摘　　要：大汶口盆地岩盐矿均为第四系所覆盖,钻孔揭露,除第四系外,主要为古近系官庄群大汶口组。大汶口盆地主要是由南留断裂所控制。岩盐矿是大汶口盆地盐类矿床的主体,矿层多而集中,厚度大而变化小,品位高而稳定。矿层延展面积约45km2,其平面形态为一个椭圆形,在空间上整个含盐段似一个向北缓倾的大透镜体。矿石自然类型有3种,即块状岩盐(灰白盐)、含杂质岩盐(杂色盐)和脉状岩盐,其中以块状岩盐为主,含杂质岩盐次之,脉状岩盐不具有工业意义。该矿床地质条件好、埋藏深度适宜,外部建设条件好,该矿床具备大规模开发的条件,矿业开发可促进当地的经济发展。当地政府有关部门已在着手工作,推动该岩盐矿规模开发进程。It prospects at third grade. 21 phosphorite fields have been put forward for the further work. Covered by the Quaternary System ,and controlled by Nanliu fracture, the Dawenkou basin composed of Da Wenkou formation of Guanzhuang Group ,paleogene System. Halilith in Dawenkou basin spreading 45km2 , take the shape of ellipse and looklike a big lens leaning northward. There are three types of ore types, which are mainly massive halilith, less halo-sylvite and veinlet halilith has no industrial significince .Investigation shows its conditions of large scale development for the better geological setting and suitable imbedding depth and fight surrounding construction conditions. Developping work is getting down by the department concerned of local government.
