Abstract
This paper is a study of volcanogenic bentonite. We examine the geological structural settings of the deposits, the paleogeographic environment of sedimentation, structural and textural features of the rocks, and their diagnostic features. We have identified ore-controlling factors in the generation of volcanogenic and hydrothermal bentonite. Comparative analysis has been performed of the original volcanogenic material sampled at deposits in Russia and abroad. The Dash-Salakhly deposit (Republic of Azerbaijan) and a bentonite-bearing province on Sakhalin Island were studied to find how bentonites of different genesis were formed. These studies provide evidence that the composition of the parent material for bentonite varies in a wide range, between basalt and rhyolite. The main factor that controls the generation of bentonite is the type of the sedimentation basin and physicochemical conditions rather than the composition of the parent material.
期刊介绍：
Journal of Volcanology and Seismology publishes theoretical and experimental studies, communications, and reports on volcanic, seismic, geodynamic, and magmatic processes occurring in the areas of island arcs and other active regions of the Earth. In particular, the journal looks at present-day land and submarine volcanic activity; Neogene–Quaternary volcanism; mechanisms of plutonic activity; the geochemistry of volcanic and postvolcanic processes; geothermal systems in volcanic regions; and seismological monitoring. In addition, the journal surveys earthquakes, volcanic eruptions, and techniques for predicting them.
