| Characteristics and Dynamic Analysis of Inter-Crystal Brine Movement in the Lop Nur Salt Lake |
| Based on general movement regularity of underground water, this paper describes in detail physical characteristics of brine aquifers and dynamic properties of brine movement as well as their variation in Luobei depression lying in the northeast of Lop Nur, Xinjiang. With such means as 14C-dating, I 131 technique and chemical tracing technique, the authors studied the rate of circulation, the flowing direction, the vadose velocity and the actual flowing velocity of inter-crystal brine in Luobei playa, thus revealing the chronic flowing and exchange state of the inter-crystal brine. In addition, it is shown that various factors such as neotectonic activity, paleoclimate change, hydrostatic pressure of strata, oilfield water and precipitated water have exerted controlling influence on the movement of inter-crystal brine. Finally, a model of inter-crystal brine is suggested. |
