According to petrologic analysis of 18 samples of altered rock, phlogopite rock , with regard to its B 2O 3 content, it is generally restricted to the outside of the ore bed, having certain ties with the boron minerlization while no ties are found in altered rock of the same type associated with veins of diorite porphyrite.

其中金云母岩多分布在含矿层外带，通过对 1 8件金云母岩样品中B2 O3含量分析，表明正常蚀变岩中的金云母岩与硼矿有一定的关系，而由闪长玢岩脉体侵入影响下形成的金云母岩则与矿化无关。

Static rock mechanics is important in rock burst researches, but it can not explain the whole mechanism of rock burst.

The strength of rock material has the characteristics of random distribution. Combined with Mohr′s criteria, theory result is acquired to analyse the variation in strength of rock material by use of damage mechanics. By comparing this theory result with a group of experiment data on Carrara marble, it is shown that the damage mechanics model is suitable for describing the constitute property of rock material.

首先论述岩石材料强度的概率统计特性，结合经典的莫尔准则，利用损伤力学理论分析了岩石强度随围压的变化，给出了三轴应力状态下的岩石本构关系的表达式，并与Carrara大理岩在各种围压下的应力-应变曲线进行对比。

Because whole rock samples always contain some retrograde minerals,the tie line of garnet + whole-rock in Sm-Nd isochron diagram or the tie line of phengite + whole- rock in Rb-Sr isochron diagram can give a geologically meaningless age.

由于全岩样品总是含有数量不等的退变质矿物，因此石榴石+全岩 Sm-Nd 法或多硅白云母+全岩 Rh-Sr 法将有可能给出无地质意义的年龄。
