各种岩石(岩层)或流体,在构造动力作用下,原先均匀分布的各种物质顺应构造应力场的要求,在不同部位或相对富集,或相对贫化,称为动力分异。这里讨论了五种类型动力分异,即:断裂带的动力分异,改造型旋卷构造动力分异,建造型旋卷构造动力分异,层控矿床改造动力分异以及与混合岩、花岗岩化有关的动力分异。文中论述了它们各自的分异特征,分析了分异的动力学原因,应用动力分异观点探讨了区域成岩成矿作用,并对找矿工作提出了一些设想。
Under the action of tectonic forces, all kinds of rocks (rocks) or fluids that are originally uniformly distributed conform to the requirements of the tectonic stress field and are enriched or relatively depleted at different sites and are called dynamic differentiation. There are five types of dynamic differentiation discussed here, namely, dynamic differentiation of the fault zone, dynamic differentiation of the revolving spiral structure, dynamic differentiation of the constructional spiral coil structure, dynamic differentiation of the stratabound mineralization transformation and integration with the mixed rock and granite The power of differentiation. In this paper, their respective differentiation characteristics are discussed. The reasons for the dynamics of differentiation are analyzed. The regional diagenetic mineralization is discussed with the view of dynamic divergence. Some assumptions are made for the prospecting work.
