| 中文摘要: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。 |

| DISCUSSION ON VARIATION OF MAGMATITE FROM STRUCTURAL PLANES OF DIFFERENT MECHANIC PROPERTIES IN SHICAO MINING AREA |
|
|
| Abstract:This paper discusses first the characteristics of emplacement of a complex of neutral acid magmatic rocks in the different tectonic environments and in the structural planes of different mechanic properties, and places emphasis on the research of the variational characteristics of texture, structure, mineral constitution, chemical composition and stability of crystallized minerals of the same magmatic rock situated in the structural planes of different mechanic properties. Without deviatoric stress being taken into account the mechanic genesis the magmatic structural facies is explained to be caused by different local total hydrostatic pressure head in the structural planes of dif- ferent mechanic properties produced by the combination of hydrostatic pressure head (confining pressure) at a depth with the additional pressure head by the structural stress in the structural planes. |
