Towards the study of chromite iron ore deposits
Abstract
In this article, the author attempts to present in general terms his views, on the one hand, on the methodology for studying chrome deposits in the most general sense, and on the other hand, on the geological nature of these deposits. The author himself has extensively studied primarily the platinum-bearing chromite iron ores of the Urals. For purposes of identification, non-platinum-bearing chromites were also studied alongside this work. The latter were studied in more detail in Transcaucasia (in the area of Lake Gokcha), as well as in the Northern Caucasus (in the area of the Bolshaya Laba River). We can outline the following genetic types of chrome-spinel formations: 1) chrome-spinels formed in the earlier magmatic period; 2) accumulations of chrome-spinels formed in the later magmatic period, when the main mass of the host rocks had already been nearly formed; 3) chrome-spinels formed by hydrothermal processes, mainly during the serpentinization of rocks.
