Several conclusions are drawn from the study. The ore deposit mainly occurs in the lower Cambrian Shuigoukou Formation, which is situated at the limbs of Qingshixia-Yujiatai overturned multiple syncline. The ore-hosted rocks are silicalite and mudstone. The content of SiO2 is high in the rocks of V ore deposit. Silicalites are mainly aphanitic quartz and chalcedony and the barite is sedimentogenic. The correlation between V and Cr, U, Ba is good. The rare earth element distribution patterns show Ce-negative or positive anomaly, obviously Eu positive anomaly and the right dip graphics.

研究结果表明，该区钒矿主要产出于青石峡－余家台倒转复式向斜两翼下寒武统水沟口组下岩段硅质岩夹泥岩的泥岩中，矿体产状与地层产状基本一致；钒矿床中所有岩石都含有较高的SiO2，硅质岩以隐晶质石英和玉髓为主，有沉积成因重晶石；V与Cr、U、Ba相关性好；稀土元素球粒陨石标准化模式具有或正或负的Ce异常和明显的Eu正异常、向右倾的图形。

According to petrographic facies test, gravel sample mainly consists of quartz, albite, dolomite, and minor biotite; and sand sample is mainly made up of quartz and albite. As an important ASR active mineral, chalcedonite exists in fractures of dolomite and in matrix of cherty limestone. In rapid mortar bar test, expansion of sand, small gravel and middle gravel at 14 day are less than 0.1%, but keep increasing in long term.

岩相法检测显示卵石样品主要由石英、钠长石及白云石和少量云母类矿物组成，砂样品主要由石英、钠长石等矿物组成，重要的碱活性物质玉髓主要出现在白云岩裂隙和硅质灰岩的基质中；&砂浆棒快速法&检测结果显示砂、小石、中石样品14天的膨胀率均不超过0.1％，为非碱－硅酸反应活性骨料，但卵石样品仍具有一定的碱活性，且后期膨胀率一直持续增长。
