| 摘 要： | 根据对围山城金银成矿带的成矿元素、黄铁矿微量元素标型特征、成矿流体地球化学特征、稀土元素、硫铅同位素和氢氧同位素特征的研究,提出矿带中的初始成矿物质主要来源下地壳和上地幔,由海底火山喷流作用形成。各工业矿体的形成与后期叠加构造和热流体的改造作用密切相关。

| Abstract: | According to the study of the ore-forming elements,typical characteristics of pyrite micro elements,geochemical characteristics of the ore-forming fluid,rare earth elements,sulfur-lead isotopes and hydrogen-oxygen isotopes in the Weishancheng metallogenetic belt,it is concluded that the source of primary ore-forming materials was from lower crust and upper mantle,and formed by submarine volcanic eruption.The formation of economic ore bodies is closely related to the structures superimposed later and the thermal fluid reformation.The infiltration and enrichment of the underground thermal brine in the later deep cycle is crucial to the formation of the economic ore bodies. |
