| 摘 要： | 绝大多数的金矿化作用都是在非平衡的开放体系中完成的,再加上硫化物在结晶过程中生长速度过快,因此难免产生一些异常特征:晶格金在硫化物中大量出现、含金硫化物单晶中主元素含量变化很大以及主族元素Si加入硫化物晶格等。这些异常特征在皖南东至金矿化区得到了良好的体现,其成因是不能用经典的平衡态热力学和晶体化学理论来解释的。

| Abstract: | An overwhelming proportion of gold mineralizations occurs in disequilibrium open systems. Meanwhile it is resulted in a lot of abnormal phenomena which can not reasonably be explained by classic thermodynamics and crystallochmistry. The Dongzhi gold field is represented by such disequilibrium phenomena as: abundance in lattice gold, varied range of end-element contents in gold-bearing arsenopyrite and Si contamination in pyrites rich in lattice gold. |

| Keywords: | disequilibrium open system lattice gold gold metallogenic field |
