      <abstract xml:lang="ru">
        <p>Разведка Тырныаузского месторождения, осуществляемая на флан­гах в основном с помощью горно-буровых работ, затрудняется не толь­ко специфическими особенностями высокогорья, но и, главным образом, мощными (от 50 до 180 м) делювиально-моренными отложениями. Эти отложения представлены не связанными между собой обломками изме­ненных пород различной твердости и абразивности: аргиллитов, алевро­литов, туфопесчаников, гранито-гнейсов и роговиков разнообразного состава. Кроме того, на северных склонах хребта распространены участ­ки многолетней мерзлоты, что делает специфику буровых работ близ­кой к условиям Крайнего Севера.</p>

      <abstract xml:lang="en">
        <p>Exploration of the Tyrnyauz deposit, carried out on the flanks mainly by means of mining and drilling operations, is complicated not only by specific features of the highlands, but mainly by thick (from 50 to 180 m) deluvial-moraine deposits. These sediments are represented by unconnected fragments of altered rocks of different hardness and abrasiveness: mudstones, siltstones, tuff-sandstones, granite-gneisses and hornblende of various compositions. In addition, on the northern slopes of the ridge there are widespread areas of permafrost, which makes the specifics of drilling operations close to the conditions of the Far North.</p>
