      <abstract xml:lang="ru">
        <p>В настоящей статье автор делает попытку в общем виде изложить свои взгляды, с одной стороны, на методику изучения хромовых месторождений в самом общем виде, а с другой — на геологическую природу этих месторождений. Сам автор много занимался изучением преимущественно уральских платиноносных хромистых желеяков. В целях идентификации попутно с этим изучались и неплатиноносные хриты. Более детально последние изучались в Закавказье (в районе оз. Гокча), а также на Северном Кавказе (в районе р. Б. Лабы). Мы можем наметить следующие генетические типы образований хромшпинелидов: 1) хромшпинелиды, образованные в более ранний магматический пиод; 2) скопления хромшпинелидов, образованные в более поздний магматеский период, когда главная масса вмещающих пород была уже почти сфоирована; 3) хромшпинелиды, образованные гидротермальными процессами, глав­ным образом во время серпентинизации пород.</p>

        <p>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.</p>
