| 摘 要： | 南极洲万达盐湖为饱和方解石湖水。计算出的方解石饱和指数随水深增加而变化。在Ca~(2+)及HCO_3~-活度值均一的上部氧化环境湖水中,pH及溶解氧(DO)是控制该变化的主要因素,在下部还原环境湖水中,Ca~(2+)及HCO_3~-的活度对方解石的饱和指数SI的变化起主要作用。这充分揭示了湖底部近代沉积物中分布较多方解石矿物的原因。

| Abstract: | Vanda Salt Lake in Antarctica is saturated for calcite, and calculated saturation indices for calcite vary with an increase of water depth, pH and dissolved O_2 are major factors to control this variation in upper oxidation lake water with roughly homogeneous system of Ca~(2+) and HCO_3~- activity values calcium and bicarbonate activities are major factors to control while this variation in the lower reduction brine. These reveal the mechanism of calcite mineral formation in the recent sediments of the lake bottom. |
