研究侵入岩体(它们的结晶作用、围岩改造、温度场的分布以及构造不均匀性的发育)的形成动力学有两个主要困难。其一,所获得的地质和地球化学资料都带有统计性质,而且是基于对成矿作用最终产物所作的分析。根据侵入体内部构造、接触变质相、岩体内部及周围分布的金属和非金属的矿物组合等的制图所查明的动力学要素,不能了解例如作用在空间和时间上发展的全貌。其二,要对侵入体及其周围岩石进行总体观察,这甚至对于那些揭露得最深、研究得最透的对象来说都是不可能的。
There are two major difficulties in studying the formation kinetics of intruded rocks (their crystallization, wall-rock modification, distribution of temperature fields, and development of structural heterogeneities). First, the geologic and geochemical data obtained are statistical in nature and are based on an analysis of the final product of the mineralization. According to the dynamical elements identified by the mapping of intrusions’ internal structure, contact metamorphic facies, metallic and nonmetallic mineral assemblages distributed inside and around the rock mass, it is not possible to understand the overall picture that develops, for example, in space and time. Second, an overall observation of the invaders and the rocks surrounding them is impossible even for those who are most exposed and thoroughly researched.
