| 摘 要： | 陕北奥陶纪盐盆地是我国目前发现最大的海相成盐盆地之一,笔者重点对该盆地最新完钻的5口钻井(米探一井、绥一井、佳一井、子洲一井、吴堡一井)原状岩芯的马五-6亚段进行系统野外编录及采样。并对其进行了沉积学、矿物学和地球化学的综合研究,结果表明,马五-6亚段成盐卤水演化已达钾石盐沉积阶段,尤其是东南部的绥一井岩芯的矿物学和地球化学特征显示其含钾显示较好,预示着陕北奥陶纪盐盆地具有成钾远景。

| Abstract: | The Ordovician Northern Shaanxi Basin is one of the largest marine salt-forming basins found in China up to now.The authors conducted systematic field documentation of the original-state cores recovered from five wells(Mitan No.1,Sui No.1,Jia No.1,Zizhou No.1 and Wubao No.1)completed recently in the sixth submember of the fifth member of the Majiagou Formation in the basin and performed integrated sedimentological,mineralogical and geochemical studies.The results indicate that the evolution of the salt-form... |
