摘　　要：　南召-方城成矿带位于华北板块与北秦岭造山带接合部位。从控矿地质条件、矿床(点)空间分布特征、成矿物质来源及矿床成因等方面,总结出"一体两带"的三维成矿模式,即燕山期花岗(斑)岩体("一体")控制矿床的分布,岩体两侧的两条韧性剪切带则同时具有控岩控矿的特点。NanzhaoFangcheng mineralization belt lies at the junction of North China plate and North Qinling orogenic belt. According to the geologically orecontroling conditions. Spatial distribution of ore deposits (occurrences), ore material source and genesis of the ore deposits the oreforming model of 'one bodytwo zones' is put forth, ie Yanshanian granite bodies that control ore deposit distribution, two duclile shear zones on the either sides of the granite body that control distribution of the bodies and ore occurrences.
