摘要
Abstract
Makgadikgadi salt lake area is a modern dry salt lake, which is dominated by lacustrine detrital sediment. There is high mineralized pore brine occurrenced in Suagan salt lake on the east side of Makgadikgadi. Through the sampling, analysis and comprehensive study of brine of salt lake, it is found that there is high mineralized pore brine in Sua Pan salt lake on the east side of the lake. The main chemical components of brine are Na+ and Cl-, followed by CO2-3,HCO- 3,SO2-4, K+, the average salinity is 257.96g/L, and the chemical type of brine is carbonate type. There is a significant positive correlation between brine composition and salinity, indicating that the brine has not reached the saturation stage, and the rich area of brine is located in the northwest of the study area, which is also the area with the highest salinity due to the influence of the lake region structure and the source of replenishment. The content of KCl is between 0.39% and 0.999%, with an average of 0.65%, which has exceeded the lowest industrial grade of liquid potash ore, and the distribution area is about 690km2. It has a certain prospect for prospecting.关键词
