Dr Ömer Elitok is a geologist/petrologist with a strong interest in structure and petrology of ophiolites in Turkey, neotectonics of Turkey, petrology of plutonic rocks, tephrochronology and geochemistry of Cenozoic volcanic rocks in Turkey. His teaching interests include plate tectonics, mantle dynamics and global tectonics, ophiolite and oceanic lithosphere, magmatism and tectonic settings, petrology of basaltic rocks, volcano morphology, field geology, Quaternary, carbonate petrology, optical mineralogy, special microscopic petrography. He did his graduate work (MS and PhD) in the University of Suleyman Demirel. He is still lecturer at the Department of Geological Engineering in the Engineering Faculty of Suleyman Demirel University, Turkey. He teaches and tutors national and international MSc and PhD students. He visited some of European universities in the framework of specific scholarship programmes, university projects, scientific cooperations. He believes that geology is a lot like detective work. Stratigraphy, a branch of geology, is the science of describing the vertical and lateral relationships of different rock formations formed through time to understand the earth history. These relationships may be based on lithologic properties (named lithostratigraphy), fossil content (labeled biostratigraphy), magnetic properties (called magnetostratigraphy), chemical features (named chemostratigraphy), reflection seismology (named seismic stratigraphy), age relations (called chronostratigraphy). Also, it refers to archaeological deposits called archaeological stratigraphy. Stratigraphy is built on the concept “the present is the key to the past“ which was first outlined by James Hutton in the late 1700s and developed by Charles Lyell in the early 1800s. This book focuses particularly on application of geophysical methods in stratigraphic investigations and stratigraphic analysis of layered basin deposits from different geologic settings and present continental areas extending from Mexico region (north America) through Alpine belt including Italy, Greece, Iraq to Russia (northern Asia).
