| Salt Lake is a lake formed under specific natural geographical and geological environment,strong solar radiation,windy drier climatic conditions of evaporation play development to the final product,which is characterized by solid-liquid coexistence,brine penetration current unified geological body.Salt Lake vast reservoir of mineral salts,more categories,has a long history of mining.Salt Lake contains large amounts of rock salt,Glauber's salt,gypsum,potassium,magnesium,boron and other mineral salts.In addition,the occurrence of lithium,bromine,rubidium,strontium and other scarce resources available for exploitation in the Salt Lake.Salt Lake is a treasure trove of mineral resources in China,as one of the world's largest dry salt lake,Luobupo salt lake,brine bears rich in potassium,sodium,magnesium,calcium sulfate material resources associated with lithium,bromine,strontium,boron and other rare elements.According to its own characteristics of Luobupo salt lake,Luobupo salt lake playa remote sensing maps,reference to past research in Luobupo salt lake,the regional comprehensive analysis of the Luobupo salt lake salt lake brine geochemistry,which reveals the Luobupo salt lake brine water chemical characteristics,summarize material characteristics and the distribution of resources and the content of rare elements.In order to understand the distribution of the elements characteristic of the Luobupo salt lake brine,the Loubei area of Luobupo salt lake surface was collected brine samples 46 plane features of analysis of ionic concentration;drilling LDK-01(700m)deep one,by top-down pointssegment to take samples 52,analysis of the Salt Lake Brine ion the longitudinal distribution characteristics.The results showed:(1)The analysis shows that the impact of the strong evaporation,Luobei area concave surface area of salinity maximum 389.25g/L,the average 330.47g/L,respectively.The Law North brine salinity was high in the middle and low on both sides of the oval scatter,slightly lower than the south and north.Law North concave to the east(northeast-southwest planing surface)high salinity are greater than 338.20g/L.(2)The Luobei hollow surface area constant element of the content in a higher level,major cations in the brine for K +,Na +,Ca2+,Sr2+,B3+,anion mainly as Cl-,SO42-,HCO3-,Br-,I-.Including K+,Na+,Li+,CL-,SO42-,B3+ distribution and content was positively correlated with the degree of mineralization,Ca2+,Sr2+ distribution and content was negatively correlated with salinity.HCO3-,Li+,Br-,I-,Mg2+ the distribution and the relationship between content and salinity is not obvious.(3)Through the analysis of 52 samples of the LDK-01 wells,vertical,brine salinity overall distribution slight downward trend,peak about 130m salinity 366.91 g/1.300m after the overall law of a downward trend,there are some fluctuations but relatively stable,the highest value of 321.26g/1,the lowest point between 470?500m,is 266.93g/1,average for 305.50g/liter.The deep brine salinity is relatively uniform and stable,only 470 to 500m at lower.(4)In terms of vertical brine salinity overall distribution of a slight downward trend.And in vertical aspect,the content of each chemical component in the brine changes with depth variation of performance for the three forms:? liter decrease with depth,such as magnesium ion,sulfate ion,sodium ion,etc.;? increased with depth,such as calcium ions,chloride ions,heavy bicarbonate ions;? obvious changes with increasing depth,such as strontium ion,lithium ion,a bromine ion and the like.?,(2)elements of content strongly influenced by evaporation,the first ?class elements content is influenced by supply sources. |
