Abstract

A structural interpretation of the first Re–Os dating of pyrite and arsenopyrite from the Malinovsky gold deposit is given. Comparison of the obtained data and the known ages of ore-bearing granitoids from the ore field made it possible to determine the age of mineralization as 100–90 Ma. This age corresponds to the time of completion of the Albian–Cenomanian geodynamic setting of the transform margin of the Asian Continent with significant left-shear dislocations, as is evident from the structural patterns of localization of ore bodies and magmatic rocks. The time interval and geodynamic conditions for the formation of the Malinovka deposit are similar to those of many gold and gold-bearing deposits within the Sikhote-Alin orogenic belt and the south of the Korean Peninsula.

俄罗斯锡霍特-阿林金矿区 Malinovka 矿床金矿化形成的时代和地球动力学因素

摘要

给出了对来自 Malinovsky 金矿床的黄铁矿和毒砂的第一次 Re-Os 测年的结构解释。将获得的数据与矿场含矿花岗岩的已知年龄进行比较，可以确定成矿年龄为 100-90 Ma。从矿体和岩浆岩定位的结构模式可以明显看出，这一时代对应于亚洲大陆转换边缘阿尔比-塞诺曼阶地球动力学背景的完成时间，具有显着的左剪切位错。Malinovka 矿床形成的时间间隔和地球动力学条件与锡霍特-阿林造山带和朝鲜半岛南部的许多金和含金矿床相似。
