从全球范围看,迄今发现和初步鉴定的数十个山字型构造体系,主要分布于北半球, 其中尤以亚洲大陆居多和研究较详(仅我国境内已基本肯定的山字型构造就达20个以上)。因此,探讨亚洲地区已知山字型构造的空间排列规律和组合特征,对于剖析陆壳构造运动的方式与方向,扩展普查找矿和勘探领域等方面,都有不容忽视的理论和现实意义。 Globally, dozens of mountain type structural systems discovered and tentatively identified so far are mainly distributed in the northern hemisphere, with the majority being in Asia and the more detailed in the study (only the mountain-shaped structures that have been basically affirmed in our country have reached 20 More than one). Therefore, it is of great theoretical and practical significance to explore the spatial arrangement and combination features of known mountain-shaped structures in Asia for analyzing the ways and directions of continental crustal movement and expanding areas of census prospecting and prospecting.
