| 摘 要： | 金、铜、铅、锌(银)矿是辽宁地区的优势矿种，过去和现在都曾从多个不同角度或多个方面予以研究论述，但从成矿系列理论研究则是作者(1994)在Ⅱ轮区划工作中所做的一种新的尝试。根据程裕淇先生的成矿系列理论，辽宁地区早前寒武纪变质岩系中的金、铜、铅、锌(银)矿床属变质成矿系列组合，可进一步划分为三个成矿系列，六个成矿亚系列，九个矿床(种)类型和十二个矿床式。成矿系列特征表明成矿物质与原岩的含矿性关系非常密切，成矿物质或元素具有随原岩建造时空演化而演化的特点，成矿具有鲜明的专属性和层控性，是典型或比较典型的层控变质矿床。金矿床的形成和分布均与韧性剪切带及其糜棱岩有关，表明辽宁前寒武纪金矿床的形成不仅与变质作用有关，而且韧性剪切作用也是极其重要的成矿条件；铜、锌(银)和铅、锌(银)矿床以块状硫化物型为主，其成矿多与火山作用关系十分密切，变质作用过程中，发生重就位或再富集，或热液交代富集成矿。由太古宙至早元古代不同成矿系列或成矿亚系列中的矿床具有自下而上有序的空间分布规律。

| Abstract: | Au, Cu, Pb, Zn (Ag) ore, the superior kinds of ore in Liaoning, have beenstudied and discussed in the past and now from various different sides. To study its metallogenic serious is a new way that was tried by the author (1944) during the second regional programme of metallogenic prospect. According to the Cheng Yuqi's theory of metallogenic serious, Au Cu PbZn (Ag) deposits, from Early Precambrian metamorphic rocks in Liaoning area, belong tometallogenic serious association of metamorphic ore deopit. They are devided into threemetallyenic serious, six metallogenic subserious, nine types of ore deposit, twelve models of ore deposit. Features of metallogenic serious indicate that metallogenic substances are closely relatedto the propertes of their protolith. Metallogenic substances or elements evolve with the evolutionof the protolithic assemblages in time and space. Metallogenesis has metallogenic specializationand layer-bound property. It is typical layer-bound metamorphic ore deposits. The formation anddistribution of gold deopits are related to ductile shear zones and mylonites. Which indicates thatthe formation of Precambrian gold deposits in Liaoning is related to not only metamorphosis, butalso ductile shearing belt. Main type of Cu-Zn and Pb-Zn-(Ag) ore deposits are massive sulphidedeposits, and the formation of ore deposits are mainly relatred to volcanism, and during themetamorphic process, ore deposits took their place again, re-accumulated or formed new ore deposits. Ore deopits from different metallogenic serious or metallogenic sub-serious of Archean and Paleoproterozoic distribute regularly in the place from bottom to top. |
