【摘要】 成矿系统是指在一定的时空域中,控制矿床形成和保存的全部地质要素和成矿作用动力过程,以及所形成的矿床系列、异常系列构成的整体,是具有成矿功能的一个自然系统。成矿动力学,是指在一定的地质构造背景下,研究矿床分布规律、形成过程和作用机理的学科。具体而言,是从构造背景、成矿空间、成矿演化、矿质散聚、深部作用和成矿环境等角度探讨挤压、引张和剪切动力作用下的成矿系统、成矿序列、矿化类型、矿化特征和成矿机理。通过探讨研究区铜镍金成矿系统及其成矿动力学,可以从整体上了解该地区的成矿作用,各个成矿要素互相的影响,确定成矿构造背景、成矿流体、动力过程和产物等的整体变化过程。使矿床的研究从静态到动态、单个矿床到系列矿床、从定性到定量,从多方面搞清成矿要素的相互影响、整体演化对成矿作用的控制,从而逐步缩小靶区,找出缺位的矿床或类型。本文以东天山哈密地区铜镍金矿床为研究对象,以研究区的成矿系统和成矿动力学为研究方向,在系统收集、整理东天山以往区域地质调查、矿床勘探与科学研究资料的基础上,对区内成矿地质、地球物理、地球化学条件进行了综合分析,对金、铜、铜-镍的成矿系统进行了初步的划分探讨,总结了大量前人研究的基础上,在考虑铜镍金矿成矿类型、矿床成因、矿化组合以及赋矿地层和含矿建造的基础上将东天山哈密地区的铜镍金矿床成矿系统主要划分为岩浆岩成矿系统、金成矿系统、铜多金属成矿系统和铜-镍成矿系统几个系统类型,同时又将各个成矿系统划分为几个相应的子系统类型并进行了典型矿床的研究;成矿动力学主要包括构造动力成矿作用、岩浆动力成矿作用、变质动力成矿作用、沉积动力成矿作用,本文主要从构造动力成矿作用这一方面入手对研究区成矿动力学进行了相关的探讨。在以上基础上总结出时-空上东天山哈密地区的金铜镍成矿规律,包括区域构造、区域岩浆、区域地层、区域变质作用与成矿的关系。更多还原

【Abstract】 Metallogenic system refers to in the certain space-time domain, which control the formation and save all geological elements and mineralization dynamic process of the deposit, and the deposits series, abnormal series composition as a whole,it is a natural system with metallogenic function. Metallogenic dynamics, it is a subject point to in certain geological tectonic background, which study on ore deposit distribution mechanism, the formation process and the disciplines. Specifically, it is a discussion of metallogenic system, metallogenic series, mineralization type, mineralization characteristic and mineralization mechanism in extrusion, tensile and shear force with the metallogenic tectonic background, metallogenic space, metallogenic evolution, mineral scattered gathers, the deep effect and metallogenic environment aspects discuss ofWith he discussion of Metallogenic system and Metallogenic dynamics Copper-Nickel-Gold of Hami,we can understand the mineralization in this region and the influence of different metallogenic element each other,to make sure the overall change of the metallotectonic background, metallogenic fluid, dynamic process and products.To make the research of deposit from static to dynamic,from single deposit to series deposits and from qualitative to quantitative ,and to find out the interaction between metallogenic elemets and the overall evolution of the mineralization controls, thus gradually narrowing target area, find out the deposit or absence types.This paper makes Copper-nickel-gold deposits of Hami as the research object,and makes Metallogenic system and Metallogenic dynamics as the research direction,on the basis of systematic collection the previous regional geological survey, ore exploration and scientific research date of East Tianshan, comprehensive analysis the geological,geophysical and geochemical conditions of this ragion.Gave a preliminary classification of the metallogenic system of the Copper-Nickel-Gold deposits.Summarized on the basis of a large number of previous studies, in considering the type, genesis, composition and ore mineralization and ore-bearing formation of Copper-Nickel-Gold deposits,the main metallogenic of Copper-Nickel-Gold deposits of system of Hami region is divided into magmatic system and gold metallogenic system, copper and copper polymetallic metallogenic system and Copper-Nickel metallogenic system, in the same time everyone will also be divided into several different sub-metallogenic system and do some research of the typical deposits. The Metallogenic dynamics include tectonic mineralization, magma motive power mineralization, metamorphic dynamic mineralization, sedimentary dynamic ore-forming processes, in this paper we will disscuss the Metallogenic dynamics in tectonic mineralization aspect. On the basis of the above research ,thia paper gave a summary of the Copper-Nickel-Gold mineralization law of Hami of East Tianshan in time-space, including the relationship between regional tectonics, regional magma, regional strata, regional metamorphism and metallogenic.更多还原
