VMS型矿床受矿业界和学术界高度重视。借助现代洋底发现的黑烟囱，对VMS型矿床海底热液阶段成矿机理的认识已较为成熟。但大部分有工业价值的VMS型矿床都保存在现今造山带内，对其“登陆”后的保存和改造变化关注较少，尤其是其遭受变质变形改造时相关成矿元素的迁移规律研究匮乏。阿尔泰造山带是世界著名的VMS型矿带，阿舍勒铜矿和可可塔勒铅锌矿是该成矿带内具有VMS成矿特征的超大型矿床。本项目拟重点查明两个矿床变质变形条件及其对硫化物富集的控制规律；精细识别从原生海底热液成矿阶段到变质变形阶段的组构和矿物组合；利用LA-ICP-MS技术对上述硫化物及其过渡类型进行原位微区分析；提取用于指示VMS型矿床组分活化再迁移的指标性参数；对比分析富铜型和富铅锌型VMS矿石活化条件和组分迁移规律的异同点。预期成果可阐明VMS型矿床在不同变质变形条件下的元素迁移富集规律，为造山带内改造型VMS矿床的勘查提供科学支撑。

Volcanogenic Massive Sulfide (VMS) deposits provide huge amounts of Cu, Pb and Zn metals, and have therefore drawn high attentions from geoscientists and mining professionals. However, the element remobilization rules of VMS deposits during metamorphism and deformation are poorly understood. Our previous studies had illustrated the Ashele VMS Cu and Keketale VMS Pb-Zn deposits in the southern Altay experienced intense metal remobilization. In this proposal, based on the detailed identification of the ore minerals from the primary seafloor ore-forming stages to the subsequent reworked stages, we systematically analyze the contents and in-situ distributions of trace elements in the above-mentioned sulfides using LA-ICP-MS technique, and try to discover the available parameters that indicate element remobilization of the Ashele and Keketale VMS deposits. We aim to reveal the element remobilization rules of VMS deposits overprinted by metamorphism and deformation, and also to provide guidance to exploration of the metamorphosed VMS deposits in the orogen.
