| 中文摘要: |
| 母山含矿斑岩体内及附近发育NNE向、老EW向、新EW向构造及属于局部构造的NNW向构造和弧形构造。其中,NNE向构造为成矿构造.随着时间演进,成矿构造应力场活动强度逐渐减弱,频率逐渐增强。并且,主应力轴σ1的产状也随时间由向SE陡倾变为水平,最后倾向NW。在成矿构造活动强度较大时,控制了与成矿有关的岩体侵入;在成矿构造活动频率较大时,控制了热液活动及有关的成矿作用。 |
| 英文摘要: |
| Structure trending in NNE direction,old structure in EW direction,new structure in EW as well as local NNW trending structure and arc structure occur in and near Mushan porphyry body.The NNE structure is the ore-host structure.With the temporal evolution the activity strength of its structural stress field gets weaker and weaker but the activity frequency stronger and stronger.At the same time,the dip direction of the principal stress axis changes from SE to horizontal and finally NW.The strong activity strength controls the intrusion of rock bodies related the mineralization and the high activity frequency controls the hydrothermal mineralization. |
