辽宁东部鞍山群和辽河群的老变质岩系分布很广,但对其地质构造特点论述不多。现在,在这些老变质岩系中,已知层控矿床、矿点、矿化现象有几百处,其中绝大多数应认为被一定的构造控制着。分析辽东老变质岩系的构造特点,认识构造与层控矿床的关系,对成矿予测工作有很大意义。 近几年来,我们结合科研工作,零星地收集和比较系统地阅读了一部分有关资料,感到有些问题,需要抛砖引玉。
The old metamorphic rocks of Anshan Group and Liaohe Group in eastern Liaoning are widely distributed, but their characteristics of geological structure are not discussed much. Now, in these old metamorphic series, there are hundreds of known deposit, mineralization and mineralization, most of which should be considered as controlled by a certain structure. It is of great significance to analyze the tectonic characteristics of the old metamorphic rocks in Liaodong and to understand the relationship between tectonics and stratabound mineral deposits. In recent years, we have combined some scientific research work with sporadically collecting and systematically reading some of the relevant information. We feel there are some problems that we need to start with.
