第四章盐湖成因大多数盐湖的形成过程反映了其周围的地质、地球化学和自然地理特征。气候的长期干旱或半干旱,地貌成闭塞或半闭塞的盆地、洼地、泻湖,对盐湖的生成和发展有决定性作用。此外,由于工农业生产活动,某些地方还可能在很短历史内形成盐湖,如苏联的腊斯瓦尔盐湖就是挖掘亚粘土盖层和岩盐后在人工盆地形成的;中亚细亚草原沙漠的农业灌溉促进了河谷阶地和河流的干涸三角州上形成盐湖;美国内布拉斯加的桑德山含钾碱湖则是因印第安人多年烧毁松杉林等,经水淋漓其灰烬形成的。
Chapter 4 Salt Lake Formation The formation process of most salt lakes reflects the geological, geochemical and geophysical characteristics of the surrounding area. Long-term arid or semi-arid climate, blocked or semi-occluded basins, depressions and lagoons play a decisive role in the formation and development of salt lakes. In addition, because of the industrial and agricultural production activities, salt lakes may also be formed in some places in a short history. For example, the Salt Lake Salt Lake in the Soviet Union was formed in man-made basins after excavation of sub-clay caprock and rock salt. Agricultural irrigation in the Central Asia Prairie Desert The salt lake was formed on the dry delta of the river valley terrace and river. In the United States, the mountainous lake of Thunder Mountain, Nebraska, was formed by the Indians’ burning of cedar forests for many years.
