摘　　要：关中盆地属于新生代断陷盆地,其新近系灞河组—蓝田组沉积相类型以及环境演化对于地下水分布规律具有控制作用。本文通过野外地质剖面的观察,沉积岩轻、重矿物组分、沉积结构构造、砂/地比值、古生物特征、物源方向等分析以及编制盆地内主要单井相图以及层组的沉积相平面图,认为主要发育有冲积扇相、扇三角洲相、河流相及湖泊相。文中探讨了各主要沉积相带的展布规律及其对地下水分布规律的控制作用,为地下水资源的开发奠定了基础。Guanzhong basin belongs to the fault basin of Neogene,the stratum of Neogene include Bahe -Lantian formation,it is therefore important to make types of sedimentary facies and the evolvement of the sedimentary environment research in order to analyse the law of the distribution of underground water. Based on observation of the geologie section,analyzing the variation of light/heavy mineral components of sedimentary rocks,the sedimentary structures and textures,the ratios of sandstone to formation of sedi- me...
