下伏基岩 meaning in English
subterrane
underlying bedrock
Examples
- The results demonstrate that the pingba red residua is a typical in situ chemical weathering crust , and the material sources of the profile are derived from underlying triassic dolomites , the chemical weathering of dolomite can be divided into two stages : " leaching - accumulating trend " and weathering trend " , the stable teconic and whole weathering of dolomite should be the main reason for the development of thick and consecutive red weathering crust overlying dolomite rock in central guizhou
结果显示该剖面是下伏基岩白云岩风化成土并累积的结果，无其他外来物源，是原位风化壳；成土过程具有两阶段模式特征，即白云石、方解石的溶蚀酸不溶物累积和酸不溶物进一步风化两个阶段；长时期的构造稳定和白云岩整体溶蚀作用是黔中地区白云岩风化壳土层厚度大、分布连续的主要制约因素。 - The unconformability between the loess landform of shaanbei loess plateau and its bedrock shape was pointed out first after the full demonstration . the top of loess formation of the south part in shaanbei is flat which likes " platform " , the shape of the bedrock is rolling that likes ridge , and the bedrock bended to fold . the top of loess formation of the mid - part in shaanbei is rolling , but the shape of the bedrock below begins to get flat , the top of loess formation of the north part in shaanbei , loess mao district , is much more rolling among them , however , its shape of the bedrock below is the flattest relatively likes the platform shape of loess formation in south
具体地讲，陕北高原南部的洛） 11黄土源，黄上层顶部相对平坦，地貌类型以黄土源为主格调，而其下伏基岩地层诏皱相对发育，古地势起伏相对较大：陕北高原中部的延安一安塞黄土梁状（为主）丘陵沟壑区，黄土层顶部起伏相对增大，地貌类型以黄土梁为主格调，而其下伏基岩地层槽皱程度趋弱，地层较平缓，古地势起伏相对降低；陕北高原北部的绥德一子洲黄土赤状（为主）丘陵沟壑区，黄土层顶部起伏度相对最大，地貌类型以黄上赤为主格调，而其下伏基底地层以平缓为特征，古地势起伏强度亦相对较低。
