摘　　要：河南省大地构造单元涉及华北陆块、秦岭造山带和扬子陆块。前中侏罗世华北陆块区的大地构造单元划分在省内外基本上形成了共识,而有关秦岭造山带构造单元的划分存在较大分歧,许多岩石地层单位具有跨代性。根据大地构造演化特征和新发表的同位素年龄数据,将各大地构造单元划分为10个构造演化阶段,各阶段均形成了优势大地构造相和相应的矿产资源。在一定的大地构造演化阶段、一定的大地构造相分布一定的矿产或矿床组合,不同大地构造单元各个构造阶段的相系清晰反映了矿床的空间分布规律。根据矿床形成的地质构造环境、成矿作用等特征,将河南省众多矿床厘定出27个矿床成矿系列。文章基于大地构造演化进行矿床成矿系列的划分是一种新的探索。Tectonic units in Henan Province are composed of North China Block, Qinling Orogenic Belt and Yangtze Block. There is a consensus on the tectonic unit division of the North China Block in pre-middle Jurassic in Henan Province. However, the debate on the division of tectonic units of Qinling Orogenic Belt has never stopped because of the cross-generation nature of rock-stratigraphic unit. In this paper, according to the characteristics of tectonic evolution and newly published isotope age data, the authors divided tectonic evolution into 10 stages with different dominant tectonic facies and mineral resources. The spatial distribution of ore deposits is clearly reflected by the mineral or mineral deposit association which formed in a certain geotectonic evolution stage and geotectonic facies and tectonic facies series developed in each tectonic stage in different tectonic units. According to the geological tectonic environment of ore deposits and mineralization characteristics, 27 metallogenic series of mineral deposits were set up in Henan Province. The division of metallogenic series of ore deposits based on geotectonic evolution in this paper is a new kind of exploration.
