Salt lake carbonate resources: The trona ore of salt are mainly distributed in the Inner Mongolian salt lake area, with a total reserves of trona and soda of thousands of tons (NaHCO3+Na2CO3), and the Qagan Nur lake is one of the biggest trona ore; the hydromagnesite are mainly distributed in Tibet salt lake area, and the Bankog lake has a large deposit scale.
Salt lake Sulfate resources: the mirabilite resources of salt are distributed in the Inner Mongolian, Xingjiang, Qinghai and Tibet salt lake area. Some smaller scale of mirabilite resources are widely distributed in the Inner Mongolia and Xingjiang salt lake area, and the East Dabancheng salt lake and East Qijiaojing salt pond are known to have large mirabilite deposits. The mirabilite resources in Qinghai salt lake area are very rich, observes the Hans lattu ore deposit scale to be biggest, the personal status is best, the mining condition is superior; Tibet salt lake area's modern salt lake mirabilite deposition grows, the ore deposit scale is common above hundred million tons, like Baingoin is wrong, Guo Jialin is wrong, the Iraqi cloth tea card, grips salt lakes and so on warehouse tea card. The celestine resources only distribute in the Qinghai salt lake area Qaidan Basin mid-west, famous has the gale mountain, the apex mountain ore deposit. In the sulfate salt lake the gypsum deposition growth is widespread, but has not constituted the large-scale ore deposit. The astrakhanite distributes in the Shanxi Yuncheng salt lake and middle Qaidan Basin some salt lakes, the sulfuric acid sylvite deposition only discovers in Zarb Ye Lake of Tibet and big Lakes Beach region of Qinghai.

Salt lake chloride resources: The halite resources are very widespread in Chinese salt lake, and the most well known ones include Jartai, Salt Lake yabrai in Inner Mongolian, Baytik salt pond in Xinjiang, chaka, keke and Cha Er Han salt lake in Qinghai, markov, Zarb Ye Chaka salt lake in Tibet. And salt lake chloride resources in Qinghai salt lake area are most abundant.

Salt lake borate resources: The salt lake borate resources mainly distributed in Qinghai and Tibet salt lake areas, especially in the North Tibet lake area. The Qinghai borate resources mainly distribute in Dachaidan and Xiao Chaldan Salt Lake, pinnoite and ulexite being the main ore type; in modern salt lake of Tibet, the borate deposition is mainly distributed in Bangonghu, Chiao Tung zone and many salt lakes nearby the North Tibet road like Baingoin, Guogaringcuo and in Neiercuo, Zacangchaka salt lakes etc. In addition there are also massive borate deposition hosted in Ka-erh Kunsa, Cha-rakka and Zhabuyechaka Salt Lake in Ngari area.

Salt lake bittern resources: The salt lake bittern resources are distributed in Xinjiang, Inner Mongolia, Qinghai and Tibet salt lake areas. Xinjiang, Inner Mongolian, Tibet salt lake areas distribute mostly the sulfate, chloride and carbonate of sodium. There are abundant chloride-type brine resources but no carbonate-type brine in Qinghai salt lake areas, with the potassium chloride resources reserves accounting for above 70% of soluble salt resources reserves. Like the Tibet salt lake area, the sulfate, chloride and borate of sodium, potassium, magnesium and lithium are the main salt resources in Qinghai salt lake area.
