北淮阳构造带为一条沿大别造山带北麓展布的狭长构造带，是华北板块与扬子板块碰撞造山的产物，其物源组成、构造属性等研究内容是揭示南北板块在中国东部的大地构造单元格局以及时空演化的关键信息。结合构造变形、岩石学、岩石地球化学、锆石U Pb年代学等方法对北淮阳前中生代岩石地层单元苏家河群/卢镇关群和信阳群/佛子岭群进行对比分析，就其构造属性形成这样的基本认识：北淮阳构造带是杨子板块向华北板块俯冲-碰撞的结合带，其物质组成具有双源性-主体部分来源于杨子板块，由代表了杨子板块北缘基底的晚元古代苏家河群（784±19Ma）/卢镇关群(756±12Ma)和杨子板块被动陆缘复理石沉积建造-中泥盆世至晚泥盆世早期的信阳群南湾组组成，后者相当于商丹缝合带以南的刘岭群；信阳群龟山组亲缘于华北板块并构成华北板块南缘的弧前楔形沉积体，是沿商丹缝合带分布的桃花铺弧前楔形沉积体的东延。佛子岭群总体可与信阳群相连，全岩成分显示，佛子岭群沉积构造环境既有活动大陆边缘，又有被动大陆边缘。由于中生代以来多期构造变形叠加（至少三期），佛子岭群岩石地层单元的叠置关系被改造或重置，使其缺少“构造解体”的证据，而无法在构造单元上细分。对于两大板块之间的缝合带位置，笔者认为：商丹缝合带进入北淮阳构造带后，应沿着北淮阳的北界，与龟山-梅山-六安-磨墩水库一线延伸的断裂带相连。
The Beihuaiyang tectonic zone is a narrow NWW—SEE trending tectonic belt located on the northern foot of the Dabie Mountains, the product of amalgamation between North China block and Yangtze block. Study of the sedimentary provenance and tectonic property reveals key information about the tectonic framework in this region and the dynamic evolution of Qinling—Dabie orogen. Based on comprehensive analysis of pre Mesozoic lithostratigraphical units in Beihuaiyang using structural geology, petrology, geochemistry and isotopic chronology, the following understanding has been acquired. The Beihuaiyang tectonic belt is a compound tectonic belt resulting from subduction and collision between Yangtze block and North China block. Its provenance derived from double source regions Yangtze block and North China block. The late Proterozoic lithostratigraphical units— Sujiahe Group（784±19Ma） and Luzhenguan Group(756±12Ma) represent the basement of the northern margin of Yangtze block, while flysch sequence and the middle to late Devonian Nanwan Formation represents the passive continent margin of Yangtze block. The latter is equivalent to the Liuling Group in south of the Shangdan suture zone. The Guishan Formation of the Xinyang Group is linked compositionally with the North China block. It serves as the fore arc wedge sedimentary bodies that distributes along the southern margin of North China block and is the eastward extending of Taohuapu fore arc wedge sedimentary bodies. The Foziling Group connects westward with the Xinyang Group. Whole rock analysis shows that sedimentary settings of the Foziling Group include both active continent margin and passive continent margin. Because of the superimposition of multiple structural activities (at least three times) since the Mesozoic, the lithogoical and stratigraphic unit of the Foziling Group has been reformed and thus tectonic unit can not be classified in detail. For the suture zone between two plates, authors propose that the Shangdan suture zone, after extending the Beihuaiyang tectonic zone, connects with the faulting zone of Guishan Meishan Lu’an Modun reservoir along the northern boundary of the Beihuaiyang.
