| 摘 要： | 鄂尔多斯盆地黄土区土壤可以划分为碎屑、粘土、杂基与次生碳酸盐矿物（胶结物）三大类。次生碳酸盐胶结作用形成许多微集合体，改变了土壤粒度的固有特性；粒度分布可划分为特征不同的三个区间。粘土矿物决定土壤酸解烃的区域背景，碳酸盐矿物是形成酸解烃异常值的决定因素。不同温度处理可以使酸解烃显著性明显增强。

| Abstract: | The soil in the losses covered area in Ordos basin consists three types ofminerals,i.e. debris,clays(matrix)and secondary carbonate minerals(cement).The cementation by secondary carbonate minerals forms a great number of micro aggregates,whichresults in great change about the characteristics of grain size distribution of the soil.The grainsize distribution may be devided into three intervals,Clay minerals in the soil control theback- ground of soil- acid hydrolysis hydrocarbon.Secondary carbonate minerals form the mostimportant cause for the abnormal value of soil-acid hydrolysis hydrocarbon. And.heatingtreatment at different temperature can be very helpful for outstanding the result of thismethod. |
