新疆乌勇布拉克盐湖的形成及硝酸钾矿床特征

详细论述乌勇布拉克盐湖的沉积的全过程,并将其划分成3个阶段,每阶段沉积物都有自己的特点,但总体趋势是由机械沉积过渡到化学沉积,通过蒸发试验和“干盐湖”理论进一步确定钾硝石矿产牛在当代干盐湖向沙下湖转化阶段．乌勇布拉克盐湖固相、液相KNO3矿体特征具有代表性,对其他盐湖钾盐找矿有指导意义．

FORMATION OF WUYONGBULAKE SALT LAKE IN XINJIANG AND CHARACTERISTICS OF POTASSIUM NITRATE DEPOSIT HUANG TIEDONG

The largest potassium nitrate deposit in China is found in Wuyongbulake Salt Lake in Xinjiang. Potassium-rich source, continued dry weather and good converging water conditions contribute to the formation of the deposit. The sedimentation process of Wuyongbulake Salt Lake is described in detail. The process is divided into three stages, with each stage having uniquie sedimentological features,.At the same time there is a general transition from mechanical sedimentation to chemical sedimentation. Evaporation experiments and the "Dry Salt Lake" theory, show that potassium saltpeter is formed while the dry salt lake is being buried under sand (lake under sand). The characteristics of solid and liquid potassium nitrate deposits have representative features that can be used as guides in searching for new potassium nitrate deposits in nearby areas.
