It is shown that xenolith with a size of 8.5 × 4 m is composed of websterite in the central part and plagiowebsterite in the marginal. The chemical and mineral composition of xenolith rocks was studied. Information is given on the contents of noble and chalcophile elements in them, as well as the composition of platinum group minerals.</p></abstract><trans-abstract xml:lang="ru"><p>Представлены результаты исследований глубинного платиноносного ксенолита, обнаруженного в Волчьетундровском габбро-анортозитовом массиве в Кольском регионе. Показано, что ксенолит размером 8,5×4 м сложен вебстеритами в центральной части и плагиовебстеритами в краевой. Изучен химический и минеральный составы пород ксенолита, приведены сведения о содержаниях в них благородных и халькофильных элементов, а также о минеральном составе платинометальной минерализации.</p></trans-abstract><kwd-group xml:lang="en"><kwd>deep xenolith</kwd><kwd>websterite</kwd><kwd>plagiowebsterite</kwd><kwd>chemical composition of rocks</kwd><kwd>the content of noble and chalcophile elements</kwd><kwd>platinum group minerals</kwd><kwd>Volchetundra gabbro-anorthosite massif</kwd><kwd>Kola region</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>глубинный ксенолит</kwd><kwd>вебстериты</kwd><kwd>плагиовебстериты</kwd><kwd>химический состав пород</kwd><kwd>содержание благородных и халькофильных элементов</kwd><kwd>минералы платиновой группы</kwd><kwd>Волчьетундровский габбро-анортозитовый массив</kwd><kwd>Кольский регион.</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="en">Russian Foundation for Basic Research</institution></institution-wrap><institution-wrap><institution xml:lang="ru">Российский фонд фундаментальных исследований</institution></institution-wrap></funding-source><award-id></award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Чащин В.В., Баянова Т.Б., Елизарова И.Р., Серов П.А. // Петрология. 2012.
