摘　　要：有限单元法是实现构造应力场从定性描述到定量、半定量计算的有效手段。在研究区域控矿构造特征的基础上，建立了研究区地质体的离散化模型，确定了边界条件和本构关系，模拟出内蒙古腮忽洞地区热液金矿床（含金石英脉型和蚀变岩型）成矿构造应力场和能量场，从而为该区金矿综合找矿预测提供了一种新方法。Finite element is an efficient method to realize stress field from qualitative discription to quantitative and semi-quantitative calculation.On the basis of regional orecontroling structure study a dispersedmodel for geological body has been built up,boundary conditions and constitutive relations have been established and the stress field and energy field during mineralization period have been imitated,thus a new method for the regional gold mineral deposits prognosis has been provided.
