摘要
热液矿床成矿深度受成矿期构造空间的控制,构造空间为古构造应力场所致。构造应力场中偏应力张量为零的深度是构造变形的极限部位,岩石的强度极限与偏应力张量达到零值的叠加部位是成矿的极限深度。
The ore-forming depth of the hydrothcrmal deposit is controlled by the structure space which was caused by palcotcctonic stress field during the mineralization. The depth where the dcviatoric-strcss tensor in the structure stress field is zero is the limit depth of structure deformation . The depth where the ultimate tensile strength of the rock coincides with zero value of the dcviatoric-stress tensor is the limit ore-forming depth.
