A STUDY OF INTRUSIVE CONTACT STRUCTURES
-
摘要: 本文介绍了作者运用地质力学方法、原理并借鉴国际研究动态,涉足侵入接触构造研究获取的部分成果。基本要点包括:(1)侵入接触构造自成系统;(2)可分3种基本型式;(3)是岩体侵位动力和区域构造应力双重作用的结果;(4)控矿构造的多期活动与水压破裂相关;(5)一般所谓外接触带构造,实质为热动力变质构造.Abstract: This paper gives the major conclusions of intrusive contact structures achieved by authors by applying the theory and methods of geomechanics:(1) the intrusive contact structures themselves form a system which,falling into three basic types,results from the combined action of the emplacement of intrusives and regional tectonic stress;(2) multi-phase activity of ore-controlling structures is related to hydrofracturing;(3) the outer contact structures generally are referred to essentially as thermodynamic metamorphic origin.
