文摘 课题拟重点开展华北北缘及其邻区燕山期岩浆-成矿作用的时空分布规律、成岩-成矿性质及形成背景研究。通过对比不同时空背景下岩浆-成矿作用的类型,查找典型构造带上岩浆的岩石化学及同位素组成的时空演变规律,明确古鄂霍茨克洋和太平洋俯冲体系对区内岩浆作用的制约,限定古洋壳向华北地块俯冲、转换的时限。分析岩浆-金属成矿作用区岩浆产生的物理化学条件、运移演化过程、源区性质及记录的壳幔相互作用,并在剖析典型资源矿产聚集区燕山期成矿类型及成矿机理基础上,探讨岩浆性质、成岩过程与成矿类型、成矿作用的关系,建立岩浆-成矿作用与古洋壳俯冲叠合的内在联系,构建成岩-成矿作用与块体俯冲拼合的动力学过程。同时,将深源岩石包体示踪和地球物理资料有机结合,开展不同地区深部岩石圈组成、结构,以及深部过程与浅部响应的综合研究。
其他语种文摘 This project plans to mainly focus on the temporal and spatial distribution,nature and types,geological background of the Yanshanian magmatism and metallogenesis in the northern North China Craton (NCC) and its adjacent regions. Based on comparisons of the types of the magmatism and metallogenesis that formed in different ages and tectonic regimes, the project will try to find out the possible changing trends within the petro-geochemistry and isotopic composition of the Yanshanian magmas that occurred at some main tectonic belts,so as to clarify the possible relationship between the ancient Okhotsk and the Pacific subduction system and the Yanshanian magmatism,and constrain the accurate time of tectonic transition from the paleo-Okhotsk to the Pacific subduction system. Meanwhile,we will also discuss the physical and chemical conditions required for the magma generation,evolution and source composition of the magma,and the crustmantle interaction recorded in the magma; and these,in combination with the interpretation of the types and mechanism of the Yanshanian deposits,will be used to decipher the characteristics of the magma,the relationship between the magmatism and metallogenesis. All these above will enable us to identify the internal links between the magmatism-mineralization and the subduction of paleo-oceanic crust,and establish the geodynamic processes of the Yanshanian magmatism and metallogenesis that involved with the subduction and convergence of the paleo-oceanic crust. On the other hand,combine the available geophysical data and studies of the deep-seated xenoliths,the project will further reveal the nature,composition and structure of the deep lithosphere in the study areas,as well as the links between deep process and shallow response.
