Mesozoic ore systems were responsible for the formation of numerous Au, Ag, Mo, and Pb occurrences and deposits in the North-Stanovaya
metallogenic zone, the largest of which are the Bamskoe, Vykhodnoe, Mogotinskoe, Dess, Nakhodka, and Apsakan deposits. The
age of the hydrothermal-metasomatic processes that accompanied the mineralization is 130–122 Ma, which allows us to relate
the ore formation to the origin of the granitoids of the Tynda-Bakaran complex (138–124 Ma). The latter rocks form large intrusions
united into the Stanovoi Belt in the southeastern framing of the North-Asian Craton. The ore objects change in the sequence
Au-Ag-Au-Mo(Au) from the south northward and are restricted to the contact zones of intrusions of the Stanovoi Belt, which
were probably formed at the transform continental margin. 相似文献

The results of studying the Mogot silver-base-metal deposit located in the Dzhugdzhur-Stanovoi Superterrane are discussed in this paper. The main ore-controlling structural elements of the studied district are near-latitudinal and NE-trending faults, which are accompanied by zones of hydrothermal metasomatic potassic, propylitic, and argillic alterations, breccias with quartz and quartz-carbonate cement replacing metamorphic rocks and granitoids of the Late Stanovoi Complex. The total sulfide content in ore is 2–3%. The high Ag, Pb, and Zn contents in ore allow us to consider the Mogot deposit as silver-base-metal, since except of orebody 4, there are no silver minerals proper. This indicates that silver is incorporated into crystalline lattice of sulfides. The results of 40Ar/39Ar geochronological investigations show that the hydrothermal ore deposition dated at 127–125 Ma was related to emplacement of intrusions pertaining to the Tynda-Bakaran Complex. 相似文献
