中文摘要:壳幔成矿学是联结深部地质学与区域成矿学的重要桥梁。将成矿作用与深部过程联系起来,进行壳幔成矿学研究,已成为当今区域成矿学的一种重要发展趋势。壳幔成矿学研究的核心内容是大陆壳幔多层圈相互作用与成矿关系,而壳幔成矿学研究的主要技术支撑是“岩石探针”分析。壳幔成矿学研究应选择若干典型区域,采用演化历史分析与作用过程鉴别结合的思路,对岩石包体及其寄主岩和有关矿床进行深入研究,以查明区域壳幔相互作用事件幕与成矿作用事件幕及其时空耦合关系,揭示多层位岩浆一热流体系统的演化历史及其对成矿元素富集成矿的制约,提出区域壳幔相互作用与成矿过程模型,为建立新一代成矿学知识体系提供新的思路和科学依据。 |

Abstract:Crust- mantle metallogeny is an important bridge linking deep geology with regional metallogeny. The research of crust-mantle metallogeny through connecting the mineralization with the deep process has become an important trend of regional metallogeny. The key research content of crust- mantle metallogeny seems to be the relationship between continental multilevel crust-mantle interaction and mineralization, and the main technological support for the research of crust-mantle metallogeny is the "petroprobe" analysis. The crust-mantle metallogenic study on the xenoliths as well as their hosts and relevant deposits in several selected typical districts can be carried out through combining the analysis of evolutionary history with the discrimination of action process . This would give a clue to discriminating episodes of crust- mantle interaction and metallogeny as well as their temporal and spatial coupling relation and gain new insights into evolutionary history of multi-level magmatic-hydrothermal systems and their constraint on the enrichment of metallogenic elements for forming ore deposits. On the basis of this study, a model for regional crust- mantle interaction and metallogenic process is advanced, which can provide new thought and scientific evidence for establishing a new generation of metallogenic knowledge system. |
