By study hongyan deposit on minerogenetic and geological background , mineral constituent , rock alteration , rare - earth element , isotope and typomorphic feature of sulpurization mineral , we made a conclusion that the feature of haongyan is deposition - rebuilding desposit 通过对红岩矿床的成矿地质背景、矿物成分、围岩蚀变、稀土元素组成、同位素以及硫化物的标型特征进行研究，确定了红岩矿床的成因为沉积?改造型矿床。
Abstract : the resource characteristics such as the composition , texture , structure and the prospects of industrial utilizations included white carbon black , alc13 , 4a zeolite , al - si alloy and rubber filler of coal - series kaolinite in huainan and huaibei mining area were introduced 文摘:在分析了两淮煤系高岭岩矿石的结构和构造、矿物成分、化学成分、热变性等性质的基础上，探讨了两淮煤系高岭岩资源在白炭黑、氯化铝、 4a沸石、铝硅系列合金、功能性填料等工业应用前景。
When dim pile is applied in work of a freeway project , it is conducted as a study issue , because both the theory about it is not very clear now and also the quality control is hard to demonstrate , in addition , there is a big difference among soft soils in different areas on the distribution , the ingredient of minerals and the physical and mechanical properties 由于这一方法的理论还太完善，施工质量控质也有一定难度，加上不同地区软土的土层分布，软土的矿物成分、物理力学性质等差异性极大，所以每项高速公路工程在采用粉喷桩处理软基时，都将其列为一项研究课题。
And it should be ascribed to silt according to the view of its mineral composition , particles distribution , physical and mechanical indices . not only is the content of cla > relatively high , but also the exchange capacity of ion , chiefly high - electronvalent calcareous ion , is great . due to aggregations filled with pore among inter - particles , the soil has the engineering properties of silty clay 从其矿物成分、颗分试验及物理力学指标来看，它应归属于粉土，但由于土中的粘粒含量较高，且粒间充填集聚体，土的离子交换容量较大，交换阳离子以高价钙离子为主，故其仍表现出粉质粘土的工程特性。
Diagenesis not only can change mineral composition , fabric component , and texture , etc . , but more important it can change the reservoir capability greatly , that is , it can build up , or reduce , or enlarge original pores , and even form a series of diagenetic crack . those secondary pores and cracks are important to improve reservoir capability , especially for carbonate 成岩作用不仅使岩石或沉积物的矿物成分结构组分构造等发生程度不同的变化，更重要的是使原岩的储集性能发生很大的变化，即对原生孔隙或堵塞或残留或扩大，而且还可产生一系列的成岩孔缝次生孔缝，这些次生孔缝对岩石储集性的良化，尤其是对碳酸盐岩是至关重要的。
The basic physical and mechanical properties , mineral composition , micro structures , swelling potential , consolidated drained triaxial shear strength , parameters of constitutive model and residual strength of the soft clayey rocks were tested in laboratory with a large number of natural samples . the changing trend of the strength about these rocks is obtained by modeling the condition of softening due to immersion . from the principles of modern soil mechanics , the structural and swelling characteristics of soft clayey rocks were analyzed systematically 本文通过现场调查，查明风化泥质软岩的宏观结构特征，利用现代试验测试手段，取原状土系统进行特殊土室内土工试验，测定土的基本物理力学特性、矿物成分及微观结构、膨胀性、三轴排水剪强度及本构模型参数、软化残余强度，并模拟土体在长期浸水软化后的强度变化趋势，测试该类土的浸水软化残余强度。
The dispersibility as well as seepage distortion and salt transference under long - term seepage condition of soil samples obtained from the clay core wall in xijiao and sanping reservoirs were studied by physical and chemical properties of soil and composition of clay mineral and the tests for identification of dispersive clay soils which included double - hydrometer test , pinhole test , crumb test , tests to defermine salt content of pore water and percentage of exchangeable sodium 摘要应用碎块、针孔、双比重计、孔隙水可溶盐和交换性钠百分比等五种试验方法，结合物理化学性质和矿物成分分析，对西郊、三坪两水库大坝心墙土样进行了多种方案的分散性试验及长期渗流条件下的渗透变形试验和盐分运移试验。
Taking it for example that zhujiabaobao section of panzhihua vanadic titano - magnetite deposit , the paper detailedly analysed its change regularity in ore texture and structure , mineral composition and content , ore chemical composition , mineral chemical composition , rare element " s change feature of rock and ore , exploding temperature of mineral inclusion . on the basis of above , the feature of rhythmic texture of ore body in panzhihua vanadic titano - magnetite deposit was researched 本文以攀枝花钒钛磁铁矿朱家包包矿段为例，详细分析了该矿段中矿石组构、矿物成分及含量、矿石化学成分、矿物化学成分、岩石及矿石稀土元素变化特征、矿物包裹体爆裂温度等的变化规律，进而研究了攀枝花钒钛磁铁矿矿体中的韵律结构特征。
