ABSTRACT Rock is a kind of natural complicated damage materials. The extraordinary characteristic of rock medium is the irregularity of meso-strueture and the indefinity of mechanical behaviours.

岩石是复杂的天然损伤材料，其突出特点表现为结构的不规则性和力学行为的不确定性。

Optimalerror estimates in L2-norm and H1-norm are obtained.Model:The mathematical model for two phase incompressible flow innaturally fractured reserviors is[34]:Supposeis a bounded domain with smoothy boundary,the rock ispresented byΩi,the volume of the fissures is small,Ωm=Ω.In the fissures Ω:s(x,0)=s0,x∈Ωin the rock Ωi:where J=0,T.

模型：裂缝孔隙介质中油水两相不可压缩驱动问题的数学模型为[34]：设〓为具有光滑边界的有界凸域，其中多孔岩块以Ωi表示，Ωm＝∑Ωi，因裂缝体积很小，可以认为Ωm＝Ω。x在裂缝系统Ω上：〓s(x，0)＝s0，x∈Ω在任一岩块Ωi上：〓其中J＝0，T。

Increase of that clast of sedimentary rock, high-grade metamorphic rock and unstable heavy minerals shows tectonically active setting and obvious uplift of Bogda Mountain during the Late Jur.

新疆博格达地区中—新生界碎屑成分自中侏罗世的中晚期开始发生了巨大变化，主要表现在：自中侏罗世晚期开始，沉积重矿物组合及相对含量发生较大变化，不稳定重矿物、较高级别变质岩岩屑明显增多，显示此时发生的物源属性变化及构造活动的存在；自侏罗系西山窑组沉积晚期开始，砂岩碎屑成分中的沉积岩碎屑明显增加，显示盆缘沉积岩物源的隆升和剥蚀作用。

We think main metamorphic rock types of this area include mited granite ,mixed metamorphic rock,leptite,etc.

认为变质岩中混合花岗岩、混合岩化变质岩、变粒岩、浅粒岩、黑云斜长片麻岩等为本区的主要变质岩类型；沉积岩以云岩、硅质岩和石英砂岩为主；火成岩脉主要为辉绿岩、煌斑岩和闪长玢岩。

The hydraulic properties of rock masses are likely to be highly heterogeneous even within a single lithological unit if the rock is fractured.

由于岩体中通常包含有大量的各种尺度的裂隙，因此其力学和水力学性质即使是在单一岩性岩层中也是高度非均质的。

The contact - metasomatic iron deposit, which emerges between intermediate - acid magmatic rock and carbonate rock, is controlled by geologic structure.

产于中酸性岩浆岩与碳酸盐岩接触带的接触交代型铁矿，受地质构造条件的控制，在安林地区形成了两条成矿带，包含8个矿田。

In addition, our works also indicate that MC-ICPMS technique shows a good potential on Re-Os isotopic measurement. 2. A new method for the determination of low Re-Os abundances and ~(187)Os/~(188)Os in a natural rock sample by MC-ICP-MS has been established in our laboratory. Rock samples were digested in inverse aqua regia in sealed Carius tube for 24 hours at 230°C, then Os was separated from the matrix by CCl_4 solvent extraction, and further purification by microdistillation.
