Gold mineralization is spatially associated with banded ferruginous quartzite, representing one of the most ancient manifestations of gold ore. The Precambrian rocks are combined into deposits complex of the Neoproterozoic Pan-African megacycle of the territory development. Banded iron-silicate rocks occur in sedimentary-volcanogenic rocks that were formed in the subduction trough zones, and are represented by metamorphosed ferruginous quartzites, jaspilites and schists. FSF show tectonic dislocations, shear cracks, and fracture cracks made by gold-quartz-sulphide mineralization. Promising for the identification of gold-bearing mineralization in the rocks of the FSF can be iron-silicate deposits with the occurrence of epigenetic hydrothermal activity as a result of activation of the submarine volcanism of the tholeiitic type.</p></abstract><trans-abstract xml:lang="ru"><p>Железисто-кремнистые формации (ЖКФ) приурочены к докембрийскому фундаменту Аравийско-Нубийского щита в пределах центральной части Восточной пустыни Египта. С полосчатыми железистыми кварцитами пространственно связана золотая минерализация, представляющая одну из самых древних проявлений золотой руды. Породы докембрия объединены в комплекс отложений неопротерозойского панафриканского мегацикла развития территории. Полосчатые железокремнистые породы залегают в осадочно-вулканогенных породах, которые формировались в троговых зонах субдукции, и представлены метаморфизованными железистыми кварцитами, джеспилитами и сланцами. В породах ЖКФ проявлены тектонические дислокации, трещины сдвига и трещины отрыва, выполненные золото-кварц-сульфидной минерализацией. Состав пород ЖКФ определяется присутствием двух главных минералов: кварца и гематита. Перспективными на выявление золотосодержащей минерализации в породах ЖКФ могут быть железистые кварциты с проявлением продуктов эпигенгетической гидротермальной деятельности в результате активизации субмаринного вулканизма толеитового типа.</p></trans-abstract><kwd-group xml:lang="en"><kwd>banded ferruginous-siliceous formation</kwd><kwd>Eastern Desert of Egypt</kwd><kwd>Arabian-Nubian Shield</kwd><kwd>Kursk Magnetic Anomaly</kwd><kwd>gold mineralization</kwd><kwd>Neoproterozoic</kwd><kwd>volcanogenic-sedimentary rocks</kwd><kwd>gold-quartzsulphide type of ore</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>полосчатые железокремнистые формации</kwd><kwd>Восточная пустыня Египта</kwd><kwd>Аравийско-Нубийский щит</kwd><kwd>Курская магнитная аномалия</kwd><kwd>золотая минерализация</kwd><kwd>неопротерозой</kwd><kwd>вулканогенноосадочные отложения</kwd><kwd>золото-кварцcульфидный тип руды</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Li ZQ, Zhang LC, Xue CJ, Zheng MT, Zhu MT, Robbins LJ, Slack JF, Planavsky NJ, Konhauser KO.
