| 摘 要： | 分形不仅能揭示地质现象的复杂程度，且在某种程度上反映了地质过程的成因本质。上杭－尤溪地区的分形研究表明：①侵入岩的分形值普遍较小，火山岩的分形值普遍较大；②火山岩的分形值与应力成正相关，而侵入岩则相反；③分形值受区内大型的政和－大埔断裂、上杭－云霄断裂、永安－晋江断裂控制；④火山岩的分形值接近于临界值时对成矿有利。

| Abstract: | Fractal can to some extent reveal complicated characteristics and reflect genetic essence.Fractal characteristics of magmatic rocks in Shanghang-Youxi reveal the following phenomena:(1) fractals of extrusive rocks are larger than fractals of intrusive rocks;(2)fractals of extrusive rocks are in positive relationship with paleostress. Fractals of intrusive rocks are in negative relationship with paleostress;(3)fractals are controlled by crustal or mantle faults such as Zhenghe-Dapu fault,Shanghang-Yunxiao fault and Yongan-Jinjiang fault;(4)volcanic fractals approaching critical values are advantageous to metallogeny. |
