| 摘 要： | 勐野井钾盐矿床的成因,众说纷纭.笔者将此矿床和兰坪思茅坳陷沉积盆地的演化与板块构造活动相结合,提出侏罗纪古钾盐矿经再溶蚀、再沉积、再改造的成因假说.认为今后在兰坪思茅坳陷探盐找钾的新方向是深埋在地下的中侏罗统和平乡组及下侏罗统,有可能在此层位找到大型或超大型的海相固体古钾盐矿床.

| Abstract: | There are many opinions of the genesis of Mengyejing K salt deposit. We put forward the genesis hypothesis of resolution, re-sedimentation, re-reformation of Jurassic palaeo-k salt deposit, in combination of this ore deposit with the evolution of Simao depression sedimentation basin and plate tectonism. We think that the new direction of the future K and salt prospecting in Lanping-Simao depression is the deeply buried Middle Jurassic Hepingxiang Formation and Lower Jurassic, maybe the large or super-large scale marine solid palaeo-k salt deposit will be discovered in these horizons. |
