| 摘 要： | 成矿系统是复杂地球巨系统的有机组成部分,其形成分布受地球系统演化的控制。地球历史演化的不同时期发育不同成矿系统,这些成矿系统既是地球系统演化的产物,也在一定程度上记录了地球系统的演化进程。我国地处古亚洲、特提斯—喜马拉雅和环太平洋成矿域的结合部位,构造演化历史十分复杂,成矿系统的叠加复合作用明显,是我国区域成矿的一个特色。成矿系统的空间分布受控于地球动力学的不均一性,以古陆边缘为例,离散型、会聚型、转换型3类构造动力环境各有其特定的成矿系统。成矿系统的形成深度、演变及现存深度取决于所在构造环境的演变。采用构造层含矿性分析法可预估一个区域中的可能矿床类型及其潜力。论文提出了隐伏矿带的概念,将找寻隐伏矿床扩展为找寻隐伏矿带,拓宽了深部找矿思路,是区域成矿学及找矿学的一个进展。

| Abstract: | Metallogenic systems are an important component of the mega-earth system.Their formation and distribution are controlled by the evolution of the earth system.Different metallogenic systems formed at different stages of the geological history are the products of earth system evolution.These systems also document the evolutional processes of the earth to a certain extent.As located in the junction of three tectonic metallogenic domains such as the Palaeo-Asia,the Tethys-Himalaya and the circum-Pacific plates,the China continent underwent very complex tectonic evolutional processes.So the superimposition between metallogenic systems is obvious in China.This constitutes one of main regional metallogenic features of China.Spatial distribution of metallogenic systems is controlled by the unevenness of dynamics of the earth system.For example,different metallogenic systems occurred in divergent,convergent,and transformational tectonic regimes in palaeocontinental margins.Ore-forming depth,evolution and preservation depth of a metallogenic system depend on the evolution of tectonic setting.Analysis of ore-bearing probability of structural layers is an effective way to estimate probable ore deposit types and mineral resource potential in a region.The concept of concealed ore belt,which is put forward in this paper,will enlarge prospecting target from concealed ore deposit to concealed ore belt.Therefore it constitutes an important progress of regional metallogeny and mineral exploration. |
