| 摘 要： | 云南兰坪—思茅盆地和楚雄盆地都是含盐盆地,沉积了广泛的古近纪古新统含盐地层。通过对所采样品的地化指标及前人研究成果的分析,认为兰坪—思茅盆地内古新统含盐系成盐阶段的卤水浓缩度呈由北向南逐渐升高的趋势,其总体浓缩阶段高于楚雄盆地,成盐成钾条件优于后者。前者的物质来源可能以古海水为主,后者则显示其成盐环境可能为内陆湖盆。

| Abstract: | Yunnan Lanping-Simao basin and Chuxiong basin are both important basins containing extensive salt deposit of Paleocene.Based on the geochemistry characteristics analysis of the samples which we obtained and previous research,the results show that the trend of the degree of brine concentration in Paleocene of Lanping-Simao basin was gradually increased from north to south.The overall degree of brine concentration in Lanping-Simao basin is higher than Chuxiong basin,and the salt or potash ore forming environm... |
