中文摘要:
      [摘要]本文在分析中国区域地质特征的基础上,以ETM 卫星影像为信息源,依据地质学家李四 光确定地块的原则和地壳运动规律,根据ETM 影像的色调、影纹和地貌等特征,建立了地块划分准则, 以此为依据将中国大陆划分成28 个大地块,编制了中国大陆地块盆地分布图。本文在分析地壳运动规 律和各地块的运动特征的基础上,提出了各地块之间进行着规律性的相互推挤运动,且北部地块向南推 移和就位,西部地块向东推移和就位的新观点。本文通过分析已知大中型金属矿床的统计分布规律:大 部分矿床分布在地块东、南侧,地块运动方向的前锋,尤其是弧形拼合带前缘;提出了在块体碰撞带或块 内大构造带南找大矿的新思路。
英文摘要:
      Abstract:Based on tectonic features and ETM satellite images,following the idea of the geologist Li Siguang,we attempt to establish a new principle of massive division for China mainland. Then the Chinese mainland is subdivided into 28 first-order massifs,and a map of massifs and basins across the mainland is compiled. We suggest that mutual push and relative motions are undergoing between these blocks,with a general pattern that the massifs in the north are moving toward south and those in the west are drifting to the east. Statistics indicates that most of the large- and intermediate-sized metal deposits are located on the eastern and southern sides of blocks,which are the fronts of moving massifs,especially the leading edges of the curved sutures. Finally,we proposes to search for large metal deposits in sutures between massifs or major structures within massifs.
