| 摘 要： | 胶东大型金矿集中区成矿作用研究的历程可分为勘探初期、区域成矿学发展和大规模成矿作用研究3个阶段。目前已基本确定胶东矿集区的成矿时代是早白垩纪,但进一步精确定年技术和方法的应用仍是今后一段时间内研究的重点;成矿物质来源研究表明,不可能仅仅是“矿源层”或“矿源岩”的贡献,而是壳-幔物质共同参与的结果,壳-幔作用理论研究及进一步证据的取得也是今后一段时间内工作的重点;大地构造背景研究,伴随着我国东部中生代构造事件的研究,认为该区在中生代曾发生过构造体制的重大转折,从而诱发了胶东大规模成矿作用的发生,这一重大事件的时间演化和空间迁移序列,尤其是地球动力学机制仍然不甚清楚,中生代成矿构造事件也是今后进一步探讨的方向。

| Abstract: | The history of study on metallogeny about large gold deposit concentrated area in Jiaodong Peninsula is divided into three stages: the preliminary exploration; development and application of regional metallogeny and the development of Global Large-scale Metallogeny (GLM). The newly study shows that the metallogenic epoch is about in the early Cretaceous period of Mesozoic,but the further precision techniques of chronology in Jiaodong Peninsula will go on and be the focus of mineralization chronology in future. The study of the source of metallogenic substances indicates that mineralization thanks to not only source-bed or source-rock,but crust-mantle interaction.Although the new theory has been put forward,more evidence should be obtained to prove it;the study of geotectonic setting which goes along with the study of geodynamic backgrounds of Mesozoic gold metallogeny in east-northern China reveals that the tectonic system occurred materially transition that induces large-scale metallogeny in Jiaodong Peninsula. But there is some doubt about it, such as how to demarcate the evolvement and interspace transference sequence and "geodynamic mechanism" etc. and these problems should be studied to reveal the Arcanum of metallogeny and tectonic geo-events. |
