution of the Lebanese Restraining Bend. Understanding the current tectonic activity of the main fault branches in Lebanon and their impact on the seismic hazard of the country. Investigating the tectonic activity of the E-W trending faults in Lebanon and their impact on current and potential hydrological dam projects. (Dr. Tony Nemer).  

    • Micropaleontology and stratigraphy research is focused on oceanic nutrient cycling, ecology, and climate. It also includes the study of the stratigraphy of calcareous nannofossils in Lebanese sections, and Plankton evolution (Dr. Ali Haidar).
