本文首先研究了一中酸性杂岩体在不同的构造环境中,在不同力学性质结构面中的侵位特征,进而,侧重分析了处在不同力学性质结构面中的同一岩浆岩石在结构、构造、矿物组成、岩石化学成分及矿物稳定性等方面的变异特征。在考虑差应力作用之外探讨了这种构造岩浆岩相的力学原因,即是由于构造应力所产生的附加静水压叠加在这一深度上的静水压(围压)上,使得不同力学性质结构面中产生不同的局部总静水压而造成的。
In this paper, we first investigate the emplacement characteristics of an intermediate acidic complex in different structural environments with different mechanical properties. Then, we emphatically analyze the characteristics of the emplacement of the same magmatic rocks in structural planes with different mechanical properties, , Mineral composition, petrochemical composition and mineral stability and other aspects of the variation characteristics. In addition to considering the effect of differential stress, the mechanical reason for the structural magmatic facies is discussed. The additional hydrostatic pressure due to tectonic stress is superimposed on the hydrostatic pressure at this depth (confining pressure), so that different mechanics The nature of the structure of the surface to produce a different partial total hydrostatic pressure caused.
