To the study of chromium iron ore deposits

Abstract
In this article, the author makes an attempt to present in general his views, on the one hand, on the methodology for studying chromium deposits in the most general form, and on the other, on the geological nature of these deposits. The author himself has been involved in the study of predominantly Ural platinum-bearing chromium iron ores. For identification purposes, non-platinum-bearing chromites were also studied at the same time.The latter were studied in more detail in Transcaucasia (in the area of Lake Gokcha), as well as in the North Caucasus (in the area of the Bolshaya Laba River). We can outline the following genetic types of chrome spinels formations: 1) chrome spinels formed in an earlier magmatic period; 2) accumulations of chromespiedids formed in a later igneous period, when the main mass of the host rocks was almost formed; 3) chrome spinels formed by hydrothermal processes, mainly during serpentinization of rocks.
