- The DTA curve of the fine clay fraction exhibits a major exotherm near 340℃. 这种细粒土级分的DTA曲线接近340℃处有一个很大的放热峰。
- Clay fraction is dominated by illite and kaolinite with small proportions of smectite, chlorite and vermiculite. 粘粒组成主要为伊利石和高岭石,也有少量蒙皂石、绿泥石和蛭石。
- It is believed that, whether fine magnetite being bacterial or detrital, its enrichment in the clay fraction is a common feature. 无论细晶粒磁铁矿的成因如何,其在粘土中富集是普遍现象。
- The application of pig manure resulted in the increase of the enrichment coefficients of SOC and TN in coarse sand, while the decrease in clay fraction, especially in coarse clay. 粗砂粒中有机碳、总氮的富集系数升高,黏粒(尤其是细黏粒)中富集系数降低;
- K-rich illite. Mg-, Ca-, Na-, Zn-rich smectite, Mn- and Fe-rich chlorite produce a clear coupling relationship between clay minerals and chemical compositions of clay fraction. 富K的伊利石,富Mg、Ca、Na、Zn的蒙皂石,以及富Mn、Fe的绿泥石等使得粘土矿物与粘土级组分的化学元素之间的耦合关系十分明显;
- Also,X-ray diffraction studies indicate that the hematite contents in fine-earth fraction and clay fraction rise with increase in soil-forming age and that magnetite descends while maghemite ascends in content. X-射线衍射结果表明土壤细土和黏粒中赤铁矿含量与风化成土时间呈正比增加。 同时,土壤有磁铁矿含量减少、磁赤铁矿增加的趋势。
- At present, there is seldom construction application of the stabilized earth road subbase using low liquid limit silt soil or sandy silt soil with few fine clay fractions. 粘粒含量很少的低液限粉土或含砂低液限粉土做稳定土路面底基层,目前施工实践较少。
