      <abstract xml:lang="ru">
        <p>Оценено содержание благородных металлов и рения в черных сланцах нижнего палеозоя восточной части Прибалтийского палеобассейна на территории России. Сланцы обогащены платиноидами (МПГ до 0,12 г/т) и рением (до 1,54 г/т). Основными элементами-спутниками благородных металлов и Re являются U, V, Mo, Cu, Ni. Черные сланцы состоят из органической (9-26 отн.%), глинистой (40-60 отн.%), алевро-песчаной (25-50 отн.%) составляющих и конкреционного комплекса (2-5 отн.%) (карбонатные, сульфидные, фосфатные и силикатные конкреции). Благородные металлы спорадически встречаются в составе алевро-песчаной примеси в виде самородных форм и интерметаллидов: Auсам, Au-Ag, Au-Cu, Au-(Cu)-Hg, Au-Hg, Ag-Cu, Pt-Fe. В составе диагенетических сульфидов выявлены микроминеральные фазы благородных металлов: Auсам, халькопирит с примесью Au, пирит с примесью платиноидов. Глинистая фракция обогащена благородными металлами в 10 раз больше по сравнению со сланцем – до 0,28 г/т Au, 0,55 г/т Pt, 1,05 г/т Pd, 1,56 г/т Re. Органическое вещество ограничено сорбирует благородные металлы, но накапливает рений. Поровое пространство черных сланцев содержит коллоидно-солевую составляющую (субмикронную фракцию), которая представлена частицами размером менее 1000 нм. Доля субмикронной фракции черных сланцев составляет 0,1-6 вес.%. В субмикронной фракции содержится в среднем: МПГ – 14 г/т, Au – 0,85 г/т, Re – 4,62 г/т. Оценен геохимический ресурс благородных металлов (Au, Pt, Pd), Re и элементов-спутников (U, V, Mo, Cu и Ni) для черных сланцев в целом и их субмикронной фракции. Черные сланцы рекомендуются в качестве комплексного источника сырья.</p>

      <abstract xml:lang="en">
        <p>The content of noble metals and rhenium in the Lower Paleozoic black shales of the eastern Baltic paleobasin in Russia was estimated. Shales are enriched in platinoids (PGM to 0.12 g/t) and rhenium (to 1.54 g/t). The main accessory elements of noble metals and Re are U, V, Mo, Cu, and Ni. Black shales consist of organic (9-26 rel.%), clay (40-60 rel.%), and silt-sandy (25-50 rel.%) components and a nodule complex (2-5 rel.%) (carbonate, sulfide, phosphate and silicate nodules). Noble metals occur sporadically in the silt-sandy admixture as native forms and intermetallics: Aunat, Au-Ag, Au-Cu, Au-(Cu)-Hg, Au-Hg, Ag-Cu, Pt-Fe. Micromineral phases of noble metals were found in diagenetic sulfides: Aunat, chalcopyrite with Au admixture, pyrite with platinoid admixture. Clay fraction is 10-fold enriched in noble metals as compared to shale – to 0.28 g/t Au, 0.55 g/t Pt, 1.05 g/t Pd, and 1.56 g/t Re. Organic matter sorbs noble metals to a limited extent but accumulates rhenium. Pore space of black shales contains a colloidal salt component (submicron fraction) which is represented by particles smaller than 1,000 nm. The share of submicron fraction in black shales is 0.1-6 wt.%. The submicron fraction contains on average: PGM – 14 g/t, Au – 0.85 g/t, and Re – 4.62 g/t. The geochemical resource of noble metals (Au, Pt, Pd), Re and the accessory elements (U, V, Mo, Cu, and Ni) for black shales as a whole and their submicron fraction was estimated. Black shales are recommended as an integrated source of raw materials.</p>
