摘　　要：对最新编制的桐柏山—大别山地区区域重力、航磁、化探等资料做了阴影、纹理分析等图像处理 ,获得了不少新信息。这些信息在区域构造的分区、断裂带的厘定、隐伏地质体的确定、找矿预测等方面 ,特别对提出印支—燕山期陆陆碰撞缝合带、南北大别块体及木兰山块体 ,做出了重要的贡献 ,取得了满意的效果。Image processing techniques such as shadow and lamination analysis were developed for the newest compiled regional gravity,aeromagnetic and geochemical data of Tongbaishan Dabieshan area.As a result,plenty of information has been obtained.The information contributes greatly to the division of tectonics,the determination of faulted belts and concealed geological bodies,the ore prospecting prognosis and,especially,the suggested Mulanshan block related to the expansion of northern and southern Dabieshan blocks along the suture zone caused by Indosinian Yanshanian continent continent collision.The achievements are satisfactory.
