| 摘 要： | 文章在燕山地区找矿实践中,应用矿床的成矿系列概念和分析方法开展了成矿预测研究,提出了成矿系列缺位概念,其含义是指在一定的区域内,依据矿床的成矿系列概念,经对该区地质演化历史、矿床形成地质环境、成矿作用、成矿物质、矿床时空分布规律、成矿系列模式、成矿体系的系统研究后,确定的成矿体系中各个序次的成矿系列在空间、时代、矿床类型、成矿元素(矿种)等方面应当存在而尚未被发现的部分。并把成矿系列缺位分出4个类别,即成矿系列空间缺位、成矿系列时代缺位、矿床类型缺位、矿床成矿元素(矿种)缺位。对运用成矿系列缺位概念进行成矿预测时应重点研究的内容进行了初步探讨,列举了成矿系列缺位预测成功范例。

| Abstract: | According to metallogenic prognosis researches of the application of the concept and analytical method of the metallogenic series of ore deposits based on ore prospecting practice in the Yanshan Mountain area, this paper puts forward the concept of location-vacancy of metallogenic series. This concept means that we can determine the parts which ought to be existent but has not been detected, such as earth space, metallogenic epoch, deposit type and ore-forming elements in every metallogenic series of the ore-forming system in a definite region. This is based on a systematic study of such factors as geological evolution history, geological environment of ore formation, ore-forming process, ore-forming material, space-time distribution regularity of ore deposits, metallogenic series models and ore-forming system in the light of the concept of metallogenic series. The authors divided the location-vacancy of metallogenic series into four types, namely, location-vacancy of metallogenic series on earth space, location-vacancy of metallogenic series on metallogenic epoch,location-vacancy of metallogenic series on deposit type, and location-vacancy of metallogenic series on ore-forming elements. When making metallogenic prognosis based on the concept of location-vacancy of metallogenic series, we should emphatically study geological evolution history, every kind of geological incidents, geological environment for ore formation, minerogenic and controlling factors, tectonic features, geophysical and geochemical conditions, the division of metallogenic series, the formation of ore deposits, and the construction of the ore-forming system. Having successfully applied the location-vacancy of metallogenic series, the authors discovered two large-size ore deposits and two medium-size ore deposits in the prognostic area. |
