Как считается эта оценка

Складывается из проверяемых признаков самой записи: есть ли у статьи DOI, сколько независимых источников подтвердили её данные, заполнены ли обязательные поля и насколько свежо последнее подтверждение. Снижают оценку расхождения между источниками и отсутствие идентификатора. Значение от 80 означает, что запись опубликована без дополнительной проверки; от 60 до 79 — что она опубликована с пониженной достоверностью и ручная проверка желательна. Запись, выверенную редактором вручную, пересчёт не опускает ниже 90. Это оценка наших данных о статье, а не оценка самой статьи.

Аннотация

In the development of high technologies, �lightweight� - rare metals - are of great importance. Almost all modern devices: from a player to an electric bus cannot do without them. These metals are used in mechanical and aircraft manufacturing, digital technologies, and medicine; the implementation of a green program without them is generally impossible. According to statistical forecasts, the need for rare metals will only grow every year. During the Soviet period, most of the rare metal deposits were mined; small ore occurrences were not considered due to low contents and reserves. Currently, the Republic of Kazakhstan has developed a Comprehensive Plan for expanding the resource base and introducing technologies for the integrated extraction of rare metals, modernizing existing production facilities, developing standards regulating the industry and lifting the secrecy regime for individual metals, as well as mining all known ore occurrences and a detailed study of mineralization points. The Kara-Ayak ore occurrence belongs to an unconventional type of rare metal mineralization (Sn, W, Ta, etc.), superimposed on more ancient tectonically prepared intrusions and dikes of the Kunush complex. In the Kalba-Narym zone, similar examples are the already explored and studied greisen-quartz vein deposit Cherdoyak (Sn, W), rare metal-pegmatite objects Medvedka, Tochka, Novo-Saryozek and others (Ta, Nb, Be, Li). The similarity of the geological structure of these objects emphasizes the prospects for assessing the Kara-Ayak ore occurrence.
