Dzhanelidze, A. I. Geological Observations in Okriba and Adjacent Parts of Racha and Lechkhumi (Geologicheskie nablyudeniya v Okribe i v smezhnykh chastyakh Rachi i Lechkhuma). (Georgian Branch of the USSR Academy of Sciences).

This 1940 monograph is a monumental work in the history of Caucasian geology, authored by the patriarch of the Georgian geological school, Alexander Ilarionovich Dzhanelidze (1888–1975). Published by the Georgian Branch of the USSR Academy of Sciences just before the full-scale regional institutionalization of the Academy, this volume represents the culmination of years of rigorous field research in the complex tectonic regions of Western Georgia.
The book focuses on the structural and stratigraphic analysis of Okriba, Racha, and Lechkhumi—areas vital for understanding the orogeny of the Greater Caucasus. Dzhanelidze provides an exhaustive description of the Jurassic and Cretaceous deposits, meticulously detailing the lithological variations and paleontological markers that define the regional stratigraphy. His observations on the tectonic evolution of these districts provided a foundational framework for future mineral exploration and civil engineering in the Georgian highlands.
Richly illustrated with technical drawings, site-specific diagrams, and photographs of geological outcrops, the work also includes two significant folded plates featuring complex maps and cross-sections. These visual aids are essential for tracing the folding and faulting patterns characteristic of the Racha-Lechkhumi fault zone.
As a primary source, this volume is indispensable for geologists specializing in the Alpine-Himalayan orogenic belt and historians of science documenting the development of academic research in the Georgian SSR. Encased in its original publisher's cloth binding, this 400-page academic tome is a rare and prestigious addition to any collection of Caucasian scientific literature or regional geological surveys.
