中文摘要	通过对比新疆巴里坤地区基岩、湖积物和土壤中相关化学成分发现,研究区基岩相对陆壳贫Mg,Ca,Fe,Al等主要成分和Cr,V,P,Zn等微量元素;湖积物则出现了Ca,Mg,(Fe)相对基岩的富集,Al,Cr,Ba,V的进一步贫化;在较干旱环境下形成的土壤基本保持了基岩的P,K含量特征,表明该地松散沉积物既有对基岩化学成分的继承,又有在此基础上的地球化学分异.
英文摘要	The intermontane basins in the northern piedmont and northern slope of the Tianshan Mountains are the important zones of industrial and agricultural development and urban construction in Xinjiang. The chemical compositions of the loose sediments in these regions not only affect the local ecological nvironment, but also are related to the distribution of the agricultural and animal husbandry economy and the structure of planting. In this paper, the chemical compositions of the bedrocks, sediments and soils in the Barkol region, Xinjiang, are analyzed. The results show that the bedrocks here are poor in the main elements, such as Mg, Ca, Fe and Al, and in some trace element, such as Cr, V, P and Zn; the lacustrine sediment is rich in Ca, Mg and Fe but poor in Al, Cr, Ba and V; the characteristics of P and K contents of the bedrocks are remained in the soils formed under the arid environment, which reveals that the chemical compositions of the bedrocks are remained in the loose sediments, and on which there are also some geochemical variations in the loose sediments after suffering from the climatic fluctuation, complicated weathering, transport and sediment processes over 10 000 years. Thecharacteristics of chemical compositions of the bedrocks and sediments mentioned above can provide the reference for improving the soils and environment in future.
