中文摘要	选取新疆塔里木盆地及准噶尔盆地的2个典型终端干盐湖罗布泊和玛纳斯盐湖,对其成钾条件和模式进行对比分析,分别从盆地地理纬度,构造位置,盆地规模,所处气候带以及区域水文化学特征,盐类矿物组合特征,钾盐富集特征和品位等多个方面进行了研究.罗布泊地区气候干燥指数>150,补给河流的rho(K)10~2/rho(Cl)比值为3.29:1~5.08:1,晶间卤水的rho(K)10~2/rho(Cl)比值为3.71:1~6.66:1,卤水氯化钾品位1.4%,资源量达3.2亿吨.而玛纳斯湖干燥指数为8.63,补给水源的rho(K)10~2/rho(Cl)为1.5:1~12:1,晶间卤水rho(K)10~2/rho(Cl)为0.1:1~1.6:1,卤水氯化钾品位0.33%,资源量为37.23万吨.研究结果表明,罗布泊在气候和物源补给上都比玛纳斯湖具有明显优势,有利于形成大型钾盐矿.2个干旱区典型盆地可观察实验的成钾指标对比分析,对于建立蒸发岩盆地成钾指标模型具有重要的参考意义
英文摘要	This paper provides a comparative analysis of the indicators of potash deposition in the aspects of geographical latitude, tectonic location, basin size, climate zones, hydrochemical characteristics, mineral assemblages, potash enrichment features and brine grades between the Lop Nur, the terminal lake of the Tarim Basin, and the Manas Salt Lake in the Junggar Basin of Xinjiang. The results show that the Lop Nur basin is superior to the Manasi Salt Lake in climate background and potassium supply and is thus favorable for the development of large-size potash deposits. In the Lop Nur basin, the aridity index is higher than 150 and the main inflow water has the rho(K)10~2/rho(Cl) ratio from 3.29:1 to 5.08:1; in addition, the intercrystalline brine has the rho(K)10~2/rho(Cl) ratio of 3.71:1 to 6.66:1, the KCl content of 1.4% and potash resource quantity (KCl) of 3.210~8 t. By contrast, the Manas Salt Lake has an aridity index of 8.63 and the rho(K)10~2/rho(Cl) ratio of main inflow water from 1.5:1 to 12:1; besides, the intercrystalline brine has the rho(K)10~2/rho(Cl) ratio of 0.1:1 to 1.6:1, the KCl content of 0.33% and potash resource quantity (KCl) of 37.2310~4 t. This quantitative analysis of the potash deposit indicators for these two typical basins will promote a better understanding and development of the potash indicator pattern in the arid evaporative basins of western China
