【摘要】 矿床成矿系列是研究成矿作用在四维空间中的规律，探索在地球发展过程中成矿的时空、物质的演化及其分布规律；研究矿床成矿系列可以提高人们对全球地质规律的认识，并且有效地指导找矿预测工作，促进矿产资源勘查工作的开展。本文立足于东天山地区铜及其多金属矿床的野外地质调查研究，从充分整理和吸收消化前人大量研究成果的基础之上，选择重点矿床进行解剖，辅以岩石学和高精度同位素年代学研究，尝试应用成矿系列理论来认识东天山地区铜矿床的时空分布和演化谱系，以内生金属矿床时空分布样式作为大地构造环境的标志和限定，为东天山大型铜矿富集区的战略靶区优选提供理论依据。 1、按照成矿系列理论的学术指导思想，将研究区华里西期铜矿床成矿系列划分为四个成矿系列亚系列： Ⅰ、晚泥盆—早石炭世延东—土屋—三岔口与中酸性岩浆侵入活动有关的Cu、Mo、Au矿床成矿亚系列 Ⅱ、早石炭世与岩浆作用有关的铁、铜、金、银矿床成矿亚系列 Ⅲ、中石炭世与岩浆作用有关的Cu、Fe、Ag、Au矿床成矿亚系列 Ⅳ、晚石炭世-早二叠世与幔源基性—超基性岩有关的铜、镍、铂族矿床成矿亚系列 并从地层、岩浆岩、控矿构造、地球化学、成矿特征等方面对各成矿亚系列进行了详细论述。 2、在充分考虑成矿时间的统一性和时序的演化性、区域地质构造演化与区域成矿演化关系，结合地质、构造、地球物理、地球化学、遥感资料，对研究区进行了成矿区带划分，共划分了两个Ⅱ级成矿区(准噶尔成矿区和塔里木成矿区)利四个Ⅲ级成矿带(哈尔里克Cu、NI、Au、Zn、Mo成矿带、吐鲁番—哈密盆地(油气、煤、盐)成矿区(带)、觉罗塔格Au、Cu、(Fe)成矿带和卡瓦布拉克—星星峡Au、Pb、Zn、Sn、Fe成矿带)； 3、对研究区内不同成矿系列的典型矿床进行了解剖，详细研究了土屋、雅满苏、小热泉子、维权、黑尖山、黄山和黄山东各典型矿床的成矿区域地质构造背景、矿床地质、同位素、微量元素、稀土元素、包裹体测温等内容；查明了矿床之间的差异性和内在联系。 4、Re-Os同位素是一种十分有效的成岩成矿示踪体系，而且很少受到成矿后地质事件的干扰；应用Re-Os同位素对黄山东铜镍硫化物矿石进行精确定年，对追索该矿床成岩成 中国地质人学（北京）博士：论义矿物质来源和壳慢混染程度，深化成矿作用和成矿过程的研究，而且有助于深刻认识成矿的地球动力学环境。此外，铜镍硫化物以及相关岩体往往形成于拉张环境、大陆边缘伸展环境或与地帼柱活动有关，对其精确测年和动力学环境研究有助于对东大山地球演化历史的深入了解。 5、根据区域成矿作用的演化历史与矿产分布规律，探讨了东大山地区海的期成矿规律，论述了研究厂成矿亚系列主要成矿元素演化轨迹，建立了海的期铜成矿演化谱系，认为研究区海的期成矿作用具有突变特征一人爆发成矿作用特点。更多还原

【Abstract】 1, Regional ore-forming geological settingThe east Tianshan strides across three large plates. The Siberian plate crosses in the northern edge of the studied area, where as the Kazakhstan-Zhungaer plate and Tarim plate connect with each other in the south of the area through the Kangguertage-Huangshan fault. On the basis of the an integrated study on strata, magmatic-volcanic activities, geochemistry as well as geophysics and remote sensing imagines, three subtectonic units were divided.2 , Metallogenic series of copper depositsWith the elapse of time, the tectonic-magmatic evolution went on from south to north ,which resulted in regular production and spatial distribution of ore resources, correspondingly forming east Tianshan copper, gold, nickel, iron, silver clucters of mineral deposits.In the light of the concept of metallogenic series by Cheng Yuqi,Chen Yuchuan et al., the copper, iron , nickel and silver deposits might be assigned to four metallogenic series:I .The metallogenic subseries of copper, molybdenum, gold, silver deposit related to late Devonian-early Carboniferous basic-intermediate-acid hypabyssal intrusive-eruptive rocks;II. The metallogenic subseriesof iron, copper, zinc deposits related to early Carboniferous basic-intermediate-acid volcanic-intrusive rocks;III.The metallogenic subseries of copper, silver , iron deposits related to Middle -late Carboniferous basic-intermediate-acid volcanic-intrusive rocks;IV. The metallogenic subseries of copper, nickel and platinum group deposits related to Late Carboniferous-Early Permian basic-ultrabasic rocks;3, Division of regional major metallogenic beltsOn the basis of the previous work conducted and by following the principles, grounds and methods of the division of metallogenic belts, areas and fields,.In light of this , metallogenic belts of grade IV were Divided . Such a division may better reflect the minerals distribution and formation laws, more accurately guide prospecting .4, Research on model copper depositsThe copper deposits related to intermediate-acidic volcanic-intrusive complexes are widespread in eastern Tianshan. They can be divided into these types: (1) porphyry type; (2) skarn type;(3)volcanic type;(4)copper-nickel sulphide type .更多还原
