摘要
热液矿床的矿体主要受断裂空间的控制．这些破裂空间的产生直接受控于构造应力偏张量的作用．应力偏张量为零的深度是构造动力驱动矿液运移的极限深度．应力偏张量等于岩石极限强度的叠加部位是矿化的极限深度．
ydrothermel ores are controlled mainly by fracture,while fracturing is controlled directly by deviatoric tensor of tectonic sterss.The depth where the deviatoric tensor is zero is the maximun depth of migration of ore fluid driven by tectonic stress.The depth where the deviatoric tensor is equal to ultimate strength of rock is the maximum depth of mineralization.
