    • 摘要: 20世纪90年代以来,火山机构控矿理论在海相火山岩区块状硫化物矿床研究中得到了越来越多的关注,基于该理论的指导,在北祁连山东段的白银矿田取得了找矿突破性进展。其间,详细的海相火山岩相地质填图工作为白银矿田火山机构与成矿联系的研究及找矿突破奠定了坚实的基础。反映出在海相火山岩区推行合理可行的火山岩相地质填图方法至关重要。以白银矿田海相火山岩区为例,首先,对该区大比例尺火山岩相填图及古火山机构厘定成果进行介绍;其次,通过分析、借鉴此成功案例,总结海相火山岩区填图内容和技术方法;最后,阐述应用该方法在北祁连山中段祁连县一带海相火山岩区进行大比例尺填图的成功尝试。

       

      Abstract: Since the end of the 1990s, the theory that paleovolcanic apparatus can dominate massive sulfide deposit in marine volcanic terrain has attracted more and more attention. Based on this theory, great progress for mineral exploration has been made in the Baiyin orefield located in the eastern part of the North Qilian Mountain. Meanwhile, exploration of the mapping method based on volcanic rock facies has laid the foundation for recognizing the paleovolcanic edifices and mineral exploration. Thus, it should be very important to employ reasonable methods for mapping in the marine volcanic terrain. In this paper, firstly the authors analyzed the paleovolcanic apparatus of the Baiyin orefield and introduced the achievement of large-scale mapping. Then, based on an analysis of the successful case, the authors summed up the contents and methods for mapping in the marine volcanic terrain. At last, guided by the method, the authors provided two successful examples of mapping work in the region near the Qilian County, which is located in the middle part of the North Qilian Mountain.
