| 中文摘要:成矿系统是在一定时空域中由控制成矿诸要素结合成的、具有成矿功能的统一整体，它包括成矿物质由分散到富集的制约因素、作用过程及各种地质矿化产物，成矿系统是成矿带、矿集区找矿预测研究的理论基础。矿集区的成矿系统研究主要是在对矿集区矿化类型精细厘定基础上，进一步研究成矿系统的源、运、储，以及成矿期后抬升剥蚀与改造，构建成矿系统模型。文章从成矿系统理论角度出发，系统讨论了热液类重要金属矿床的成矿系统构成与特征，指出热液类重要金属矿床的成矿系统主要由矿源体、成矿构造系统和矿化-蚀变系统构成；并从找矿预测方法与研究内容考虑，对热液类重要金属矿床按岩浆热液类、热液脉型金矿类和层控类3大类矿床进行了成矿系统研究与找矿预测分析。提出了岩浆热液类矿床的找矿预测主要是围绕成矿岩体开展工作，热液脉型金矿的找矿预测工作的核心是成矿构造研究，层控类矿床找矿预测核心是层位+通道找矿。矿集区找矿预测是在基本探明已知矿床基础上的矿山深边部和外围找矿，找矿方向主要是新延伸、新区段、新中心、新系统（简称“四新”），对应的成矿系统研究为子系统、单系统、多系统和新系统找矿4个方面。以斑岩铜多金属成矿系统、中高温岩浆热液型钨锡-多金属成矿系统、造山型金矿成矿系统、VMS型成矿系统、砂岩型矿床成矿系统为例，讨论了它们各自的成矿系统组成、特征，以及相应的“四新”找矿预测工作内容和方法。 |

| Abstract:The mineral system is a unified whole with metallogenic function, which is composed of various factors controlling mineralization in a certain time and space. It includes the restrictive factors, action processes and various geological mineralization products of ore-forming materials from dispersion to enrichment. The mineral system is the theoretical basis for the study of metallogenic belts and ore-concentrated areas. The study of the mineral system in ore-concentrated areas is mainly based on the fine determination of mineralization types in ore-concentrated areas, and further studies the ore-forming elements of the mineral system, as well as uplift, denudation and transformation after the metallogenic period, and constructs a mineral system model. The composition and characteristics of the mineral system of hydrothermal deposits are discussed in this paper, and it is pointed out that the mineral system of hydrothermal deposits is mainly composed of ore source body, ore-forming structural system and mineralization alteration sub-system. Considering the method of prospecting prediction, the mineral systems of hydrothermal deposits may be analyzed as three types, including magmatic hydrothermal type, hydrothermal vein type (gold deposit) and stratabound type as follows. Ore-forming rock bodies should be the main research object for prospecting and prediction of magmatic hydrothermal deposits; the key to vein gold deposits is the study of ore-forming structure, and the core of stratabound deposits is the study of horizon + channel. Ore-prospecting prediction in ore concentration area is based on the known ore deposits, and the prospecting direction is mainly new extension, new section, new center and new system (referred to as “Four New” for short). The corresponding study of mineral system is in four aspects: subsystem, single system, multi-system and new system. Taking porphyry copper polymetallic mineral system, medium-high temperature magmatic hydrothermal tungsten-tin polymetallic mineral system, orogenic gold mineral system, VMS mineral system and sandstone mineral system as examples, this paper discusses the constitution and characteristics of their respective mineral systems and the corresponding “Four New” prospecting prediction contents and methods. |
