But the geological and geochemical analyses showed that there existed a set of high quality marine source rock in the platform slope facies of Middle Ordovician Pingliang Formation. The oil and gas generated from the source rock of Pingliang Formation was accumulated firstly in the central Palaeo-uplift and its surrounding regions. The thermogenic asphalt in palaeo-uplift carbonate reservoir indicated that oil accumulation completed transition from oil to gas in the Lower Crataceous. Along with the palaeo-uplift axis convection and the formation of westward monocline in the Late Crataceous, gas from the palaeo-reservoir was finally accumulated in the weathering crust of Majiagou carbonate reservoir.

地质和地球化学分析证实，盆地西、南缘台缘深水斜坡相的中奥陶统平凉组存在优质海相烃源岩，其形成的油气最早富集在中央古隆起及其周围；伴随着中央古隆起带轴部的向东迁移和早白垩世末盆地西倾大单斜的定型，平凉组烃源岩在早白垩世生烃高峰期生成的天然气和早期古油藏裂解气，由中央古隆起带向北东方向发生二次运聚，最终在盆地中部奥陶系马家沟组风化壳中聚集成藏，即形成靖边大气田。

The NITROGEN CYCLE. Some of these cycles are regulated mainly by weathering.

这些循环中的一些是由物理因子调控的，例如磷循环的主要限制因素是通过岩石的侵蚀作用缓慢释放的磷酸盐。

So rational using soil opsonin such as weathering coal furfural residue in calcareous soil, can improve the phosphorus validity and the utilization ratio in soil.

因此，在石灰性土壤中合理地施用风化煤、糠醛渣等土壤调理剂，可以增加土壤中的磷的有效性和提高磷肥的利用率。

Yanshan movement and the Himalayan orogeny, but also after years of weathering erosion, while the sculpture into the current look.

燕山运动和喜马拉雅造山运动，又经多年风化剥蚀，而雕塑成现在的面貌。

The results showed that the heavy metals in various mediums were mainly Cu and Ni, and those concentrations were, in the descending order, in ditch, tailings, slagheap and cultivated soil. In the tailings and the sludge of the ditch, the concentrations of Ni were obviously higher than those of Cu. Whereas, in the soil and the weathering and atmospheric deposition of the waste slagheap surface, the concentrations of Cu were higher than those of Ni. This means that in the first two mediums, Cu and Ni mainly originated from the tailings, while in the latter two mediums, Cu and Ni mainly came from the atmospheric deposition of airborne particles of the smelting. Cr and Zn were mainly in residual fraction, Cu was mainly in oxidizable and residual fraction.

结果表明：不同区域环境中重金属呈现不同程度累积，其中以Cu、Ni最为显著，含量由高到低依次为尾矿坝排污沟＞尾矿坝＞废渣堆＞农田土壤；尾矿砂和沉积物中重金属分布以Ni含量显著高于Cu含量为特征；而农田土壤和风化物及降尘中重金属分布以Cu含量高于Ni含量为特征，前者Cu、Ni主要来源于尾矿，后者与冶炼烟尘排放有很大关系；样品中除Cr、Zn以残渣态为主外，Cu、Ni、Pb化学形态分布有较大差异，Cu以可氧化态和残渣态为主，Ni以可还原态为主，其次为弱酸提取态，Pb以可还原态为主，其次为残渣态。

A historical region of southwest France between the Pyrenees and the Garonne River. The duchy of Aquitaine was joined with France after the marriage of Eleanor of Aquitaine to King Louis VII in1137, but its possession was disputed after her subsequent marriage to Henry II of England.
