| 摘 要： | 本文从成矿构造应力场入手,研究了成矿构造应力场控矿的应变能原理及矿液运移原理,认为主应力和（σ１＋σ２）与主应力差（σ１－σ２）决定了应变能的大小和矿液运移势的高低,它们都体现。在此基础上对矿床中经常出现的４种典型构造在不同边界条件下进行了佤息光弹模拟实验,发现应变能的分布、成矿流体的运动和集中与构造应力场密切相关,应变能的高梯度区和矿流体运移的低值区是成矿的有利构造部位,文中还介绍了一些控矿实例

| Abstract: | In this peper, the authors discuss the ore-bound principle of strain energy and ore solution migration under a specific tectonic stress field that prevaiced during mi neralization. It is thought that strain energy and migration potential are controlled by the sum and difference of the principal stresses (σ1+σ2), (σ1-σ2).Photoelastic experiments of four typical structures under different boundary conditions indicate that the movement and concentration of ore-forming fluid is closely related to the tectonic stress field:the ore deposits are most likely to form where the strain energy gradient is steep or the fluid migration potential is low.Some examples of the typical structures are given. |
