Abstract
This article considers the mineralogical and geochemical features of the Early Cretaceous gold ore deposits in the Northern Okhotsk region, that is, the southeastern flank of the Yana-Kolyma orogenic belt and the Okhotsk sector of the Okhotsk–Koryak orogenic belt. Dating results are reviewed and the general and distinctive geological, mineralogical, and geochemical features of different mineralization types are shown. A close genetic link of ore mineralization with Early Cretaceous magmatism and formation of the Uda-Murgal magmatic arc is assumed.
期刊介绍：
Russian Journal of Pacific Geology publishes the results of research on the Earth crust and mantle composition and provides articles on the geological structure and patterns of distribution of mineral deposits in the Pacific Ocean, marginal seas and continental margins. It discusses the topics of stratigraphy, sedimentology, magmatic activity, and seismicity. The journal deals with the problems of lithosphere plates tectonics, and offers the results of neotectonic, geomorphological, geodesic, environmental and mining studies in the Pacific region. The journal accepts theoretical, methodical and philosophical articles covering general issues of geology, geophysics, geochemistry, geoecology and mining. The journal also publishes critical notes and comments, and reviews.
