The Study Of Sedimentary Characteristics And Nitrogen Source Of Nitrate Deposit In TKW, Lop Nur, Xinjiang

The TKW is a part of the Lop Nur playas in the north-east comer of Lop Nur.There is little study on TKW nitrate deposit since being found by, author systemly study its geology and geochemistry characteristics in this text.Through the particle analysis, author identified the sediment style of TKW. After contrast in diffirent area, Rebacked the paleotectonics environment since Quaternary in TKW. And author also had a good description to it's chemic characteristics,mineral characteristics, sedimentary characteristics.Anthor translated one piece of 1∶20000 geological map of TKW. Identified the deposit style according to the other specialists's description of nitrate deposit. Also named a few little basions in TKW.And, author had done much X-ray energy chemical anylesis etc. identified most mineral of this region, found the geochemstry rhythm of K,Na,Ca,Mg,Cl,Br,I,NO₃, etc.It often has diffrent views about the resource of nitrogen. After phothchemical reuctions experiment in different temperatures found that the influnce of temperature to the relation is obvious in higher and lower temperature.Finally, the author discussed the new method in forcasting the nitrate deposit on the basis of experiment of photo chemical reactions.
