Lithium and boron are widely used, and our country import ore perennially. Recently, a special world class lithium and boron deposit was found in Serbia Jadar basin. Like Rio Tinto, Pan Global Resources and Ultra Lithium, Chinese geological prospecting institute will doing exploration work in it, so it's necessary to report the geological characteristics of the deposit. The ore minerals is unique in the world, which contains both lithium and boron, called jadarte ［LiNaSiB3O7(HO)］. It contains B2O3 47.2% and Li2O7.3%, weight 2.46g/cm3. According to the data, The wall rock is Miocene lacustrine sedimentary rock. Lithium and boron are most likely the volcanic origin, showing as that jadarite zone appears near the tuff horizon. The characteristics of ore body is that the resistivity is less than 4.4 Ωom and the gravity negative anomaly, generally less than -15 mGal. Infrastructures are sufficient; Mine method is well mining; Ore beneficiation is convenient and raw materials are available, so lithium and boron can be produced in short period.
