| 摘 要： | 通过区域构造、古气候、成盐物源聚集及保存条件的分析表明,地处陕北的鄂尔多斯台蚴具备有利的成盐环境,且已在部分地段见钾盐矿物及薄层钾盐。这使之成为目前中国找钾最有希望的地区。其中,镇川堡-米脂-绥德一带的中奥陶统马家沟组五段中部(O_2m~(5-6))应成为今后找钾工作的重点。

POTASH-HUNTING PROSPECTS OF THE ORDOVICIAN SEQUENCES IN NORTH SHAANXI WITH REFERENCE TO THEIR GEOLOGICAL CONDITIONS |
| |
| Abstract: | The Eerduosi syneclise in North Shaanxi has been proven as qualified for favourable salt-genetic condition though investigations into its tectonic characters, palaeoclimatie fluctuation and capability to trap and preserve salts.In fact,potash minerals or thin beds has been discovered at the eastern part of the syneclise which is thus regarded as the most promising region of the country for searching for potash resources.Meanwhile,the central level of the No.5 member of the Middle Ordovician Majiagou group should be given preference in the coming potash prospection. |
